Anaerobic-aerobic wastewater treatment technology by nitrogen compounds are proposed and investigated. In it provides use of immobilized on a nylon fibrous support of microorganisms and provides a high cleaning effect of ammonium nitrogen – 96-98,6%, the concentration of nitrate and nitrite in the treated water is in accordance with discharge into natural water. As a result produced a small amount of sewage sludge – 0.2-0.4 g/(m3∙d) with high mineral part – 38-48%.

Wastewater of food industries contains high concentrations of nitrogen compounds mainly in the form of ammonium nitrogen The effective anaerobic-aerobic wastewater treatment technology from nitrogen compounds of malt industry wastewater is proposed. Biotechnology is suggesting with consistently jointed anaerobic and aerobic bioreactors with сcarrier for microorganisms immobilization. Design and process parameters of laboratory installation are makes. This technology allows to reach high levels wastewater treatment from organic (86-95%) and nitrogen compounds (81-93%).
