There are large numbers of bulk drug manufacturing industries and these pharmaceutical industries use large amount of water and generate considerable quantity of waste water. Most of the pharmaceutical industries use batch wise operation. Pharmaceutical industry uses conventional method such as adsorption, aeration, etc. which are not successful in reducing the contaminants as the waste of these industries are very toxic in which bacteria used in aeration cannot survive. So, we need to develop alternate method which can reduce the concentration of contaminants. Pharmaceutical wastewater contains high chemical oxygen demand which cannot be treated using conventional treatment. So, work will be done to find proper advanced treatment which can meet the discharge norms. Further work will be done on factors affecting such as pH, total dissolved solid, TiO2 concentration, etc.

The removal of these contents from the pharmaceutical wastewater has been a big task of the most industrial park wastewater treatment plants.
Currently, society is increasingly more aware of the environmental issues caused by the majority of human activities and has been adopting legislative measures to mitigate, at least partially, the situation. Among all the solutions being considered, the conservation of water resources presents a huge importance since they are limited and indispensable for our lives and the sustainability of the environment. As a result of the rapid human and economic development, excessive use and contamination, water supply has suffered an alarming deterioration in almost every region of the
