Industrial wastewater is one of the important pollution sources in the pollution of the water environment. During the last century a huge amount of industrial wastewater was discharged into rivers, lakes and local areas. Dumping of untreated effluent directly into drainage system by industries located into industrial area which may contaminate ground water table or any water body. The industrial wastewater which is dangerous for human life and irrigation purpose. So it requires to treat and then it should be used for irrigation purpose. Therefore waste water should be treated and then can be used for agricultural purpose.

With proper design and operation, Aerated lagoon can deliver effluents that meet limits of standard parameters. For wastewater treatment, such as activated sludge and tertiary nutrient

Removal are too costly to provide a satisfactory solution for the increasing wastewater problems in developing regions. These technologies do not allow for re-use of valuable energy and nutrients contained in the wastewater. Aerated lagoons are commonly used in the pulp and paper industry for aerobic biological effluent treatment. Basically, an aerated lagoon is a large aerated volume through which the effluent passes during a number of days. Microorganisms thriving in the lagoon convert organic matter in the effluent to carbon dioxide, water and biomass. The effluent treated in a lagoon is led through a secondary clarifier to remove Bio-sludge produced in the lagoon before being discharged.
