STARTUP CHARACTERISTICS OF HUASB AND UASB REACTORS FOR TREATING TAPIOCA-BASED STARCH INDUSTRIAL WASTE STREAM: A COMPARISON

摘要

In this paper, start-up characteristics of HUASB and UASB reactors for treating tapioca-based starch industrial waste stream has been studied under identical conditions of operation. Various effluent characteristics (pH, alkalinity, VFA, VSS, COD removal -%, bio-gas) were studied until the attainment of steady state. It is found that from an overall assessment the HUASB reactor has performed better than the UASB reactor during the start-up process, for treating the tapioca-based starch industrial waste stream.
