describe the steps involved in getting clarified water from wastewater?...gud mrng bhidu loag...?
Answers
Answer:
Wastewater is passed through bar screens which remove large objects like rags, sticks, cans, plastic packets, napkins etc.
Water then goes through Grit and Sand removal tank, where sand, grit and pebbles settle down.
Water is then allowed to settle in a tank where solids like faeces (called sludge) settle at the bottom and are removed with a scraper. A skimmer removes the floatable solids like oil and grease. Water so cleared is called clarified water. Sludge is used to produce biogas.
Clarified water is then passed through an aerator tank where air is pumped into the water. It helps aerobic bacteria to grow which decompose organic matter like human waste.
