The book is a study is devoted to develop proposals & solutions can be applied to treat pollution problem produced by the textile industries, also to recycle water reducing the water resource shortage problem, the book also deals with the evaluation of the operational properties of the locally produced membrane system from the Laboratory of Research and Membrane Unit at the University of Technology / Baghdad (NF and UF membrane) to remove the dyes (disperse-Terasil Navy Blue, acidic- Red, reactive- Cibacron Navy C-B Blue) from the wastewater of AL- Kut textile factory which are widely used dyes in Wasit Governorate factories / Iraq. The book provides good understanding of the effectiveness of membrane systems (NF and UF) in rejecting these dyes under different conditions (pressure, temperature, Anti-scale acid). The experimental results showed that the removal ratio of both (dye &COD) using UF and NF membranes increases with increasing operational pressure, and also the type of reactive dye is the most intense and concentrated
