Farming is our heritage, Filtration is our legacy.
Screen filter discs are a common type of filtration used in irrigation applications.
A disc filter is a type of water filter used primarily in irrigation, similar to a screen filter. The water passes through the small passages in between and the impurities are trapped behind.
And we are the wedge wire screen and sintered filter disc manufacturer in China.
Accurately, the filtration quality is based on the quantity and size of particles that the filtering element is able to retain. Higher quality filtration simply means cleaner water. This depends on the geometry of the channels, including the size, length, angle, and the number of generated intersection points. Filtration quality is usually measured in microns, based on the smallest size particle filtered. The typical range is from 25 microns for the finest level of filtration to 400 microns for the coarsest. Sometimes the filtration quality is given as the equivalent mesh size of a comparable screen filter. Typical mesh sizes range from 40 to 600. When using mesh sizes, 40 is the coarsest and 600 is the finest or highest level of filtration.
Disc filters range in size from small units with a 3/4" inlet and outlet used for landscape drip irrigation systems to very large banks of multiple filters manifolded together used for filtering large volumes of water for agricultural and industrial applications.
One advantage that the disc filter has over the media filter is that it can backflush more quickly with less flush water.
