The Removal of COD and Color from Textile Industry by Chlorine Hypochlorite

Abstract

Industrial wastewaters are played one of the most important roles in environmental pollutions, but discharge these wastewater to environment has always with irreparable damages. The aim of this study was to explore the removal efficiency of COD and color of polyacrylic Textile Industry by Calcium hypochlorite. In this study, this parameter was measured including total Dissolved Total Solids, Turbidity, and pH. Red and blue color product the maximum rate of color. The removal efficiency of COD was about 96 to 98 per cent and for Turbidity were 72 to 71 per cent. Produced Pollution of imported fibers from Belarus, Spain and Japan is 4.47, 3.07 and 6.33 times lower than native fibers. The method of oxidation with chlorine as the easiest, cheapest and most efficient way of preliminary wastewater treatment plant was used in the textile industry polyacrylic. With this technique within COD decrease, the possibility of wastewater treatment with biological treatment in the final stage is provided.
