In this study performance of HEEAD (Hybrid Electrolysis Enhanced Anaerobic Digestion) reactor was analysed and compared with that of EGSB for treating distillery spent-wash. HEEAD is a new type of reactor, in which, an EGSB (Expanded Granular Sludge Blanket) equipped with electrodes. A direct current (D.C) power supply of voltage of 3.6 V to 28.8 V, used to start electrolysis, resulting in the enhancement of biogas liberation. Two reactors, HEEAD and EGSB were run simultaneously, compared in terms of their performance, stability and biogas production. It has been observed that, reactor stability of HEEAD was better even though COD removal was slightly lesser than that of EGSB and biogas generation had increased up to 73% compared to EGSB.
