Reusability of pre-treatment water obtained via textile wastewater by coagulation and filtration methods in reactive and disperse dyeing

Besides high-water consumption in the textile industry, color, quantity, and variety of chemicals in discharged wastewater draws attention both in terms of environmental and economic aspects. Therefore, efficient, and reliable treatment techniques are needed. In this context, coagulation is a very important step in the treatment of wastewater. In this study, water recovery from textile wastewater taken from different discharge points was investigated by using coagulation and filtration methods. Iron (III) chloride hexahydrate (FeCl3.6H2O) was used as a coagulant. The optimum conditions were determined by studying the effect of different coagulant dosages and pH values. The filtration process was performed using 12-25 µm and
