Gravity filtration equipment uses the hydrostatic pressure of a pre-filter column above the filter surface to generate the flow of the filtrate. Common products include bag filters, gravity nutsches, and sand filters. Bag filter - Bag filters are used mainly as collection equipment. They use bag-shaped woven-fabric or felt filters.

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 granule of sand typically varies from 0.35mm – 1.2mm.

The efficiency of a sand filter relies on both its design and the application in which it is being used for. In wastewater and/or surface water filtration applications, the quality of the water can vary depending on the performance of the treatment system that is currently in place prior to the filter. As it pertains to surface water it is ...

Slow sand filters usually have loadings of 1 gpm/ft 2 (0.68 lps/m 2) or less. As a consequence they require more floor space. Unlike the rapid sand filters, these are usually provided on a custom design and manufacturing basis (see Example 10.2). They are usually unpressurized, although a positive displacement pump applying a partial vacuum to ...

Slow sand filtration works primarily through biological activity that takes place on the surface of a sand bed (Baruth, 2005).During the design and operation of slow sand filters, extra care needs to be taken in order to maintain an active biological population within the sand.

Either of two backwash techniques can be used, depending on the design of the media support structure and the accessory equipment available: High-rate backwash, which expands the media by at least 10%. Backwash rates of 12-15 gpm/ft² or higher are common for sand, and rates for anthracite may range from 8 to 12 gpm/ft².

The Rapid Sand Filter (RSF) water treatment equipment differs from the Slow Sand Filter water treatment equipment in a variety of ways, the most important of which are the much greater filtration rate and the ability to clean automatically using back washing. The mechanism of particle removal also differs. Rapid sand Water filter does not use biological …

Unlike traditional sand filters, multi-media water filters are composed of three filtration media, ordered in decreasing porosity. Because of their multi-layer design, multi-media water filters are able to trap and retain a far larger number of particles than traditional sand filters before backwashing becomes necessary.

Slow Sand filtration was the first type of porous media filtration used in water treatment. This process is known for its simplicity and efficiency. During the initial operational period of slow sand filters, the separation of organic matter and other solids generates a layer of biological matter on the surface of the filter media.
