Abstract: The primary goal of this research is to evaluate the treatment of dairy effluent from a Coimbatore industry sector utilising algae bioreactor techniques. The activated sludge process is a biological wastewater treatment process for treating industrial wastewater for reducing solid particles and simultaneously treating dairy wastewater under aerobic conditions. In this present study, an aeration tank is designed and fabricated for the treatment of wastewater and sludge production by inoculating green algae. The algae bioreactor is operated continuously for 30 days by supplying oxygen. The wastewater characteristics are tested for their concentration to find the removal efficiency of the aerobic tank. This study attempts to reduce the pollutant concentration and CO2 emission from wastewater as well as produce fertilisers from this treatment. This method of treatment is sustainable and eco-friendly.
