Product Description

USAGE: Media filters X Series through their three dimensional structure can remove large amounts of mainly organic materials. Vertical/single tank media filters can be installed as singles or in expanded batteries and can be back-washed manually or automatically, (by adding the appropriate backwasing KIT). Dual chamber media filters are mainly recommended for small installations and can be also back-washed manually or automatically. Back-up filters (screen or disc) should be installed downstream to media filters to prevent irrigation system from clogging, if any failure occurs. EQUIPPED WITH: Air release valve and drain plug # Silica sand and backwashing KIT upon request SAND: River, beach, and creek sand tend to have rounded, soft edges and are not suitable for media filters. Crushed silica sand is used frequently and it offers excellent results. All particles in a bag of media are not the same size. The "uniformity coefficient" (UC) is an index, which describes the variability in particle sizes in a sample. A value of 1, 0 indicates that all particles are of the same size. Most acceptable sizes 1, 4 - 1, 6. During the back flushing process, the finer particles tend to migrate toward the top of the bed where eventually shape the "mean effective media size". By specifying the material type, the UC, and "mean effective media" size, one can obtain the desired filtration. Usually the majority of the debris is captured within the top *0cm of the media bed, so it is obvious that must be flushed frequently. As during the back flushing procedure one part of the sand could be flushed out with the water, it is necessary to periodically add some more to the filters. At the end of the irrigation period sand should be inspected so to confirm the quality and quantity level. When the amount of dirt that cannot be back flushed prevents the proper functioning of the filter sand should be replaced (recommended every **3 years - however it depends on local conditions)
