The primary objectives of filtration in water treatment are to remove remaining impurities and improve the aesthetic quality and safety of the water.
Filtration is a crucial step in the water purification process, typically following sedimentation and coagulation. Its main goals are centered around enhancing clarity, removing residual particles, and further reducing microbial content.
Key Objectives of Water Filtration
Based on common practices in water treatment and the provided information, the main objectives of filtration include:
- Removal of Suspended, Colloidal, and Other Impurities: A key objective is to remove particles that cause turbidity. These include suspended solids, colloidal matter, and other fine impurities that were not effectively removed by previous processes like sedimentation. This step is vital for achieving clear water.
- Reduction of Bacterial Load: Filtration contributes to the overall safety of drinking water by removing bacteria to some extent. While not a substitute for disinfection, filtration physically removes many microorganisms, significantly reducing the microbial count before final treatment.
- Producing Sparkling Clear and Aesthetically Attractive Water: By removing turbidity-causing particles and improving clarity, filtration helps produce water that is visually appealing. This results in water that is sparkling clear and aesthetically attractive to the consumer.
These objectives collectively ensure that water meets quality standards for both appearance and safety before it undergoes final disinfection and distribution.
