N2  - Several physico-chemical processes were studied in treating the high color, low BOD textile wastewater from a synthetic textile factory using polyester and rayon as raw materials. Among these  processes are series filtration using shredded coconut husk fiber and burnt rice husk as filter media, granular and/or powdered activated carbon adsorptions, and chemical coagulation. Both series  filtration and carbon adsorption were found ineffective due to poor color removal efficiency and short operational time. Chemical  coagulation using alum as coagulant was found capable of removing 90% of color and 50% of COD at pH of 6.0 and dosage of 200 mg/l for a representative composite sample. 0.4 mg/l of Sanpolymer A510 was used as a coagulation aid to accelerate the settling of the precipitants. A. survey of the in-plant wastewater and an appraisal of-different treatment systems for the generated wastewaters was also made as part of the study.
