Abstract :Pollutants must be removed from the water to protect the environment and public health. When water is used by the industry, the water becomes contaminated with pollutants. If left untreated, these pollutants would negatively affect the water and environment. Treatment of wastewater is an essential process that prevents contamination and the destruction of waterways, drinking water resources and natural water resources. Waterborne diseases are also eliminated through proper wastewater treatment. Wastewater is approximately ninety-nine percent water and only one percent solids. The removal of these solids and disinfection of the water before discharge is the basic concept of wastewater treatment. Zero discharge plant has many advantages in comparison with the older methods used for treatment. One of the pharmaceutical unit generates effluents, it can discharge effluents into the CETP (Common Effluent Treatment Plant) per day. So it has been decided to treat all the effluents in their plant itself and recycle maximum water by installing zero discharge units. Treatment of effluents is a must as per MPCB (Maharashtra State Pollution Control Board) norms. Effluent to comply the norms it has been incorporated of MPCB a zero discharge unit which recycles all the water from waste effluents and discards only solid wastes. In this paper the detailed study on zero discharge system of Pharmaceutical Plant has been done. It is observed that by implementing zero discharge concept pharmaceutical plant is able to utilize all recovered water in its utility unit.
