ABSTRACT
In this study acrylic water base color was removed from synthetic wastewater using coagulation process. Experiments were conducted on the sample containing 100 mg/L and 400 mg/L of acrylic water base color. Destruction of color by means of coagulation/flocculation techniques using ferrous sulfate, alum, lime and polyelectrolyte [cationic, anionic and non ionic].The study was performed in a systematic approach searching optimum values of alum and FeSO[4] concentration, pH and temperature. All the experiments were run in a laboratory scale. The obtained results show that treatment with alum and ferrous sulfate alone proved to be very effective in removing the color [> 99%] and part of COD [60-70%] from aqueous solution. Lime alone did not significant change on COD and color removal
