Waste Water Treatment by Adsorption and Coagulation

A physicochemical study for the treatment of paper mill wastewater was performed. This effluent is treated with coagulation and adsorption. The composite of wastewater treatment was carried out using Saw Dust Carbon and Rice Husk Carbon as adsorbent and Alum to remove TSS, TDS, color. The paper industry wastewater was treated with different doses of coagulants like alum, at constant contact duration (4 hours) and room temperature (300C). Alum was found to be more effective coagulant and reduce TSS & TDS 58.94% and 59.52% A comparative analysis is done with the two adsorbents saw dust husk and rice husk .It was found that as compare with rice husk by using saw dust husk gives maximum removal (80.88% and 80%),of TSS, TDS and color.
