The work was carried out keeping in mind reduction of environmental pollution.The scope of coauthors in completion of my work is tremendous and inspiring.Dairy is called as wet industry and one major nutrient production industry. Waste is generated from various stages during milk processing. Aeration is one widely used process for its treatment and through this work efficient aeration for treatment was found out. Natural coagulant Moringa oriefera was found best in reduction of color and turbidity of dairy wastewater as in having no toxic effect. Comparison between bacterial treatment and aspergillus was carried out and bacteria was found to be effecient.Overall work has scope for further studied which can be carried on on dairy wastewater using microbes and aeration or natural coagulant. I feel proud to be a part in maintaining a clean environment for the future generation.
