The dairy industry involves processing raw milk into products including milk, butter, cheese, yogurt using processes
such as chilling, pasteurization, and homogenization. An experimental investigation was carried out for the treatment of dairy
wastewater using low cost adsorbents such as laterite soil, orange peel, rice husk and groundnut shells. Generally dairy waste
water contains lactose, fat, casein, inorganic salts, detergents, sanitizers etc. These all contribute largely towards their high
biological oxygen demand (BOD), chemical oxygen demand (COD) and oil and grease much higher than the permissible limits,
which affect and disturb the environment. In this paper the wastewater from dairy industry is passing through the vertical stand
which are filled with low cost adsorbents. The use of low cost adsorbents minimizes the hazardous effect which is harmful to the
environment to considerable extent. After conducting the experiments, we found that the COD, BOD, Turbidity and pH of the
dairy waste water
