Water is not found in its purest from nature. It is always contaminated with physical, chemical and biological impurities. Proper filtration is of much importance to prevent low pressure diffuser like emitters from clogging. Inline filtration is a technology that has been used for portable water filtration. The inline filter is composed of a metallic body, gear crown, main drain, opening valve (backwashing), a pump for injecting clean water to the nozzles and a geared motor for rotation crown and measure and control elements running. The filtering element is a special screen, fixed to the rotation crown, for filtering all kinds of dirt particles, with a hydrodynamic profile that provides low head loss and reduces turbulences, reduces head losses and avoid dirt particles accumulation. All the materials are top-quality, in all the mechanic elements that are in contact with water it is used stainless steel or similar. The filter body is made of carbon steel. The mechanic elements are in the “clean water” side (water under the screen) in such a way that no foreign object can affect its performing or deterioration. Inline filters fit directly to the pipe by means of flanges, as it was one more element of the pipe. Only the electric and control elements require installation. It is a self-backwashing automatic filter that has minimum maintenance and low consumption. Water goes through the rotative screen and all the dirt particles bigger than the screen holes get filtered. When the default pressure differential, backwashing starts, this is made area by area, collecting waste materials to be expelled to the exterior. The backwashing cycle starts when the default differential pressure is detected on both sides of the screen. At that moment, filtration process is completed.
