Ecological Systems and Devices Annotation << Back The intensification of growth of active sludge microorganisms of constructions for the biological purification Колотова О.В., Владимцева И.В., Голованчиков А.Б., Федотова Л.В. The air ions of positive and negative polarities intensify growth of the microorganism biomass obtained from active sludge of constructions for the biological purification. As a result of calculations for industrial aerotank and the biofilter an ionizer in the constructions of purifying constructions allows to reduce the cost price of sewage purification, results in reduction of capital outlays by building of purifying constructions and decrease of the alienable areas.
