The object of research: the process of wastewater treatment using bioconversion for subsequent motor fuel production. Investigated problem: improving the efficiency of bioconversion process for biofuel production with simultaneous wastewater treatment by removing nitrogen and phosphorous compounds. The main scientific results: providing the possibility of biofuel production with energy and economic inefficiency. It is done by combining the process of motor biofuel production with the process of treating wastewater from biogenic elements makes it perspective for commercial use. Traditional technology for the production of motor biofuels from microalgae includes cultivation, harvesting, dehydration and drying of biomass, extraction of oils from them and subsequent production of methyl esters and glycerol. Such technology is often not economically effective. It requires significant amount of energy for carrying out all necessary processes. In addition, it requires significant expenditures of water and nutrients. The use of nutrient-rich wastewater as a culture medium for the cultivation of microalgae allows not only to reduce costs, but also to purify wastewater from nitrogen and phosphorus compounds, which makes this process economically effective. The area of practical use of the research results: Sewage and gray water treatment plants. Industrial and agricultural effluents treatment plants. Different types of enterprises, which have wastewater enriched with nitrogen and phosphorous compounds. Innovative technological product: The technology of microalgae cultivation using wastewater as a culture medium. The technology allows effectively purifying used wastewaters from nitrogen and phosphorous compounds with no waste at the end. Scope of the innovative technological product: Improved technology of motor biofuel production with simultaneous wastewater purification, which is economically effective and environmentally safe.

Tеxtile wastewater contains a variety of contaminants that are known to be hazardous. Synthetic dyes are one of the hazardous pollutants in the textile industry that are resistant to the photo/bio dеgradation. They cannot be dеstroyed under conventional wastewater treatment. This document presents a review on the electrochemical treatment of wastеwater containing synthetic organic dyes by anodic oxidation for environmental protection. The mechanisms of еlectrochemical oxidation in anodic oxidation processes are well explained. A largе number of electrodes have been tested by this method. Therefore, this papеr aims to summarize and discuss the most important and rеcent results available in the literature on anode application for the rеmoval of synthetic dyestuffs. Finally, the prospects of the process for futurе research are suggested.

The article has an aim to describe experience of Moscow in the field of solid bio-fuel production at wastewater treatment plants (WWTP). Brief assessment of solid biofuel production technology at biological treatment facilities of domestic and mixed sewage (wastewater sludge as a fuel resource) shows its significant potential from the economic, environmental and social points of view that will ensure the sustainable development of the area (cities, regions) of application. Solid biofuel production is a technological stage of sludge treatment at wastewater treatment plants aimed at reducing the sludge mass and changing their physical and mechanical properties for its further use at as a fuel component on condensing and thermal power plants or as alternative fuel for cement production and energy supplements for burning of solid domestic waste. The technology of solid biofuel production is based on removing moisture of wastewater sludge in drying machines. The solid fuel facilities capacity lies in the range of 1 to 130 tons per day, when the entire amount sludge is exposed to drying (effluent humidity of sludge is 10%), or 1 to 400 tons per day when the sludge is partially dried and afterwards is mixed with the initial sludge (effluent humidity of sludge is 40%).
