Pressure Sand Filter Calculator

Calculation for pressure filter design.

Pressure sand filter is the first unit process in any treatment. It is used to remove suspended solids from raw water.

Filter is designed based on velocity consideration. Recommended velocity for filtration is 10 m/hr to 30 m/hr.

If we select velocity less than 10 m/hr, channeling will happen and velocity higher than 30 m/hr will lead to high differential pressure.
