Product Description

Multi-Media Sand and Gravel Filters



Multimedia Sand Filters
Following multi-layer filtration, Multimedia Sand Filters are most recommended systems to remove suspended particles, color, odor and iron from ground water and wastewater. Multimedia filtration works on pressurized filtration process, where three layers of filter media are used for fine particle removal approximately 5 to 25 microns. As compared to conventional sand filters, multimedia filters offer superior filtration quality, longer filtration cycles and lower water consumption during backwash; hence, these filters offer a flexible and feature-rich way to reduce the amount of suspended solids and turbidity in feed water. These multimedia filters are mostly used as pretreatment to reverse osmosis, DM and softener.

 Working Principle
 
Also refers to multi-layer filter, a typical multimedia filter contains three layers of filter media (anthracite coal, sand and garnet). The principle behind using these three types of filtration media is the difference between particle size and density properties of these materials. Anthracite media is the lightest and largest particle size media, which remains of top following backwash while the intermediate size media (sand) will settle in the middle and garnet, the heaviest but having the smallest particle diameter, will settle to the bottom. Periodically backwashed is mandatory to remove contaminants trapped in the media during filtration process.
 
This kind of arrangement allows the largest dirt particles to be removed at the top media bed and the smaller and smaller dirt particles being retained deeper and deeper in the media. This down-flow filtration permits delivery of high quality filtered water at much faster flow rates; typically particle removal approximately 5 to 25 microns.
