Well Pack gravel is used for deep bed in-ground wells to form a barrier between the screens and the natural deposit of the land, which in turn, allows for the well to provide very clean water. Other applications can include dewatering well and monitoring wells. All of our Well Pack products meet or exceed AWWA Read more →
The effective size of each granule of sand typically varies from 0.35mm – 1.2mm. Industrial sand filters can use graded support media layers or be installed directly over or on a distribution plate or header/lateral under-drain. Multi-Media Sand Filters are an industrial water filtration solution for removing suspended solids of finer sizes

HIGH RATE FILTRATION FS-TER-001 Page 4 of 26 Figure 1. Particle size distribution of two types of sand (Vazquez F, 2000). Material Shape: Granules can be angular (grinded) or rounded (river and sea sand); on the contrary of what can be thought, the first is less easily coupled to each other al lowing more pores than the la tter.
Sifter Screen works like a "filter" to remove large, unwanted debris out of recycled media. Using sifted media reduces the chance of clogged nozzles in your blast cabinets, siphon blaster, or pressure blaster.
surfaces. The filter types examined in the technology evaluation are centrifugal separators, automatic screen filters, plastic disc filters, and sand filters. An overview of their main characteristics is summarized in Table ES.1 and more detailed information on each system type is presented in the main body of the report.
Yardney Sand Media Filters are designed as a solution for the most challenging dirty water conditions in irrigation systems. Yardney pioneered the use of sand media filtration in 1965 and through advancing technology, continues to provide high performance and long term value in the field.
Choosing the proper metal filter media for your process isn’t always straightforward. With options ranging from mesh and screen to powder and fiber metal, there are a surprisingly large number of options to choose from. It is important to understand the characteristics of each and how both the industry and individual manufacturers classify
Yardney Industrial Sand Media Filters are designed for the most challenging dirty water conditions with a high performance solution for water filtration down to 20 microns. These durable carbon steel filters utilize a 24" sand media bed for removal of organic and inorganic suspended solids for filtering large volumes of water with very little pressure drop and a long-term value.

filter water with an average turbidity of less than 25 NTU. Dual and multi-media filters are used with direct filtration. They are able to remove more suspended material per cubic foot of filter media than sand filters. Direct filtration plants have a lower capitol cost. However, the process cannot handle large variations in raw water turbidity.
Sand Silica sand is the oldest of the filtering medias. Not all sand is created equal and if you are going to replace your old media with sand, silica sand is the way you need to go. Number 20 silica sand will filter down to 20 microns.
The ideal sand media for intermittent sand filters is a coarse sand with an effective size between 0.3 mm and 0.5 mm. The media sand grains should be relatively uniform in size having a low Uc value (less than 4.0) to promote movement of water and prevent clogging. KEYWORDS: sand/ media specifications, filter media, media grain size
Typical media based filtration systems are composed of sand, stone, organics, or other materials. The media utilized is typically chosen to target specific pollutants for removal. Media filters work in two basic ways. First, stormwater passes over and through the media.
The media filters perform the filtration of water through a thick layer of graded particles. These particles can be sand, gravel or other granular sorted materials. The filtration grade depends on the effective size of the bedding and the water velocity passing through the filter. How the Sand / Media filters work:
These stainless steel filter mesh screens are ideally suited for use in applications where you need high strength, chemical resistant filter mesh screen to filter through. They stand up well to heat, cold, chemicals, solvents, liquids, and even sand and filter media.
Kleen Industrial Services silica products meet or exceed all AWWA recommendations for filter sand and are NSF Certified. Municipalities, engineering firms, and well screen manufacturers routinely spec Kleen Industrial Services Sand and Gravel well pack media for its desirable physical and chemical properties.

Water enters one 1-1/2 port and exits on the side oposite. Water is guided through the filter which traps debris. The red valve is at the BOTTOM of the filter and is used to blow out larger pieces of debris. The clear plastic case unscrews from the white plastic pipe connection and the stainless steel filter can be washed to remove small debris.
Vertical pressure filters provide granular media treatment in an enclosed pressure vessel. Multiple vessels can be used to allow operating flexibility and backwashing from in-service cells. Under 1 MGD (4 MLD), they are more economical than horizontal pressure filters. Vertical pressure filters are typically applied in small to medium sized plants.
The abrupt reversal of motion detaches water from the material, and the water droplets pass through the screen media. The solids are conveyed up the screen by this linear motion. The uphill slope of the screen, along with a discharge weir, creates a deep bed that acts as a filter medium, allowing retention of material much finer than the screen

Place a preselected screen over the top of a second, clean bucket. Use a screen or filter with minute holes to filter out materials such as baking soda or crushed walnut shells, and use a screen with larger holes to filter debris from coarse sandblasting media.
Sand Media Filters Sand media filters are tanks typically constructed from stainless steel or coated carbon steel. The tanks are filled with a fine crushed silica sand, or “media.” Water is pumped into the tank, and downward through the media, where contaminants become caught and are …
