Secondary Sewage Treatment: This is the next stage of wastewater treatment that uses biological processes to further remove organic matter and pollutants from the water.
Wastewater Treatment Plant: A facility where various processes are carried out to treat and purify wastewater before it can be safely released back into the environment.
