Ensuring a clean and safe water supply is crucial, and one effective method used in water treatment plants involves a series of carefully designed steps:
- Raw Water Intake: Drawing water from a reservoir provides a steady source for treatment. - Aeration: Passing water through an aerator helps remove dissolved gases and oxidize metals like iron and manganese.
- Chemical Addition: Adding alum acts as a coagulant, binding small particles together. - Flocculation and Sedimentation: Water is gently mixed to form flocs, allowing clearer water to proceed.
- Rapid Sand Filtration: Filtering water removes remaining particulate matter.
- Clear Water Sump and Chlorination: Chlorine disinfects water, making it safe for consumption.
- Storage and Distribution: Treated water is pumped to storage tanks and distributed through pipelines to homes and businesses.
This comprehensive process is essential for ensuring the highest quality water for the community.
