Pharmaceutical Wastewater Treatment Using Natural And Chemical Coagulants

Pharmaceutical industrial wastewater is hazardous in nature so it needs to be treatedbefore it is discharged in to any water body or on to soil. This paper, deals with the study of thetreatment of pharmaceutical wastewater using different coagulants. Experimental investigations arecarried with different operational parameters such as pH variation (2-10) and coagulant dosagevariation (1-5g/500ml). Alum, Iron sulphate and Moringa oleifera are used as coagulants. Treatmentis done for turbidity removal and COD reduction. Among all the coagulants studied, the naturalcoagulant Moringa oleifera is observed to be efficient in the treatment of pharmaceutical wastewater
