Abstract

Continuous micro-filtration(CMF) technology was used for reverse osmosis(RO) pretreatment of secondary effluent of dyeing wastewater.The results show the CMF system was stable during operation,and the removal rates of chromaticity and SDI were able to meet the influent quality demand of the RO system.The RO system could effectively remove salinity by over 98%.The water quality of the RO effluent was superior to the tap water,and all the water quality indices were able to meet the demands of reuse of the dyeing technique.
