These include screening, grit removal, and clarification. Raw sewage passes through bar screens which are simply metal rods immersed in the influent flow to separate large objects such as sticks and rags from the water. They are used to protect pumps and other rotating mechanisms further in the treatment process. After the water passes through bar screens, it enters a grit removal system. Here the influent flow is slowed and a mechanical separation of sand and gravel is achieved by systems such as addition of air or inducement of a vortex. Primary clarifiers allow further slowing of the wastewater so that settleable organics precipitate to the bottom while fats, oils, and greases float to the top. These physical processes remove a...
