How do microorganisms help in sewage treatment plant?
Microorganisms breaks down the chemical and biological waste present in the sewage, digesting the organic matter present in it. They feed on the organic matter and releases an enzyme which helps in its degradation removing the organic matter from the sewage.
Where do the microorganisms used in wastewater treatment come from?
Activated sludge is a mixture of microorganisms that come in contact with and digest biodegradable materials (food) from wastewater. Once most of the material is removed from the wastewater, microorganisms form floc and settle out as sludge.
How do microorganisms break down waste?
