Abstract

The present paper presents results of the study in removal of COD, TSS from domestic sewage water using SBT by uncultured media .Results indicate that % removal COD for four run at different flow rate are 50 % for R1 at flow rate 80 ml/min, 42.3 % for R2 at flow rate 40 ml/min, 46.4 % for R3 at flow rate 35 ml/min, 40 % for R4 at flow rate 30 ml/min. % removal TSS for four run at different flow rate are 60.6 % for R1 at flow rate 80 ml/min , 50 % for R2 at flow rate 40 ml/min , 58.4 % for R3 at flow rate 35 ml/min , 46.6 % for R4 at flow rate 30 ml/min . For 1.03 m deep and 0.2 m diameter bed of bioreactor. Soil biotechnology (SBT) is a system for water renovation which makes use of a formulated media. The process give advantage in terms of applicability for very small to large scale , natural aeration , no moving parts except pumps , no sludge , no odor and all green environment , no pretreatment , high removal efficiency , very low energy requirement.
