ABSTRACT

The present study deals with the absorption of chloride from electroplating industry effluent using bacteria. Physico –chemical characteristics such as pH, electrical conductivity, total solids, total dissolved solids, suspended solids, hardness, sodium, potassium, calcium, sulphate, chloride, dissolved oxygen, BOD, COD and zinc were estimated. Different concentration (0.2,0.4,0.6,0.8 & 1.0 ml) of bacterial species such as Pseudomonas aeruginosa, Pseudomonas flourescens, Bacillus subtilis and Bacillus magaterium along with the electroplating industry effluent was incubated in a shaker for 18, 20, 22 and 24 hours. Among the four bacterial species Pseudomonas fluroescens had higher capacity of chloride absorption.
