Abstract: Membrane technology has wide range of applications in the textile industry. Various types of dyes and chemicals can be recovered from the textile effluent using this technology and a large proportion of wastewater can be reused. Since textile is one of the major industries in Pakistan and it utilizes a huge volume of water, membrane technology can be an efficient and cost-effective method for treating textile effluents. The problem of membrane fouling is also discussed. The suitability of the technology has been assessed. The approach of employing primary treatment methods followed by Coagulation and Reverse Osmosis through Membranes is being recommended. The effectiveness of various types of membranes available in the world needs to be demonstrated for a specific plant. The results of initial studies performed by Aslam et al. have also been included.

Keywords: Coagulation, Dyes, Membrane Technology, Waste water.
