The wastewater then undergoes a biological process known as activated sludge process, which uses natural occurring micro-organisms to break down dissolved and suspended organic solids. The settled wastewater then enters aeration tanks where air is blown into the water to provide oxygen promoting the growth of microorganisms. These microorganisms then consume the organic pollutants and nutrients in the wastewater. From the aeration tanks the mixture of wastewater and microorganisms is moved to a secondary sedimentation tank where the biomass settles to the bottom of the tank and is concentrated as sludge.
