Intellectualized Control System for Anaerobic Bioconversion of Liquid Organic Waste

The use of methods for the biological conversion of organic waste with the production of biogas while solving environmental issues from pollution is an urgent task. The aim of this work is the development of intellectualized control system of parameters of anaerobic bioconversion of organic waste liquid, including parameters of heating supply system of a biogas plant with optimization of the combustion process of biogas, while using the method of optimization of the anaerobic bioconversion of organic waste due to the multiple supply substrate to the bioreactor, ensuring the efficiency and stability of anaerobic bioconversion of organic matter. The developed system allows optimizing the process of biogas combustion with obtaining the heat carrier in the required quantity and quality while minimizing emissions of biogas combustion. Maintaining the optimal rate of supply of the daily dose of the substrate in the bioreactor allows to increase the resistance to organic matter overload; to increase resistance to ammonium nitrogen overloads; to reduce pH fluctuations in the bioreactor.

Production of Bioethanol from a Local Natural Resource

In this work, we have studied the possibility of energy recovery from the fruit wastes of Adrar University as a substrate for the production of bioethanol by anaerobic bioconversion in the presence of the yeast Saccharomyces cervisiae. During this study, we have prepared a black must in which a mass of 100g of the substrate used is placed in 1 L of tap water, after fermentation at 30°C for 72 h, the solution is filtered, then centrifuged and then a fractional distillation operation was carried out in order to purify the ethanol produced and we recovered a volume of 35 ml of the bioethanol. Finally, we applied an inflammation test on the bioethanol obtained which gives a positive result. The result shows that waste from the local natural resource has great potential for the production of ethanol
