Abstract

The study was conducted to identify bio-product that could be used for treatment of biogas effluent at household scale. In the experimental condition, the treatments were arranged in a completely randomized design including the control treatment (without bio-product) and five bio-products including EmTech Green, BioEm, Emc, Jumbo A, and EmTech BKS. The results showed that the treatment efficiency of total suspended solids (TSS), chemical oxygen demand (COD), total Kjeldahl nitrogen (TKN), total phosphorus (TP), total coliform, and E.coli of the five tested bio-products were in the range of 28 - 97.3%. The treatment efficiency of BioEm and Emc was significantly higher than that of the control and the other bio-products of EmTech Green, Jumbo A, and EmTech BKS. At household scale, BioEm and Emc had treatment efficiency of TSS, COD, TKN, TP, and total coliform from 55.4 to 86.9%.
