THE USE OF HALLOYSITE TO REDUCE POLLUTIONS CONCENTRATION IN MUNICIPAL WASTEWATER

Abstract

One of the methods of municipal wastewater treatment allows the use of biofilters. The study used a bed filled halloysite. In operation of the bed, depending on the hydraulic load, the concentration of phosphate, ammonium and organic matter was reduced. Highest reduction of the concentration PO43- (89%) and N – NH4+ (81%) in the waste water of the hydraulic load – 0,04 m3/m2h was obtained. The concentration of the organic substrate was reduced by approximately 86%.
