Sand & Multimedia Filters
Sand filters are used to remove suspended solids from water and wastewater. Because they have one layer of filter media, sand filters remove only relatively large solids (normally in the range of 40 micron and larger). The effective size of each granule of sand typically varies from 0.35mm – 1.2mm. Larger granules yield coarser filtration. Finer granules yield finer filtration.
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.
Dual and Multi-media filters are typically used for:
- Industrial process water
- Waste water
- Potable (drinking) water
All of our sand & multimedia filter 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.
