Full textOur studies have focused on the development of a simple photoreactor hand-made from polymer wastes and recover the coconut shell waste tuning them into activated carbon for the treatment of wastewater. The first part of our study, the photoreactor allowed for the photodegradation of Diuron (abundant in herbicides used in agriculture), under artificial (UV lamp) and natural (sunlight) irradiation. The tests were conducted on two commercial supported catalysts (the Quartzel for Saint-Gobain Quartz and cellulosic support for Ahlstrom). The photodegradation of Diuron kinetics follows a pseudo-first order. The cellulosic support is suitable of our photoreactor even if the Quartzel is more efficient than the cellulosic support. The photodégradation under both two irradiation sources is the same. In order to recover the waste agricultural on Côte d'Ivoire (mainly final waste coconut shell), active carbons were prepared from them by physical activation. We have developed a method that takes into account the cost factor and product performance. Tests of physical and chemical characterizations were performed. Our coal "optimized" has a specific surface of 750 m² per gram about is essentially microporous and contains features acids and bases on its surface. Kinetic studies of adsorption of Diuron showed that the optimized coal has a good affinity with the probe molecule. We have in the last part of our study combined the two processes (photocatalysis followed by adsorption on activated carbon). Preliminary studies on the photo-reactors were carried out. These tests have allowed us to establish the experimental protocol used, which was to make the photodegradation for 90 minutes and then pass the solution through a cartridge of activated carbon prepared by ourselves. A comparative study of three methods was performed and we observed the benefits of coupling TiO2/CA. We could eliminate 10 % of Diuron, and by-products of photodegradation of Diuron remained on the solution. Also technically we can do the process by the day by Photocatalysis and by night by adsorption

Full textThis work is a direct extension of the PhD thesis of Chachuat (2001) on dynamic optimization and optimal control of small size wastewater treatment plants. The objective is to go further by focusing on optimal design and operation of wastewater treatment plants of any size. Thus, in a first part, optimization of small size wastewater treatment plants was studied. Contrary to what has been done so far: (i) the aeration is no longer alternating, but continuous, (ii) the settler is not considered perfect, but its operation is modeled using a series of 10 sedimentation layers, (iii) the optimization approach developed is based on the method of sensitivities implemented wthin the dynamic simulation and optimization software gProms, used throughout this work. The influence of the settler model on the minimization of aeration energy was particularly investigated. In a second part , the large size treatment plants are considered . More specifically, the benchmark model developed by the European network COST was used to describe their operation. A "foreign object" was developed in order to make the simulation and optimization of these plants possible using gProms. The optimisation showed that the aeration energy consumption could be reduced by at least 30 % compared to the current operation of these plants . In a third part, the optimization of the design of the wastewater treatment plant was studied. A superstructure has been defined with several (five) reactors and a settler. All the possibilities of recycling and by-passes between the reactors on the one hand and between the reactors and the settler on the other are considered. The objective was to determine the best structure and the optimal values of the reacter volumes that minimize the net present value while respecting the regulatory constraints. On the other hand, a multi-objective optimization problems of the treatment plant was carried out. It allawed to determine the Pareto set of solutions that minimize the energy consumption (pumping and aeration) and maximize the effluent quality. The fourth and last part of this work focuses on modeling, simulation and optimization of the treatment plant of the city of Verulam in the area of Durban in South Africa. Experimental measurements were carried out on the plant and the ASM1 model was used to describe its operation. An estimability analysis was first performed in order to determine the model parameters that can be estimated from the available experimental measurements . The estimable parameters were then identified using gProms . The identified model was validated and then used to optimize the energy function of this plant

Full textThe stations of purification of waste water, usually known under the name of STEP, produce biological sludge as by-products resulting from the biological treatment. This sludge constitute waste which it is necessary either to develop or to put in discharge. Also there was reason to develop new dies of valorization of this type of waste (sludge) and that through two solutions: the thermal drying and the anaerobic fermentation which are registered in a unit or complementary way in a die of thermal oxidation or agricultural valorization. The two processes make it possible to achieve two aims: the réduction of volume and the fermentation capacity and also offer an interesting natural energy. It is the study of thèse two alternatives which constitute the objective of this research task, thiough the development of a tool of assistance to the design and the diagnoses - Multi Systems - Multi models. The development of the tool is pressed on two shutters. The first shutter is an expérimental study through the implementation of devices control associated with drying and with méthanisation and the second is a theoretical study on the modelling of the processes

Full textA novel process consisting of coupling an absorption step and a biodegradation step, follow by hydrophobic VOC biodegradation in a bioreactor called: "Two-Phase Partitioning Bioreactor" (TPPB), was implemented for the treatment of Volatile Organic Compounds (VOC). Toluene and dichloromethane (DCM) were selected as target molecules. Given their low solubility in an aqueous phase, and in order to effectively deal with these hydrophobic VOC, ionic liquids have been selected as absorbent phase. Twenty-three IL were selected and synthesized in this work; their physico-chemical and biological properties were examined (viscosity, density surface tension, toxicity, biodegradability, stability). Among all IL tested, the [OctIq][NTf2] was selected to be used in the process described in view of its good affinity for toluene (̴ 1365 times higher than water, a Henry’s law constant at 25 ° C of 0. 5 Pa m3 mol-1), with a total lack of biodegradability and a good biocompatibility. The kinetics and toluene biodegradation performances were monitored in the presence of IL in a TPPB using acclimated and non acclimated activated sludge. Tests effectuated in 160-mL flasks were successful, and allowed us to identify key operating parameters to effectuate the scale-up to a 12-L TPPB. This scale-up allowed to confirm the results previously obtained and to optimize the process

Full textThe thesis focused on both experimental and modeling works aiming to investigate the algal bacterial processes in High-Rate Algal Pond (HRAP) system. A pilot HRAP system was built and the impacts of different operational conditions on hydraulic and gas transfer rate of the pilot were investigated. Moreover, optimal inoculation ratio between algae and bacteria (Al-Bac) was also studied. The Al-Bac biomass was theninoculated in the HRAP system for long term assessment of wastewater treatment and nutrient recovery. The HRAP in this study can be applied for secondary treatment application or as a primary step removing rapidly high loads of COD and TKN from centrate wastewater. Experimental results obtained were also employed in calibrating and validating black box and comprehensive algal bacterial models. Both models coulddescribe the system in long term. The former was adequate for giving quick assessment of the system performance as well as sizing application while the latter successfully simulated the results both in long (general) and short (detailed) time scale. A next step should be applying the system in large scale
