Abstract:

Ozone is one of the most powerful oxidizing equipment, so it is effectively used to kill bacteria, viruses, and fungi. Many industrial processes use ozone because ozone can run without forming a by-product in water. Nevertheless, the utilization of ozone in Indonesia has not been applied maximally, due to the large cost of commercial ozonator equipment and operational life that is relatively short. In addition, many still do not comprehensively comprehend the ozonation process that is relatively very fast in the presence of ozone conditions that can only last a few minutes before parsing back into oxygen. In this study, the DBD (Dielectric Barrier Discharge) plasma reactor model with parallel plates for ozone generation at room temperature was developed. Furthermore, this study is more focused on conducting performance tests and optimizing ozone productivity in parallel spacer corona discharge chambers. This designated ozonator was treated as a plasma reactor to perform various tests with varying feed flow rates, input voltages, and gas feeds (compressed air and medical oxygen). After the productivity of the ozonators were tested with iodometric titration method, the ozonator’s productivity in generating ozone and its optimum operating condition were obtained. It can produce up to 0.82 g ozone/h with compressed air feed and 6.45 g ozone/h with medical oxygen feed.

The main object of the research is the efficiency of real-time ozonator control based on sensor networks. The study addressed the issue of low efficiency in ozonator control systems and the lack of reliability and speed in real-time data transmission. The research revealed that changes in pressure and temperature have a direct impact on ozone concentration. This finding made it possible to increase the ozonator's productivity by 15 %, reduce energy consumption by 10 %, and improve system reliability by 20 %. The key features of the results include the ability to monitor ozone levels in real-time, maintaining the stability of the ozonator, and optimizing its performance. Additionally, sensor networks ensured fast and accurate data delivery, enhancing the energy efficiency and reliability of the system. These results were explained based on experimental data that demonstrated how changes in pressure and temperature affect ozone concentration. The use of sensor networks contributed to increased system stability, reduced energy consumption, and improved control accuracy. The obtained results can be applied to ozonator systems and other fields requiring real-time environmental monitoring and control.

Abstract:

Abstract This article presents an installation for producing ozone. Ozonators have found widespread use in agricultural production. The most efficient means of ozone production today are ozonators using electric discharge. They are simple in design and have high ozone yield in comparison with other methods. The ozonator is designed with the use of discrete elements, CMOS logic elements of medium integration, and operational amplifiers of medium accuracy. The design elements have galvanic connection to the 220/380 V network. The device consists of the following main functional elements: a master oscillator, a signal conditioning device, a display device, an amplifier, a high-voltage output stage and power supplies. This ozonator is intended for use in agricultural production, in particular for the treatment of crops. Experimental trials of the laboratory ozonator were carried out concerning treatment of winter wheat seeds with ozone to improve their sowing qualities. Particularly, winter wheat seeds were subjected to ozone treatment with ozone concentrations of 2.5, 35.0 and 55.0 mg/m3. At these concentrations, the dependence of germination energy of winter wheat seeds on the exposure and settling time from the moment of treatment to seed germination was determined. As a result of research, energy of germination increased by 17.0 % in comparison with the control, germinating capacity in the best variant changed from 77.0 % to 95.0 %.

Abstract:

In research work the problem of studying the process of ozone control with the help of electronic sensors is considered. In research work, special sensors were used, which are formed around coronary electrodes in the ozonator and to monitor the concentration of ozone in the room. This is because ozone is known to adversely affect human health if its maximum permissible air concentration exceeds 0.16 mg/m3. A small system of ozonators was developed in a special laboratory, theoretical and experimental tests were carried out. In practice, the obtained data and the electric diagram of the ozonator (on the ARDUINO platform) were collected. "Prana Air" sensors and current sensors were used to accurately determine the ozone (O3) concentration around the ozone nozzle to measure the current at the electrodes.

Abstract:

The greatest danger from the point of view of infection of farm animals is the air inside the production premises. One of the ways to improve performance and improve the air environment is ozonation. The article proposes the design of an autonomous module of an electric ozonator operating on the basis of a corona discharge, designed to improve the air environment and prevent the spread of contagious animal diseases. A distinctive novelty of the proposed design is the emitter module, made in the form of two ceramic bases with tungsten electrodes fixed on them, on one base in the form of a grid having a honeycomb cell shape, on the other in the form of a needle. Structurally, the emitter provides for adjusting the distance of the discharge gap between the electrodes of the emitter, which ensures the adjustment of ozone performance and increases the reliability of the ozonator as a whole. The results of experimental studies on the ozonation of the volume of the room using an autonomous module of the electric ozonizer operating on the principle of a corona discharge are presented. It has been established that the concentration of the ozone-air mixture increases with an increase in the operating voltage at the emitter electrodes and a decrease in the distance between them. The maximum performance indicators of the installation for ozone (10 mg/m3) were obtained at an operating voltage of 30 kV at the emitter and a discharge gap of 25 mm. An experiment on the effect of ozone concentration in the air on pathogenic microflora showed the effectiveness of the application to reduce pathogenic microflora in the air.

Abstract:

The article discusses ways to increase the efficiency of ozone production in a coaxial chamber using a pulsed corona discharge. The effect of the discharge gap and the diameter of the potential electrode on the energy efficiency of ozone production using a pulsed corona discharge of negative polarity with duration of 40 ns and voltage of about 100 kV was investigated. It is shown that with an increase in the discharge gap, the productivity of the installation decreases, and the energy efficiency increases. The optimal diameter of the potential electrode has a value of about 0.64 mm. This information will be useful in the development of highly efficient ozonators and in optimizing the parameters of plasma-chemical reactors for air purification by electro-discharge methods.

Abstract:

Technological schemes of processing textile materials with special chemicals are considered. A method of reducing the concentration of heavy metal ions in waste water of textile manufacturing enterprises based on the combination of effluents from different technological lines is proposed. To reduce the degree of oxidation of chromium (Cr6+ to Cr3+), as well as to transfer salts of copper, cobalt, nickel and other metals from a liquid to a solid state, it is recommended to mix such wastewater with effluents containing sodium or potassium sulfide. The method can be used at enterprises of the chemical, printing, and paint industries. To reduce the content of sulfides of various metals in wastewater and obtain colloidal sulfur, a method of oxidation of such salts by ozonation using a special ozonator is proposed. Ozonation also makes it possible to reduce the content of organic substances in the total volume of effluents to standardized indicators.

Abstract:

This research is aimed at improving the ability of oily wastewater biodegradation through the ozonation method, where ozone will oxidize organic compounds in the oily wastewater that are diffi cult to be degraded by bacteria so that the structure becomes simpler. The ozonation process is done by using a corona-discharge ozonator and semi-batch reactor, and the process is varied by ozone dose and pH value. The ozonation process is then followed by a biodegradation process, where the bacteria that is used is Pseudomonas sp. This study also observed the effect of surfactants in supporting the biodegradation processes. An indicator of research success is the increase in the biodegradation percentage of the sample, followed by an increase in the value of the constant rate of bacterial growth. The research results shows that the ozonation method and the use of surfactant can support the oily wastewater biodegradation process. This is shown by the value of the biodegradation percentage and the constant rate of bacterial growth results, in which respective values are able to reach 86,787% and 0,339 at the optimal operating conditions (ozone dose of 0.53 g/h; pH 7; Bios-H surfactant concentration 500 ppm).

Abstract:

Ozone enters into chemical reaction with many organic compounds. Ozone is a very strong oxidant. It oxidizes most of the elements to higher oxides. In the oxidation reaction by ozone activity second only to ﬂuorine, its oxide and free radicals. It is formed from oxygen by absorbing heat in this case, and, conversely, when the expansion goes into oxygen, giving oﬀ heat. The main method of obtaining ozone for practical purposes is electrosynthesis. In industrial conditions for using ozone and corona discharge barrier. Ozonizers corona discharge can signiﬁcantly increase the eﬃciency of ozone by reducing capital and operating costs for the process equipment and ozonation. Research shows that ozone air ozonator pulsed mode increases the resistance of animals to the action of microorganisms factor. In animals and poultry in industrial production often develop diseases caused by pathogens factor. These diseases mainly occurring symptom of lesions of the respiratory and digestive systems. In many countries today conducted research using ozone, and the results of these studies are published in the course of scientiﬁc-metric database. For normal growing animals, especially young animals, premises should be thoroughly disinfected. Disinfection is required for all technological facilities as livestock and poultry. Experimentally found that ozone has a bactericidal eﬀect (for example, test cultures E. coli) on diﬀerent surfaces (wood, Petri dish) considering its concentration and exposure. The results of inﬂuence of diﬀerent concentrations of ozone in ozonair mixture is fed into the container of the Petri dish, and time impact on survival of microorganisms provides a fairly accurate prediction of the results of impact parameters ozonation.

Abstract:

The research on phenolic compound degradation using chemical oxidation methods in a plasma reactor was performed with an Ozone-Plasma Hybrid Reactor (RHOP). This device operates by combining ozonation reactions in the liquid plasma within the reaction room. Furthermore, Ozone gas as a reagent is produced by the standard ozonator type Resun RSO-9805 made in Hong Kong and fed into this device, where the liquid phase is mixed within the injector. This way, the two-phase mixture reacts more intensively in RHOP. Also, this combination is designed to intensify hydroxyl radicals while the liquid phase is in an alkaline condition constantly exposed to plasma. The results demonstrated a continuous circulation for 2 hours at the initial concentration of 50 ppm for p-chlorophenol with a volume of 2 liters. This further obtained an 83.98% removal rate and 42.19% COD value decrease.

Abstract:

This article highlights the significance of developing a digital control model for the electric drive of the ETRO-03 ozonator, aiming to improve the stability of ozone production, boost system performance, and lower energy consumption through advanced control techniques. The electric drive, being crucial for ozone generation, plays a key role in determining the ozonator’s efficiency. To accomplish these objectives, mathematical models were created and simulated in Python to represent the system's dynamics. The study analyzed essential parameters of the electric drive, such as current, angular velocity, inductance, and resistance. Initial fluctuations in current and angular velocity were quickly stabilized, with the system’s inertial effects examined. The current peaked at 20 A before stabilizing at 18 A, while angular velocity reached 150 rad/s, later stabilizing at 145 rad/s. The system achieved stable operation within 10 milliseconds. The inductance (0.05 H) and resistance (2 ohms) were identified as critical in stabilizing current and angular velocity. Friction torque played a significant role during the initial phase but had minimal impact during steady-state operation. Overall, the research confirmed that integrating digital control systems can enhance the ETRO-03 ozonator’s performance.

Abstract The peculiarities of the formation of the mineral composition of mine waters are considered. The main processes for cleaning mine water and the factors that influence the choice of cleaning methods and schemes are listed. This article provides a mathematical evaluation of the efficiency of ozonator control via a sensor network during the process of underground water purification in mines over a 10-minute period. The aim of the study is to monitor the ozone concentration precisely, enhance water purification efficiency, and conserve energy. The ozone concentration decreased from 1 to 0.2 within the first 5 minutes, while the purification quality reached 0.8 during this time. Energy efficiency increased to 0.35 within the first 2 minutes, but gradually decreased, reaching approximately 0.2 by the 10th minute. Throughout the study, real-time monitoring of the ozone levels via the sensor network allowed for process optimization. The results demonstrated the effectiveness of sensor-based control in preventing excessive ozone consumption and improving water quality. In conclusion, ozonator control through a sensor network was proven to be an environmentally friendly and energy-efficient method.

Abstract:

One of the most important tasks of animal husbandry is establishing and maintaining normalized microclimate parameters in closed livestock keeping houses: temperature, humidity, speed of air fl ows, illumination, gas composition of air, and suspended dust particles. Failure to comply with established zootechnical and veterinary-sanitary standards in a closed room, (other things being equal) can lead to a decrease in productivity, increased feed consumption per unit of production, the rapid development of pathogenic microbes, and the spread of infections. The design of an electric air ozonizer based on a corona discharge and an air ozonization system is proposed to ensure high-quality air disinfection in livestock keeping houses in accordance with sanitary standards. A distinctive novelty of the proposed design is the emitter module, made as a ceramic base, on which tungsten electrodes are fi xed in the form of a grid with a honeycomb cell. The advantages of the proposed design of an electric air ozonizer include the reliability of operation due to shutdown in case of an emergency, protection against overheating and critical concentration of ozone inside the room in one place due to a weather vane, ozone and temperature sensors, and a central control unit. The proposed design of the electric ozonation system will increase the effi ciency of disinfection and disinsection of air in industrial livestock buildings, and will also ensure a more uniform concentration of ozone throughout the room volume due to the location of ozonizers and their improved operation of the emitter in terms of performance and uniformity. Preliminary evaluative experimental studies to test the performance of the proposed electric air ozonator in a livestock keeping house with an area of 1600 m2 have shown that its design reduces the amount of microfl ora in the air from 27520 to 240 colonies/m3, while increasing ozone concentration to 0.035 mg/m3, as well as reduces the content of harmful gas impurities of hydrogen sulfi de from 0.16 to 0.0003 mg/l; ammonia – from 0.13 to 0.05 mg / l; carbon dioxide – from 10 to 0.2 mg/l.

Abstract:

Objective. To assess the effectiveness of the low-dose air ozonation for disinfection of the air in the working room. Materials and methods. We investigated 90 air samples (3 samples were taken weekly before and after the production meeting using the automatic sampling device of biological aerosols of air PU-1B). The total bacterial contamination, the content of staphylococci and mold spores were determined. Ozonation of the room (83.3 m3) was carried out for 20 minutes by means of domestic ozonator. The accumulated dose of ozone was 133.3 mg (1.6 mg/m3). Statistical data processing was carried out using the MedStat licensed program. The median, median error (Me me), left and right 95 % confidence intervals (95 % CI) were calculated. Paired comparisons were made using Wilcoxon's T-test. Results. After the meeting, the total bacterial contamination of the air was 56.0 9.3 (47.078.0) CFU. The content of staphylococci and mold spores in the air was 85.5 12.5 (76.0100.0) and 44.5 6.5 (32.054.0) CFU, respectively. After ozonation, the total bacterial contamination of the air was 14.5 3.6 (10.021.0) CFU. The content of staphylococci and mold spores in the air after ozonation was 35.5 6.7 (25.052.0) and 26.0 5.0 (18.032.0) CFU, respectively. Ozonation of the room provided a significant decrease (p 0.001) in all three of the above indicators. The room ozonation carried out promoted a reliable decrease (p 0.001) in all the above mentioned parameters. Conclusions. The above data and analysis of the literature show the possibility of using low doses of ozone for the prevention of bacterial, fungal and viral infections including SARS-CoV-2. Further study and development of reasonable modes of ozone disinfection, including low doses of ozone, is needed, as well as determination of the efficiency degree of air disinfection with non-toxic gas concentrations.

The article discusses the features of the use of activated oxidation technologies in ship stations for the preparation of drinking water. The processes of disinfection of drinking water using cavitation, UV-radiation, ozonation are considered. It is shown that the use of the listed highly efficient processes can significantly reduce the need for reagents, improve the weight and size indicators, and the energy consumption of ship drinking water preparation stations. The use of a unit for complex disinfection by ozonation and UV-radiation, which combines the functions of an ozonator and a UV-disinfection device, is proposed. The use of this device can increase reliability, maintainability, reduce weight, dimensions, and electricity consumption by the drinking water preparation station as a whole. The advantages and disadvantages of these methods of disinfection of drinking water are indicated. A functional diagram of drinking water preparation stations using the synergistic effect of activated oxidation technologies is substantiated. Keywords: drinking water disinfection, cavitation, UV-radiation, ozonation, ship water supply, activated oxidation technologies, drinking water preparation station, drinking water preparation technology.

Abstract:

The clinical efficacy of rehabilitation treatment under the impact of ozone therapy has been studied in patients with ischemic heart disease. 155 patients with exertional angina of I and II functional classes were examined in a health resort. Of them, 105 patients underwent ozone therapy on the ozonator made by firm «Medozone» (Moscow) with ozone concentration 2,5-3 mg/l. The results of the research testify to the high clinical efficacy of the method at the expense of the activation of oxygen supply mechanism and rising of the functional reserves of cardiovascular system. The method of parenteral introduction of ozone oxygen mixture extends opportunities of the management of stenocardia patients with high risk for complication development and availability of concomitant diseases.

Abstract:

Relevance A promising direction for the development of domestic and foreign eIn the modern world, more and more attention is paid to environmental issues. One of the effective ways to solve environmental problems is the use of ozone - an allotropic modification of oxygen, which has high oxidizing abilities and can be used to purify and sterilize water, air and exhaust gases. However, the spread of technologies related to the use of ozone is hampered by their energy intensity. In this regard, an urgent task is to optimize the design of ozonizers and its power supply mode to reduce the specific energy consumption for ozone production. The main aim The aim of this article is to study the dependence of the efficiency of ozone formation on the frequency of the supply voltage and to determine the optimal frequency at which this efficiency would reach its maximum value. Research objects Ozonizer. Research methods Mathematical modeling of physical processes. Results An expression is obtained to determine the distribution of the electric field strength in the discharge gap. An iterative algorithm has been developed, as a result of which graphs of the dependence of the critical frequency value on the amplitude of the supply voltage, as well as on the temperature and pressure of the gas passing through the discharge gap, are obtaine

Abstract:

In order to save the cost of expensive compound feed, a number of biologically active substances (vitamins and amino acids) and improve the digestibility of nutrients for the first time in poultry meat using laser technology there is a real possibility of “transferring” the studied amino acids (methionine, glycine) and all water-soluble vitamins using a laser beam through the skin in the breast area of broiler chickens. The research has been carried out in Belgrankorm-Veliky Novgorod LLC in the Krestetsky district in the Novgorod region with a large-cage housing method of broiler chickens of the cross Hubbard. The duration of broilers rearing was 39 days, 4 recipes of compound feed based on wheat grain, corn, soybeen meal with the inclusion of fish flour, sunflower oil, corn gluten, sunflower meal, meat and bone meal and mineral additives (monocalcium phosphate, lime flour) have been used. For better assimilation of nutrients and biologically active substances by the body amino acids (methionine, glycine) and water-soluble vitamins Undevit, both individually and in combination with them in a ratio of 1:1 (by weight), in the form of powders passed through an infra-red laser beam in a spatial modulator, which were attached to two emitters (simultaneously) of the “Uzor-2K-Super” laser in the chest area have been used. Broilers of the experimental groups ate feed more often and faster than the herdmates of the control group. Air ozonation in the poultry house and broilers has been carried out in a mobile way using the Rios ozonator of the Decont series (mode 3, with a capacity of 20 g/m3 ). Innovative methods of influencing on the body caused the increase in the intensity of metabolic processes, growth and development, fattening and meat traits, and feed conversion in broilers.

Abstract:

OBJECTIVE: To evaluate the viability of ozonated water at diff erent temperatures and ozonation regimes over time. MATERIALS AND METHODS: Th ree experiments were carried out with diff erent ozonation protocols. First experiment analyzed the water ozonated at 55 μg/mL for 5 minutes and kept at room temperature or under refrigeration. In the second experiment, the water was kept only under refrigeration and the concentration of O3 in the device was increased to 70 μg/mL. In this phase, the ozonation process lasted 5 or 10 min utes in two diff erent samples. Th e last experiment generated two samples of ozonated water with a device set at 70 μg/mL with an ozonation time of 10 minutes, but with an even lower refrigerator temperature. Th e analysis of the concentration of this gas was carried out through a colorimetric kit, in periods between 5 and 360 minutes, depending on the experiment. RESULTS: When evaluating the infl uence of temperature, the samples of ozonated water that were kept under refrigeration showed greater stability. Th e ozonation time also increased the viability of the solution. When evaluating an even lower temperature of the refrigerator (close to 0 oC) in an optimized concentration of ozonated water 70 μg/mL, the viability of the solution was observed for a period of 2 hours. CONCLUSIONS: Ozonation with bidistilled water at a temperature close to 0 oC at 70 μg/mL for 10 minutes seems to favor the maintenance of the concentration up to 2 hours with potential antimicrobial properties, enabling the viability for its use for therapeutic purposes.

Abstract:

Clean and safe water is a fundamental requirement for human survival and well-being. The destruction of civilian infrastructure during wars or natural disasters can severely limit access to clean water for the local population, military, rescue workers and volunteers. The objective of the study was the evaluation of the efficiency of fresh water disinfection by electrolytic ozonation. The ozone concentration was measured photometrically by the intensity of the colour change in the reaction with N, N-diethyl-p-phenylenediamine sulfate. The water quality was assessed microbiologically by determining the total microbial count of the samples and by analysing the colour of the bottom of the flasks in which the water samples were stored. The efficiency of ozonation of artesian water in the field was evaluated. Electrolytic ozonation of 500 mL of spring water for two and five minutes produced an aqueous ozone solution with a concentration of 0.74 and 1.72 mg/L, respectively. Electrolytic ozone decomposed slowly and was detected in the samples three days after the water treatment. Ozonation of spring water for 5 and 10 minutes effectively inactivated all natural microorganisms (2.11 log CFU/mL), the water remained sterile and without any colour changes for a month. Water samples ozonated for 2 minutes did not demonstrate any visible changes after a month of storage, however the natural microflora partially recovered. Planktonic microorganisms in the amount of 2.33 log CFU/mL, as well as biofilms on the walls of the flasks, were detected in a month in the control water samples. The colour of the bottom of the control flasks changed to dirty yellow. In the field, ozonation of water for 10 minutes prevented its spoilage even when the recommended treatment volume was increased by 10 times. The obtained results indicate that electrolytic ozonation is an effective method of freshwater disinfection, and portable ozonators can play an important role in emergency water purification in areas of armed conflicts or natural disasters

Abstract:

In this scientific work, the problem of studying the process of destruction of microorganisms in water by an Etro-03 device based on electric corona discharge is considered. In the research, a special Etro-03 ozonator device was developed for clearing water of biological pollutants. Testing of the installation was carried out in order to disinfect surface water in the Kapshagai reservoir. During the research, various harmful microorganisms were found in the composition of the primary water that did not meet the maximum permissible concentration (MPC). For example, coliphages, coli-indices, and the number of microbes in general came across in large numbers. During the technological process, various amounts of ozone (O3) were released into the water, the amount and effective economic indicators of which were determined. In the same way, the effective time of the decontamination process was determined. During the research process, an algorithm of theoretical calculations was developed, and a mathematical model was given to bring 1m3 of surface water as the indicator for which sanitary rules and norms are approved.

Abstract:

The efficiency of ozone as a pre- and post-treatment to UASB treatment was investigated, followed by a study into UASB reactor performance with ozonated wastewater as substrate. Combinations of pre- and/or post-ozonation with UASB treatment gave better results than ozonation or UASB alone and COD reductions of 53.0–98.9% were achieved for treatment of canning and winery wastewaters. A UASB reactor was fed with pre-ozonated cannery wastewater for over 70 d. COD removal improved from between 58.8 and 64.4% to between 85.3 and 91.8% after pre-ozonated substrate feed commenced. Subsequent increases in organic loading rate (OLR) from 2.4 to 3.4 kgCOD m−3.d−1 did not affect reactor performance. By including a final post-ozonation treatment to this UASB effluent a total COD reduction of 99.2% was achieved.

Abstract:

This study aimed to investigate the impact of real MBR effluent pre-ozonation on nanofiltration performances. Nanofiltration experiments were separately run with non-ozonated real MBR effluent, ozonated real MBR effluent and synthetic ionic solution mimicking the ionic composition of the real MBR effluent. The specific UV absorbance and the chemical oxygen demand were monitored during ozonation of real effluent, and the mineralization rate was calculated through the quantitative analysis of dissolved organic carbon. The membrane structure was characterized using SEM on virgin and fouled membrane surfaces and after different cleaning steps. The results confirm the low effect of the ozonation process in terms of organic carbon mineralization. However, the chemical oxygen demand and the specific UV absorbance were decreased by 50% after ozonation, demonstrating the efficiency of ozonation in degrading a specific part of the organic matter fraction. A benefic effect of pre-ozonation was observed, as it limits both fouling and flux decrease. This study shows that the partial mineralization of dissolved and colloidal organic matter by ozonation could have a positive effect on inorganic scaling and decrease severe NF membrane fouling.

Abstract:

<p>Artificial Ozone Generating system needs High Voltage, High Frequency supply. The Ozonator distorts the supply currents and henceforth affect the supply power factor. This paper presents the performance comparison of PWM inverter to Power Factor Corrected (PFC) converter with PWM inverter based High-voltage High-frequency power supply for ozone generator system. The conventional inverter has front end bridge rectifier with smoothing capacitor. It draws non-sinusoidal current from ac mains; as a result input supply has more harmonics and poor power factor. Hence, there is a continuous need for power factor improvement and reduction of line current harmonics. The proposed system has active power factor correction converter which is used to achieve sinusoidal current and improve the supply power factor. The active PFC converter with PWM inverter fed ozone generator generates more ozone output compared to the conventional inverter. Thus the proposed system has less current harmonics and better input power factor compared to the conventional system. The performance of the both inverters are compared and analyzed with the help of simulation results presented in this paper.</p>

Abstract:

Infectious skin diseases are quite common in veterinary medicine. These diseases can be caused by both bacteria and pathogenic fungi. Antimicrobial drugs are usually used for treatment. An alternative to these drugs could be ozonated oils with antibacterial and antifungal properties. Four different ozonated oils (linseed, hemp seed, sunflower, and olive) were tested in order to develop an optimal pharmaceutical form for the treatment of skin infections in animals. Chemical parameters such as acid and acidity value, iodine and peroxide value, viscosity, and infrared spectres were analysed. The ozonation of oils resulted in changes in their chemical composition. The antimicrobial activity of the tested oils was evaluated by determining the minimum inhibitory concentrations and zones of inhibition in agar. After ozonation, the acid content increased in all the tested oils. The highest acidity was found in linseed oil (13.00 ± 0.11 mg KOH/g; 6.1%). Hemp oil, whose acidity was also significant (second only to linseed oil), was the least acidified by ozonation (11.45 ± 0.09 mg KOH/g; 5.75%). After ozonation, the iodine value in oils was significantly reduced (45–93%), and the highest amounts of iodine value remained in linseed (47.50 ± 11.94 g Iodine/100 g oil) and hemp (44.77 ± 1.41 Iodine/100 g oil) oils. The highest number of peroxides after the ozonation of oils was found in sunflower oil (382 ± 9.8 meqO2/kg). It was found that ozonated hemp and linseed oils do not solidify and remain in liquid form when the temperature drops. The results showed a tendency for the reference strains of S. aureus, E. faecalis, and E. coli to have broader zones of inhibition (p < 0.001) than clinical strains. Overall, ozonated linseed oil had the highest antibacterial activity, and ozonated olive oil had the lowest, as determined by both methods. It was found that ozonated linseed oil was the most effective on bacteria, while the most sensitive were S. aureus ATCC 25923, MRSA, and S. pseudointermedius (MIC 13.5 mg/mL, 4.6 mg/mL, and 13.5 mg/mL, respectively, and sterile zones 20.67 ± 0.98 mm, 20.25 ± 0.45 mm, and 18.25 ± 0.45 mm, respectively). The aim and new aspect of this work is the characterisation of selected ozonated vegetable oils, especially hemp oil, according to chemical and antibacterial parameters, in order to select suitable candidates for preclinical and clinical animal studies in the treatment of bacterial or fungal skin infections in terms of safety and efficacy.

Eight structural components of humic substances were ozonated. Mutagenicity was found on TA 100 with and without S9 mix for allthe ozonated components. Aldehydes, ketones and carboxylic acid were identified as the ozonation products from p-hydroxybenzal dehyde. Among these products, acetaldehyde (AA), formaldehyde (FA), glyoxal (GL), glyoxylic acid (GA) and methylglyoxal (MGL) were mutagenic compounds. The quantitative analysis of these mutagenic aldehydes was performed. GL and GA were main mutagenic products. Granular activated carbon (GAC) treatment after ozonation was performed. Most of the mutagenic aldehydes reduced, but only GL increased.

Abstract:

Oil is one of the most popular media for the ozonation process compared to other media such as water or saline methods or direct exposure to blood. Ozonated oil has an advantage over other ozone therapy methods because ozonated oil has an antiseptic activity that is several hundred times higher than ozonated saline. Sumbawa oil is one of the local wisdom products of the Sumbawa tribal community, which is generally used as medicine or massage therapy to heal injuries such as broken bones, tendonitis, bruises, back pain and treatment of various skin wounds. An ozonation process can be carried out to increase the ability of Sumbawa oil to regenerate skin and repair tissue. Ozonation uses a Double Dielectric Barrier Discharge (DDBD) plasma reactor. The DDBD Plasma Reactor is a reactor that can produce ozone gas with very high purity. Pure ozone gas is very well applied in the medical world. This research aims to increase the peroxide levels in Sumbawa oil by ozonation using a Double Dielectric Barrier Discharge (DDBD) Plasma reactor. The flow rates used were 0.1 L/minute, 0.4 L/minute and 0.7 L/minute for 1 hour, 3 hours and 5 hours. The results showed that the peroxide value increased with increasing oxygen flow rate and ozonation time. The highest peroxide value was obtained at a flow rate of 0.7 L/minute for 5 hours, namely 332.03 mg Eq/kg Sumbawa oil. Increased by 282.71 mg Eq/kg; the peroxide figure for Sumbawa oil without ozonation was 49.32 mg Eq/kg.
