either vertical or horizontal pressure filters, as well as gravity filters. GreensandPlus is a proven technology for iron, manganese, hydrogen sulfide, arsenic and radium removal. Unlike other media, there is no need for extensive preconditioning of filter media or lengthy startup periods during which required water quality may not be met.
In slow sand filtration, the vertical height of the sand bed that the water has to pass through is important in terms of filtration efficiency. The reasons for this are the existence of biological activity in a sand filter, which is known to occur at depths of up to 0.5m within a sand bed, and the available surface area for mechanical ...

These filters consist of a coating of anthracite (1.25-2.5mm) resting on a coating of fine sand (0.6-1.5mm) Anthracite is coarse and has more dirt holding capacity as compared to fine sand. During the filtration cycle the largest particles are strained out by the anthracite then the sand traps the rest of the particulate matter though a ...
Vertical pressure filters provide granular media filtration in an enclosed pressure vessel. Multiple vessels can be used to allow operating flexibility and backwashing from in-service filters. Under 0.75 MGD (2.8 MLD), they are typically more economical than horizontal pressure filters. They are usually found in small to medium sized plants.
Sand Filters Filtration solutions that help maintain water quality in your aquatic facility and life support system Filtration is a key element of water treatment for swimming pools, water slides, splash pads, fountains, life support systems and other bodies of water found in aquatic facilities.
The media are loaded by density—the most dense in the bottom of the tank, the least dense on top. This produces a filter with excellent flow rate and and relatively easy backwash properties that will filter down to ten microns. The most common media mix is (top to bottom): anthracite, filter sand, garnet 30 X 40, garnet 8 X 12, and gravel.
However they also provide excilent filtration for wells plagued with sand. Flow Guard filters clean themselves by directing water into the top othe filter and through a bed of sand where the undesirable particulate are capuured. ...

The most common multimedia filter consists of sand and anthracite as the filtration media. The sand has smaller grains and is heavier than the anthracite. This ensures that the sand layer settles beneath the anthracite and provides finer filtration. A well operated Multimedia Filter can remove particulates down to 20 microns.
H2K industrial sand filters are designed to remove larger suspended solids (50-100 microns), using a single size of filtration media. The coarseness of the filtration process can be determined by adjusting the size of the filter sand. The effective size of each …
Series 1100 Stainless Steel Media Filters Flow-Guard Media Filters provide superior filtration in any irrigation application. Utilizing three-dimensional filtration through media bed with a large surface area has proven to be the most effective and reliable way to remove both organic and inorganic contaminant loads from irrigation source water.
