The textile dye house industries used valuable dyes, which are clearly visible if discharged into public water ways. Thus, their disposal creator both an aesthetic and environmental waste water problem. In this paper study an treatment of textile yarn dyeing waste water using with Reverse Osmosis(RO), textile dyes recovers, waterway pollution is avoided, waste water can be treated new techniques to produce freshwater quality for non-potable uses of reasonable work.

Two methods of treatment like, Dye bath waste water and Wash water. This process of yarn dyeing effluents which are collected separately and following treatment for maximum recycling of recovered waters. Wash water is treated using a sequence of physicochemical and biological unit process, the waste water passed into two stages of RO membrane system which the permeate is reused for processes. The rejects about 8 -12% of the inlet volume is subject to RO for sent to evaporators. Dye bath water after treating, the permeate is used in process for dye bath preparation and reject of about 20 - 25% is sent to multi effect evaporator. The effects of repeated usage on the performance efficiency of the RO studies and the results should a decrease of pH, TSS, BOD, COD and Total Hardness when monitored overtime.
