FOOD TECHNOLOGY

Detailed explanation-1: -Primary treatment (also called primary sedimentation) is a sanitation technology that removes suspended solids and floating organic material (called scum) to reduce the suspended solids load for subsequent treatment processes.

Detailed explanation-2: -3.2. Preliminary treatment operations typically include coarse screening, grit removal and, in some cases, comminution of large objects. In grit chambers, the velocity of the water through the chamber is maintained sufficiently high, or air is used, so as to prevent the settling of most organic solids.

Detailed explanation-3: -Preliminary Treatment. The purpose of preliminary treatment is to protect the operation of the wastewater treatment plant. This is achieved by removing from the wastewater any constituents which can clog or damage pumps, or interfere with subsequent treatment processes.

Detailed explanation-4: -The physical process of wastewater treatment begins with screening out large items that have found their way into the sewer system, and if not removed, can damage pumps and impede water flow. A bar screen is usually used to remove large items from the influent and ultimately taken to a landfill.

Detailed explanation-5: -Primary Treatment To remove these solids, the wastewater enters a building called the Headworks and passes through large screen filters which removed this material.
