STUDIES ON PHYICO-CHEMICAL PARAMETERS DURING THE TREATMENT OF WASTE WATER FROM VISCOSE FIBER UNIT BY CHEMICAL COAGULATION

Abstract

In the fiber manufacturing industry the effluent waste water consider the parameter BOD, COD, TDS and pH. The high values of BOD, the untreated textile waste water can cause rapid depletion of dissolved oxygen if it is directly discharged into the surface water sources. The effluents with high levels of COD are toxic to biological life. The high alkalinity and traces of chromium (employed in dyes) adversely affect the aquatic life and also interfere with the biological treatment process. Dissolved solids in effluent may also be harmful to vegetation and restrict its use for agricultural purpose. In this research paper the value of BOD, COD, TDS and adjusted values of pH using the poly aluminum chloride chemical coagulation are presented. The key advantage of PAC using the chemical coagulation is the cost effectiveness and produces larger and more readily settleable flocs than alum. The sludge volume generated by PAC is less than that generated by alum. Results evaluated that the percentage removal of BOD 83.34%, percentage removal of COD 64.04%, percentage removal of TDS 62.97% and values of pH adjusted 6.2 to 6.9.
