Theme 3-11-Treatability study on seafood processing industrial wastewater using anaerobic contact filter and rotating biological contactor

Abstract

There are around 50 seafood processing industries located in Tamilnadu and 10 industries near Chennai. All these industries are located near the seacoast and thereby discharging their effluents into the sea and thus polluting the coastal zone and sea. Apart from the major chemical and petrochemical industries, these seafood processing units are the main sources of coastal and sea pollution. The difficulty in managing the problem in this industrial sector may be attributed to number of reasons.

Hence a simple and low-cost effluent treatment system which can be operated and maintained even by semi-skilled manpower seems to be a viable solution for this industrial sector in their environmental management. Hence it was proposed to study the treatability of seafood processing industrial wastewater using anaerobic contact filter and rotating biological contactor which can satisfy the needs. A laboratory scale effluent treatment system was fabricated and a detailed study of the biofilm in the RBC was made and reported.
