Recent Advances in Bio - chemical Reactors for Treatment of Wastewater

Abstract

The importance of the treatment of wastewater in view of its potential health hazard has been highlighted. Typical compositions of wastewater from municipality as well as a few industries have been presented. The principle of working of the traditional free - cultured bioreactors and their performance constraints have been outlined. The relative advantages of various modern bio reactors working on immobilization technique have been projected. A comparative picture with respect to various modern bioreactors has been presented and the uniqueness of the fluidized and semifluidized bed bioreactors in the treatment of wastewater has been emphasized.
