Long term operation of a thermophilic anaerobic reactor: process stability and efficiency at decreasing sludge retention time.

Abstract

The aim of this study was to evaluate the performance of thermophilic sludge digestion at decreasing sludge retention time (SRT) and increasing organic loading rate (OLR), in terms of methane production, effluent stabilisation, hygienisation and dewaterability. Focus was put on determining indicators to help prevent process failure. To this end, a lab-scale… (More)
