Product Description

A rapid sand filter is a water treatment device that uses sand or other grainy media to filterout the solid particles suspended in water. These suspended solids include dirt and other organic matter that cause water to appear cloudy or turbid. Rapid sand filtration is commonly used by municipal water treatment plants to clean surface and ground water intended for drinking water. It is also used to treat sewage and industrial wastewater containing biological contaminants before these waters are discharged to the environment.
Rapid sand filtration takes place in a tank containing one or more layers of grainy media, such as sand, anthracite or hard coal, garnet, magnetite, or other minerals. The total media depth typically ranges from 2-6 feet (about 0.6-1.8 meters). In many systems the incoming water, or influent, enters near the top of the tank and flows downward through the media. The outgoing water, or effluent, leaves through a drainage system called the underdrain that lies underneath the filter media bed.

Sand filters are typically used for:  

Irrigation water
Storm water
Cooling water
Swimming pool water
Water in fountains and other water features
 
Removing suspended solids smaller than 40 microns requires filters with either two or three layers of filter media. These are referred to as dual-media filters or multi-media filters. When sized properly and with the correct configuration of filter media, these filters can remove suspended solids as small as 5 micron.
Units are skid-mounted, factory assembled, wired, and tested, and delivered ready for installation. Piping, valves, filter media, pressure gauges and accessories are included with filter systems. Solar power, media air scour, and rinse cycle are available as options. Filter systems are engineered to require little maintenance. A separate source of water supply or a pump for backwash are seldom needed.
 
Dual and Multi-media filters are typically used for:
Industrial process water
Waste water
Potable (drinking) water.
The size of each filter, the number of filters required, and the type of filter media used depend upon:
how small a solid needs to be removed,
how dirty the water is,
how the water will be used once it is filtered,
and the source of backwash water needed to clean the filters
