Abstract: Effluent generated from the bulk drug industries is attributed with potential risk to the biotic and abiotic environment. The safe disposal of the same requires multiple stages of standard operation and stringent purification. In order to get rid of the ill impacts associated with the unscientific disposal of the bulk drug industry wastewater common effluent treatment plant (CETP) can be installed as a safe, inexpensive, and wholesome treatment unit. The present study, paid minute attention from the primary collection of the potentially hazardous wastewater to the reuse of the tertiary treated reverse osmosis (RO) process permeate. Initially, the collected effluent was stored in a bottom lined collection tank facilitate with a scrubber system and top enclosure to suppress the odour nuisance. Then effluent was immediately taken to the equalization tank and once homogenization got achieved the same was sent to the flocculation unit, where chemical coagulants were added with the effluent and forwarded to the primary clarifiers to remove the flocculants in the form of solid sludge.
