2020-12-14 Pressure Sand Filter Calculation. Pressure sand filter is widely used filtration system for the removal of suspended solids and turbidity in the feed water. This tool is useful in determining the diameter of the filter vessel. Flow (LPH) Filtration Velocity (m/s) 10 (Natural river water) 15 (UF/UV/RO pre treatment) 20 (STP/ETP tertiary

These filters are called multi-media filters because they contain different layers of filtration media ordered in decreasing porosity. Multi-media water filters are able to trap and retain a far larger number of particles (generally down to 10-25 microns) than traditional sand filters before backwashing becomes necessary.

#### Pressure Sand Filter Calculator WE Water Engineer

2020-7-30 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

Design filtration rate is v = 10 m/h. The filter requires flushing each seven (7) hours, with flushing time is t = 0,2 h. q = 10 m³ of water is used for one flushing. Operation is carried out 24 hours a day, i.e. the total working time is t об = 24 h. It is required to calculate the required number of filters. Solution:
