Abstract

The objective of this study is to treat contaminated stream by using a UFBR(upflow fixed biofilm reactor) packed with waste- concrete media, This system was tested from June 1999 to January 2000. Over 20.0 , COD removal efficiency did not affected with organic loading rate while, COD removal efficiency decreased about 7% with decrease of temperature from 27.0 to 8.7 , Under 16 , TKN removal efficiency was affected with TKN loading rate. The proposed model apply to mass balance equation of fixed biofilm reactor for predicting effluent was well satisfied with measured value(R^2=0.94).
