1) First the wastewater passes through the screens of vertical bars to remove solid waste like plastic bags , cans etc.
2) The water is then passed through settling tanks known as grit chambers. It's speed is reduced so that solids such as sand,silt and
gravel settle down and are removed.
3) After this, the wastewater passes into a sedimentation tank called a clarifier, in which organic material settle down and are removed with a scraper. This is called sludge. floating material like oil and grease are removed with the help of skimmer.
4) Next air is pumped through the clarified water in an aeration tank. This allows aerobic bacteria to grow and consume organic contaminants such as faeces, food waste and soap still left in the water.
