What is an advantage of presedimentation?

The advantage of presedimentation primarily lies in its ability to remove most of the turbidity before the water reaches the filtration stage. This process involves allowing water to sit in a basin or tank, which causes larger particles and sediments to settle at the bottom due to gravity. By effectively reducing the concentration of suspended solids and turbidity in the water, presedimentation helps to lighten the load on subsequent treatment processes, such as filtration. This results in clearer water entering the filtration system, improving the overall efficacy and lifespan of the filters and contributing to better water quality.

Utilizing presedimentation can also lead to reduced use of coagulants in later stages, enhanced operational efficiency, and lower maintenance costs for water treatment facilities, making it a vital step in the surface water treatment process.
