Abstract

The objective of this work was to comparatively investigate the performance of two anaerobic waste water treatment reactors namely UASB and fluidized Bed Reactor (FBR). Two lab scale models were erected and experiments were carried on both the reactors for different substrate concentration of COD 16800mg/L and 2880mg/L for UASB and FBR respectively. Effect of HRT on degradation of organic matter was studied through estimating COD at regular time intervals, COD removal rates for FBR and UASB were found to be 108mg/L/ day and 231mg/L/day respectively, The COD removal for UASB and FBR was 60% and 57% of the initial value respectively.
