What is the main benefit of sedimentation in the raw water treatment process?

The main benefit of sedimentation in the raw water treatment process is that it reduces filter load by removing turbidity. During sedimentation, suspended solids and particulate matter settle out of the water due to gravity. This process helps clarify the water by significantly reducing the amount of turbidity, which is crucial for effective filtration.

By lowering the turbidity levels before the water reaches the filtration stage, sedimentation minimizes the workload on filters, enhancing their efficiency and extending their lifespan. It results in less frequent backwashing and maintenance, leading to cost savings and improved performance of the overall water treatment system. This step is critical as it prepares the water for subsequent treatment stages, ensuring higher quality and safety for end-users.
