Abstract:

Meat industry generates various wastes such as effluent, emissions and solid wastes that pose environmental and health problems. The effluent released from the meat industries finds its way into the natural water resources and degrade the water quality. The solid wastes of meat industry create a public nuisance by way of foul smell if it is not handled properly. The effluents, as well as solid wastes of meat industries, are possible sources of pathogens that are hazardous to human health. Waste minimization, segregation of wastes and treatment, processing of wastes to make possible recoveries of by-products and the final disposal are the basic steps for containment of pollution from the meat industry. The effluent treatment technologies include primary treatment, secondary treatment and tertiary treatment. Composting, biomehtanation, rendering, incineration and burial are the processes for disposing of the solid wastes generated by meat industries. Appropriate treatment process is selected considering the level of pollution, mode of disposal and the environmental standards. The treatment and processing of meat industry wastes minimize the pollution problems and also give scope for the recovery of by-products such as bone and meat meal, tallow, methane and manure that have commercial values. The meat industries also generate odours that are required to be contained using suitable control devices. The paper seeks to give an overview of the pollution control technologies currently in use for the treatment of effluents and solid wastes, and possible recovery of by-products.

Abstract:

Recently, more and more people have become aware of the need to protect the environment and find new ways to protect our planet from various types of pollution. In this regard, science and technology play an important role in finding new solutions to protect the environment. One innovative development is boron-carbon nanotubes, which contain equal amounts of boron and carbon atoms. Modification of such nanotubes with an amine group would allow to use them for creation of highly sensitive sensor devices, which would help to control the levels of lithium, sodium, potassium in the environment and prevent their negative impact on nature and human health. In this article, a theoretical study of the sensing properties of a functionalized amino-group boron-carbon nanotube of the zig-zag type (6.0) containing equal amounts of carbon and boron is discussed. Such a nanotube could act as an element of a sensor device for environmental protection. The simulation was performed within a molecular cluster model using the DFT computational method, the B3LYP functional, and the 6-31G basis set. It is concluded that the system can be used to detect the presence of alkali metal atoms.

Abstract:

Motor vehicle exhaust is an important cause of atmospheric pollution. Nowadays, mainstream exhaust emission aftertreatment technologies, such as TWC, DOC, SCR, and DPF, usually require sufficient temperature to perform good purification or maintain normal working conditions. Compared with exhaust gas heating technologies such as engine enrichment and fuel injection, electric heating technology can quickly increase the temperature of exhaust gas aftertreatment devices without adverse effects on engine operating conditions. This article introduces the research and progress of electric heating technology combined with traditional aftertreatment devices on major types of vehicles, such as gasoline vehicles, diesel vehicles, motorcycles, and hybrid vehicles, to improve exhaust purification efficiency and its accompanying fuel consumption impact. In addition, the common structure and characteristics of electric heaters, as well as the current status and development trend of electric heating unit technologies such as electric heating power supply are introduced.

Abstract:

Petrol power inevitably finds a very important role in the development of the plant’s economy and technical growth. Inspite of their high thermal efficiency, one cannot ignore the fact about the effect of their exhaust, in the atmosphere. It is a well-known fact that the toxic gases emitted in petrol engines are less than the engines. Due to high cost of petrol, petrol engines are more in use. Anticipating the use of petrol engines, even more in the near future; this system developed can be used to control the toxic gases, coming out of the petrol engines. These toxic gases are harmful not only to the atmosphere, but also to the human & animal race. Objective of this project is to design & fabricate a simple system, where the toxic levels are controlled through chemical reaction to more agreeable level. This system acts itself as a silencer; there is no need to separate the silencer. The whole assembly is fitted in the exhaust pipe; it does not give rise to any complications in assembling it. This system is Very cost effective and more economical. The automobiles play an important role in the transport system. With an increase in population and living standard, the transport vehicles as well as car population is increasing day by day. In addition to this there is a steep increase in the number of two wheelers during the last two decades. All these are increasing exhaust pollution and particularly in metros as density of these vehicles in metros are very high. The main pollutants contributed by I.C. engines are CO, NOX unburned hydrocarbons (HC) and other particulate emissions. Other sources such as Electric power stations, industrial and domestic fuel consumers also add pollution like NOX, SO2 and particulate matters. In addition to this, all fuel burning systems emit CO2 in large quantities and this is more concerned with the Green House Effect, which is going to decide the health of the earth. Lot of efforts is made to reduce the air pollution from petrol and diesel engines and regulations for emission limits are also imposed in the USA and in a few cities of India. An extensive analysis of energy usage and pollution shows that alternative power systems are still a long way behind the conventional ones. Further developments in petrol and diesel engines, combined with improvements in the vehicles, will make fuel consumption reduction of 40% or more in the future cars.This, in turn, will reduce the CO2 emissions, a gas which is responsible for the greenhouse effect.

Abstract:

The article presents the state of solid fuel reserves and their share in the world energy sector. The air pollution caused by the operation of heating devices using solid fuels is a significant problem. In order to improve the air quality, heating device producers take constant measures to improve their products. However, the emission results achieved during an initial test of heating devices in the laboratory may be much worse during operation in real operating conditions. The ways of increasing the efficiency of the boiler by improving its design for combustion in full-layer mode are shown. The results of the testing of the improved КВТС-0.2 hot water boiler is presented and the technical and economic indicators are determined, which indicate an increase in the efficiency of the boiler.

Abstract:

Abstract Several types of vortex separators have been developed during the last 30 years. Their major function has been to provide both flow regulation and settleable solids concentration for the control of combined sewer overflows (CSOs). A variety of opinions have developed regarding the application of these technologies, ranging from overwhelming support to reservations of their effectiveness. The performance of vortex devices depends on the settling velocity distribution of the particles in the wastewater. When correctly installed with other controls in combined sewer or separate stormwater systems, vortex devices can play an important role in the control of pollution from CSO and stormwater discharge. Reliable determination of performance depends principally upon accurate sampling techniques, suspended solids and other pollutant analyses, and the settling velocity distributions of the influent and effluent. Simultaneous flow rate measurement, synchronized to sampling time, is also necessary. This paper discusses design, application and evaluation of swirl/vortex technologies as part of CSO and stormwater pollution control systems.

Abstract:

This paper analyses the correlation between automobile exhaust, PM2.5, and air pollution to explore the rate of contribution of automobile exhaust to PM2.5 pollution and the effect of government regulation on automobile exhaust gas. The results show that the atmosphere is hazy and that car exhaust is the main cause of PM2.5 pollution. This paper divides the governance strategy into two methods: reducing the number of motor vehicles and reducing the emissions capacity of motor vehicles. It also analyses the effects of congestion control on public car travel and establishes a dynamic game model. To strengthen the influence of supervision on enterprises with regard to purifying devices and restrictions, this study also creates a “prisoner’s dilemma” model. The final results of the study show that restriction measures can effectively relieve road pressure. Additionally, congestion costs can alleviate environmental pressure, but it is difficult to determine the costs, and the difficulty of implementation increases. Increasing enterprises’ installation of purifying devices is not advisable or desirable in the short term. Finally, the paper offers some suggestions for the maintenance of the atmospheric environment and the management of automobile exhaust: (1) improve the national green transport system and environmental protection awareness; (2) advocate public transport as a mode of travel; and (3) reduce the use of buses and popularize new energy vehicles.

Abstract:

Plastic pollution has emerged as a growing concern worldwide. In particular, the most abundant plastic debris, microplastics, has necessitated the development of rapid and effective identification methods to track down the stages and evidence of the pollution. In this paper, we combine low-cost plastic staining technologies using Nile Red with the continuous feature offered by microfluidics to propose a low-cost 3D printed device for the identification of microplastics. It is observed that the microfluidic devices indicate comparable staining and identification performance compared to conventional Nile Red staining processes while offering the advantages of continuous recognition for long-term environmental monitoring. The results also show that concentration, temperature, and residency time possess strong effects on the identification performance. Finally, various microplastics have been applied to further demonstrate the effectiveness of the proposed devices. It is found that, among different types of microplastics, non-spherical microplastics show the maximal fluorescence level. Meanwhile, natural fibers indicate better staining quality when compared to synthetic ones.

Full text

Abstract:

Air pollution is caused by the presence of polluting elements. Ozone (O3), carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter (PM) are the most controlled gasses because they can be released into the atmosphere naturally or as a result of human activity, which affects air quality and causes disease and premature death in exposed people. Depending on the substance being measured, ambient air monitors have different types of air quality sensors. In recent years, there has been a growing interest in designing drones as mobile sensors for monitoring air pollution. Therefore, the objective of this paper is to provide a comprehensive patent review to gain insight into the proprietary technologies currently used in drones used to monitor outdoor air pollution. Patent searches were conducted using three different patent search engines: Google Patents, WIPO’s Patentscope, and the United States Patent and Trademark Office (USPTO). The analysis of each patent consists of extracting data that supply information regarding the type of drone, sensor, or equipment for measuring PM, the lack or presence of a cyclone separator, and the ability to process the turbulence generated by the drone’s propellers. A total of 1473 patent documents were retrieved using the search engine. However, only 13 met the inclusion criteria, including patent documents reporting drone designs for outdoor air pollution monitoring. Therefore, was found that most patents fall under class G01N (measurement; testing) according to the International Patents Classification, where the most common sensors and devices are infrared or visible light cameras, cleaning devices, and GPS tracking devices. The most common tasks performed by drones are air pollution monitoring, assessment, and control. These categories cover different aspects of the air pollution management cycle and are essential to effectively address this environmental problem.

Abstract:

E-waste in simple words is the waste that is generated from devices like mobile phones, computers, ACs, fridges etc. The different types of waste are the outcome of our daily or industrial activities. E-waste is generated when the devices we use in our daily lives are broken or worn out of use they are either thrown in the garbage or sold at the value of it, which ultimately results in the accumulation of unwanted electronic waste. The paper discusses the generation of mounting quantities of e-waste leading to increased threats to the environment due to multiple reasons such as industrialization, urbanization and changes in the pattern of life, which accompany the process of economic growth. In recent years, technologies have been developed that are triggering a substantial quantity of energy and waste from the devices posing a threat concerning e-waste for its safe disposal. The paper discusses in depth the methods of how western countries are responsible for the accumulation of E-waste in the South Asian region in the name of used goods. The authors explain in detail what steps can be procured to prevent such accretion, moreover emphasizing the methods inculcated by various countries to deal with such type of waste. The authors have attempted to suggest steps, with the help of which the recycling of the e-waste generated can be made sure along with the methods to control the generation of e-waste simultaneously.

Abstract:

Sanitary sewage yields the basic and most important pollution load diverted to receiving waters during combined sewer overflow (CSO). To reduce overflow pollution loads, it is proposed to store waste water in sanitary sewage detention tanks (SST). For high efficiency those SSTs should be filled and emptied by pumps or gates, operated by control devices. Control strategies have to be worked out depending on different situations and parameters (catchment, rain and flow characteristics).

Abstract:

China’s agricultural facilities are developing rapidly and are mainly operated through household contracting. Due to a lack of suitable variable-rate fertilization devices, manual and blind fertilization still widely exists, resulting in fertilizer waste and environmental pollution. Meanwhile, existing fertilization devices cannot simultaneously meet the needs of different fertilization methods for crop cultivation, increasing the cost of mechanized fertilization. This study developed a lightweight dual-mode automatic variable-rate fertilization device and control system for strip fertilization and spreading fertilization. The least squares method was used to analyze the amount of fertilizer discharged per second at different volumes and rotational speeds of the fertilization device. The quadratic polynomial model fits well, with determination coefficients greater than 0.99. The automatic variable strip fertilization and spreading fertilization control models were established. Experiments with strip fertilization and spreading fertilization were carried out. The results of strip fertilization experiments show that the maximum relative error (Re) for granular nitrogen fertilizer (NF) was 6.81%, compound fertilizer (CF) was 6.2%, organic compound fertilizer (OCF) was 6.83%, and the maximum coefficient of variation (Cv) of uniformity was 8.91%. The results of spreading fertilization experiments show that the maximum Re of granular NF was 7.31%, granular CF was 6.76%, granular OCF was 7.43%, the Cv of lateral uniformity was 9.88%, and the Cv of total uniformity was 14.17%. The developed fertilization device and control system can meet the needs of different fertilization amounts, types, and methods for facility crop cultivation at different stages. This study’s results can provide a theoretical basis and technical support for designing and optimizing multifunctional precision variable-rate fertilization devices and control systems.

Abstract:

Cement plants are crucial industrial entities that supply cement for various applications, including the construction of buildings and bridges. While these plants play a vital role in infrastructure development, they are also recognized as significant sources of environmental pollution. To mitigate air pollution, Electrostatic Precipitators (ESPs) are employed, capable of reducing air pollution by approximately 99.99%. Consequently, ESPs warrant in-depth study, and development. This project focuses on investigating, and developing a monitoring, and control system for ESPs utilizing intelligent devices. The initial step involved deriving a mathematical model based on input/output data from the critical unit, the transformer/rectifier (T/R set). The Grey Wolf Optimization algorithm was employed to determine the optimal parameters (Kp=988, Ki=37.7, Kd=88.5) for the PID controller using the MATLAB package.

Abstract:

The retention of suspended solids, particles and heavy metals in different grassed swales during rain events and snowmelt is discussed. The experimental results derived from investigations performed in existing grassed swales in the Luleå region, Northern Sweden. During high pollutant loading rates, grassed swales retain significant amounts of pollutants, mainly due to sedimentation of particulate matter. Low to moderate removal efficiencies could be expected for heavy metals, especially metals in solution (i.e. the dissolved phase). When grassed swales receive urban runoff with low pollutant concentrations, they may release rather than retain pollutants. Swales are important snow deposit areas in the city and particle bound pollutants do to a large extent remain in the swale after snowmelt. However, dissolved pollutants (i.e. dissolved heavy metals) are likely to escape the swale with the melt water. Grassed swales may be regarded as facilities that even out the peaks in pollutant loads without being capable of producing consistent high removal rates. This suggests that swales should be considered as primary treatment devices. Possible design parameters for grassed swales are mean hydraulic detention time, surface loading rate or specific swale area.

Abstract:

Abstract Digital information is the fuel of the new economy. But like the old economy’s carbon fuel, it also pollutes. Harmful “data emissions” are leaked into the digital ecosystem, disrupting social institutions and public interests. This article develops a novel framework—data pollution—to rethink the harms the data economy creates and the way they have to be regulated. It argues that social intervention should focus on the external harms from collection and misuse of personal data. The article challenges the hegemony of the prevailing view—that the injuries from digital data enterprise are exclusively private. That view has led lawmakers to focus solely on privacy protection as the regulatory objective. The article claims, instead, that a central problem in the digital economy has been largely ignored: how the information given by people affects others, and how it undermines and degrades public goods and interests. The data pollution concept offers a novel perspective why existing regulatory tools—torts, contracts, and disclosure law—are ineffective, mirroring their historical futility in curbing the harms from industrial pollution. The data pollution framework also opens up a rich roadmap for new regulatory devices—“an environmental law for data protection”—which focuses on controlling these external effects. The article examines how the tools used to control industrial pollution—production restrictions, carbon tax, and emissions liability—could be adapted to govern data pollution.

Abstract:

Due to the rapid advancement in power electronic devices in recent years, there is a fast growth of non-linear loads in distribution networks (DNs). These non-linear loads can cause harmonic pollution in the networks. The harmonic pollution is low, and the resonance problem is absent in distribution static synchronous compensators (D-STATCOM), which is the not case in traditional compensating devices such as capacitors. The power quality issue can be enhanced in DNs with the interfacing of D-STATCOM devices. A novel three-phase harmonic power flow algorithm (HPFA) for unbalanced radial distribution networks (URDN) with the existence of linear and non-linear loads and the integration of a D-STATCOM device is presented in this paper. The bus number matrix (BNM) and branch number matrix (BRNM) are developed in this paper by exploiting the radial topology in DNs. These matrices make the development of HPFA simple. Without D-STATCOM integration, the accuracy of the fundamental power flow solution and harmonic power flow solution are tested on IEEE−13 bus URDN, and the results are found to be precise with the existing work. Test studies are conducted on the IEEE−13 bus and the IEEE−34 bus URDN with interfacing D-STATCOM devices, and the results show that the fundamental r.m.s voltage profile is improved and the fundamental harmonic power loss and total harmonic distortion (THD) are reduced.

Abstract:

Coal-fired power plant is one of the largest sources of mercury emitted into the atmosphere artificially. In the paper, more intensive investigations were performed in 27 power plants for observing distribution of mercury at all the effluents. Mass balance of mercury was figured out from the emission data and analysis results of mercury at all the in- and out-streams. The results show that, concentrations of mercury emitted from stack gas equipped with air pollution control devices (APCDs) range between 0.6734 and 14.4312μg/m3 with coal mercury content lower than 0.20mg/kg. FGD gypsum mercury is about 2~10 times as that of in coal. The average mercury removal efficiency by ESP is only about 29.36% while ESP +wFGD and dry-FGD+FF about 68.72% and 81.51% separately. Therefore, it is necessary to enhance the existing APCDs, wash and mix coal to Hg co-removal for coal-fired power plants.

Abstract:

A terminal for remote control of charging stations for electric vehicles (EV) powered by renewable energy has been presented in this paper. This terminal enables remote control of EV chargers, smart batteries, smart electricity meters, fiscal cash registers (FCR), as well as remote control of renewable energy sources and other devices within the station. This terminal also makes charging stations more accessible to electric vehicles users, to electricity distribution companies, to electricity suppliers, to tax administrations, and finally to users and owners of charging stations. Therefore, communication and control with all these devices and systems is integrated in one device. Realization of hardware and software of such a terminal has also been described in this paper. The net result of development and commercialization of terminals would encourage an increase in the use of electric vehicles powered by energy from renewable sources, which would cause a decrease in the level of air pollution and all negative effects it causes in the future. Different categories of this device are considered. Moreover, although it is a device with embedded software, a very advanced method was used, that is, a model-driven development method, which enables fast and more efficient development and maintenance of the device. The results of the application of this method to the terminal for remote control of fiscal cash registers are provided. They were compared with the results of the development of the terminal for remote control of smart meters without applying this method. A simulation of the development of the terminal for remote control of the station is also provided. The presented method can be used in the future for faster and better-quality development of embedded software.

Abstract:

A device and method for the constant pressure regulation of microdroplet PCR in microfluidic chips are developed to optimize for the microdroplet movement, fragmentation, and bubble generation in microfluidic chips. In the developed device, an air source device is adopted to regulate the pressure in the chip, such that microdroplet generation and PCR amplification without bubbles can be achieved. In 3 min, the sample in 20 μL will be distributed into nearly 50,000 water-in-oil droplets exhibiting a diameter of about 87 μm, and the microdroplet will be subjected to a close arrangement in the chip without air bubbles. The device and chip are adopted to quantitatively detect human genes. As indicated by the experimental results, a good linear relationship exists between the detection signal and DNA concentration ranging from 101 to 105 copies/μL (R2 = 0.999). The microdroplet PCR devices based on constant pressure regulation chips exhibit a wide variety of advantages (e.g., achieving high pollution resistance, microdroplet fragmentation and integration avoidance, reducing human interference, and standardizing results). Thus, microdroplet PCR devices based on constant pressure regulation chips have promising applications for nucleic acid quantification.
