Selection of optimum filtration rates for sand filters

The early rapid sand filter systems were proprietary devices, the first one patented by I. W. Hyatt in 1884. A number of others were on the market in the mid 1890's when 0. W. Fuller was retained by the Louisville Water Company to test the suitability of rapid sand filters for the treatment of Ohio River water at Louisville, Kentucky.

Pressure Sand Filter Calculator | WE - Water Engineer

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 ...

HVAC air filters Calculating the cost

highlights the differences in cost between different filter classes. When the calculation is made for a filter class M5 we get the results seen in Table 2. As we can see from the calculation, the total cost (optimised concept) for a filter of class M5 is 1020 US$. Upgrading from M6 to M5 will lead to an increase in costs of 730 US$ (1750-1020 US$).
