HOW DOES A WASTEWATER TREATMENT PLANT WORK?
Wastewater treatment usually takes place in 2 steps: PRIMARY TREATMENT removes 40-50% of the solids. Sanitary sewers carry wastewater from homes and businesses to the treatment plant. Bar screens let water pass, but not trash. The trash is collected and properly disposed of. A grit chamber is a large tank which slows down the flow of water. This allows sand, grit and other heavy solids to settle at the bottom for removal later.
