Abstract
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.

Summary
The object of research The object of research is the process of wastewater treatment, in particular wastewater purification from nitrogen and phosphorous compounds using bioconversion. Problem description Energy consumption is increasing constantly [1]. Progress in means of combustion products purification does not keep up with the increasing amount of harmful substances formed during energy production. If humanity continues to consume fossil fuels at the current level (despite the steady increase in population), known oil and gas reserves may be depleted in the 2050s–2060s. The search for alternative fuels undoubtedly comes to the fore today. Bioconversion is the process of converting one chemical compound into another with the required chemical characteristics, with the participation of microorganisms.
