Evaluation of the Bio-Kinetics of Cement Kiln Dust In An Upflow Anaerobic Sludge Blanket Reactor for Treatment of Palm Oil Mill Effluent As A Function of Hydraulic Retention Time

Evaluation of the Bio-Kinetics of Cement Kiln Dust In An Upflow Anaerobic Sludge Blanket Reactor for Treatment of Palm Oil Mill Effluent As A Function of Hydraulic Retention Time

In this paper we operated an upflow anaerobic sludge blanket reactor (UASBR) continuously at 35 °C in order to observe the effects of varying the hydraulic retention time (HRT) from 3.5 to 34.5 d and varying the organic loading rate (OLR) from 1.5 to 46 kg COD m−3 d−1. The pH of the digester improve...
