Abstract

One of the environmental aspects of high impact in dairy industries is the discharge of wastewaters, because of contaminating organic matter as well as the substantial generation of effluents. In the present study, a biofiltration of effluents from a dairy industry in San Miguel de Nono (Ecuador) with a pollution load of 10.000 mg/L in terms of chemical oxygen demand and turbidity of 799 NTU was implemented. The system with a capacity of 55 L per batch consisted of three biofilters in series and activated zeolite assisted clarification. Organic degradation reached 98,9%; turbidity removal was 95,2%, 94,4% of nitrogen and 89,1% of phosphorus. The presence of milk fat did not decrease the efficiency of the biofiltration but increased the removal of suspended matter and pH neutralisation in the clarification. The optimal operating time was 6 hours under aerobic conditions.
