Screening:
Screening is the initial process in water treatment that is done to remove floating debris, branches, trees, or other large particles suspended in water. It involves the use of screens or mesh filters to physically trap and remove these larger particles from the water.
Process:
The screening process typically involves the following steps:
1. Intake: Water is drawn from the source, such as a river, lake, or reservoir, and directed towards the treatment plant.
2. Bar racks: The water passes through bar racks, which are sets of parallel bars or rods placed at a certain distance. These racks are designed to capture larger debris and prevent them from entering further into the treatment process.
3. Screening: After passing through the bar racks, the water flows through screens or mesh filters. These screens have smaller openings compared to the bar racks, allowing them to capture smaller particles. The screens are typically made of stainless steel or other corrosion-resistant materials.
4. Removal of debris: As the water flows through the screens, any debris, such as leaves, twigs, branches, or other large particles, get trapped on the surface of the screens. The collected debris is periodically removed and disposed of properly.
5. Clean water collection: Once the water passes through the screens, it is considered screened and relatively free from large suspended particles. It is then collected and directed towards subsequent treatment processes, such as coagulation, flocculation, sedimentation, and filtration, to further purify it.
Importance of Screening:
Screening is an essential step in water treatment as it helps to prevent large debris and particles from entering the treatment plant. If these large particles are not removed, they can clog and damage equipment, impede the effectiveness of subsequent treatment processes, and potentially contaminate the water supply. Therefore, screening ensures the proper functioning and efficiency of the water treatment plant while providing cleaner and safer water for consumption.
