Comparative study of organic Polyelectrolyte in Municipal wastewater treatment

Abstract

Thecomperative study was carried out for COD removal from municipal wastewater. The two organic polyelectrolyte was prepared on Laboratory scale. The first was Carboxymethyl Chitosan(CM-Chitosan) and second was Carboxymethyl Cellulose(CMCellulose) . Both are the derivative of Chitosan and Cellulose. The Chitosan was extracted from shells of Indian prawn (Fenneropenaeus Indicus) commonly known as white shrimp. The Carboxymethyl Cellulose was prepared from cotton fiber (Gossypium Arboreum). The results shows that COD removed by Carboxymethyl Chitosan between 73.56-77% at optimumDose of 0.4mg/100ml while Carboxymethyl Cellulose removed 43.3-55.3%
