COMPARETIVE STUDY OF MBR AND CAS WASTEWATER TREATMENT SYSTEM
Keywords:
Water treatment, membrane technologyAbstract
This Paper deals with comparison of membrane bioreactors with conventional activated sludge systems for wastewater treatment. There are many water shortage problems currently in India, some of which are more serious public concern over health and the environment combined with the increased requirements for municipalities to reuse wastewater, have created a need for new technologies that can treat wastewater to generate high quality reusable water at low cost. In several of these technologies, membrane technology could make a great contribution since membrane have the ability to produce water of exceptional purity that can be recycled for reuse in a variety of places. In this papers, several aspects of MBR are covered, with an exhaustive over view of its biological performance different configurations and hydraulics of MBR are prevented, with attention given to fouling phenomena and strategies for reducing it.
