Influence of hydraulic retention time in a two-phase upflow anaerobic sludge blanket reactor treating textile dyeing effluent using sago effluent as the co-substrate

摘要

Purpose Textile dyeing and sago industries are the most po11uting industries in South India, especia11y in industrial cities like Salem, Tamil Nadu, where textile dyeing and sago industries are clumped together geographica11y. Conventional physicochemical treatment fo11owed by biological processes for the effluent generated from these industries are ineffective, costlier and produce huge quantities of hazardous sludge and harmful by-products which requires further treatment and safe disposal. Hence, the development of an alternative treatment method wi11 become important. The main objective of this investigation is to establish a sustainable biotreatment technology for the treatment of textile dyeing effluent using sago effluent as co-substrate in a two-phase upflow anaerobic sludge blanket (UASB) reactor.
