Utilization of medium or substrate in the fermentation process is responsible for the product formation. Based on type of the fermentation process and product formed and the medium used, the range of waste materials are produced. Type of the treatment to be applied for effluent depends upon various factors like physical state of the effluent, degree of hazard of pollutant, chemical complexity of the effluent and so on. The simple way of disposing the waste produced is just to dispose them no nearby water-bodies or to convenient open land. But, now it has become almost impossible to practice that measure due to increased population, increased industrial development, awareness on damages caused by pollution made industries in order to treat them prior to their disposal into environment.
