Multimedia (sand) Filtration Calculation
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.

SAND FILTER SYSTEM GUIDE
sand filter. Sand filters produce high quality effluent, significantly reducing fecal coliform bacteria, removing organics, and nitrifying ammonia. Septic tank effluent is pumped to the top of the sand filter bed into distribution laterals, which releases the effluent through orifices in the pipe.

Rapid Sand Filter Design. Problem: Design a rapid sand filter to treat 10 million litres of raw water per day allowing 0.5% of filtered water for backwashing. Half hour per day is used for bakwashing. Assume necessary data. Solution: Total filtered water = 10.05 x 24 x 10 6 = 0.42766 Ml / h 24 x 23.5. Let the rate of filtration be 5000 l / h

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

Filtration
Filter Sand . The filter sand used in rapid sand filters is manufactured specifically for the purpose of water filtration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration.

Slow Sand Filtration: Design, Operation, and Maintenance
The slow sand filter Basically, a slow sand filter consists of a tank constructed of reinforced concrete, ferrocement, stone or brickwork ma-sonry, plastics, or even metal, which contains a supernatant layer of raw water, a bed of fine sand, a system of underdrains, an inlet and outlet struc-ture, and a set of filter regulation and control devices.

Worksheet For the Installation of a Sewage System
The extended area is built with the very fast draining filter sand. There is the ability to design the system so that the “seam” where the fast draining filter sand meets mantle sand would end up buried under a sideslope. This is desireable as this is the most at risk area for this type of system to fail or pond water to the surface.

Water Handbook
The most desirable media size depends on the suspended solids characteristics as well as the effluent quality requirements and the specific filter design. In general, rapid sand filters use sand with an effective size of 0.35-0.60 mm (0.014-0.024 in.) and a maximum uniformity coefficient of 1.7.
