Abstract: Color, Total Suspended Solids (TSS) and Chemicals are the main form of pollutants in wastewater or industrial effluents. In pharmaceutical effluents the values of these parameters are high and also depict wide variation due to variation in the type of medicines manufactured and raw material utilization. In the present investigation in order to decrease the waste hazards and to restrict resulted effects on the environment, the efficiency of coagulation and flocculation processes have been studied. 3 types of coagulants i.e. aluminium sulphate (alum), ferric chloride, ferrous sulphate along with pre dosing of lime (pH booster) and nanocrystalline (adsorbent) have been used.
