Case analysis of membrane technology in reuse of dyeing effluents

Chunhua Zhang

Abstract

Dyeing wastewater is recycled in the secondary system and further treated by sand filtration,carbon filtration and ion exchange,and the outlet water can be reused or discharged.After an advanced treatment with UF + RO technology,the quality of outlet meets the requirement of reuse in production with removal rates of COD,color and hardness of 94.2%,100% and 100% respectively.
