Description
The Rapid Sand Filter is a widely used water purification system designed for the quick and effective removal of suspended solids, turbidity, and impurities from raw water after coagulation and sedimentation. It operates at a much higher filtration rate than slow sand filters, making it an essential model for demonstrating modern municipal water treatment processes.
Ideal for public health laboratories, environmental engineering departments, medical colleges, and water supply training institutes.
