The grooved disc element provides better filtration than many of the screen and other type filters on the market. The disc filters can be used whenever organic materials, sand or sediments are present in the water source. The filter disc element provides in-depth filtration as the sediments or organic materials accumulate on the outer face of the stacked discs. The disc element is readily accessible for easy removal and cleaning. Unlike the screen, the disk filter element consists of stacked round grooved discs, which utilize three-dimensional filtration to stop organic materials, sand or other sediments. In cross section, the numerous small grooves on each side of the stacked discs act to disrupt and then block flow of organic material as the water moves through the filter. A number of the stacked grooved discs assembled together makes up the filter disc element assembly. Each size of grooved disc assembly has a distinct color representing a variation in degree of filtration.When water flows through the disc element, organic materials and sediment accumulate along the outside diameter of the disc element. As this occurs, there is a drop in pressure between the incoming water and the downstream water exiting the filter, forcing organic matter into the depths of the grooved disc element until stopped. If used with low water quality and not cleaned in time, the filter will come to have a fixed pressure on the inlet side of the filter and a zero pressure on the outlet side, assuring that regardless of the type of water used, water flow will be essentially stopped, and dirty water will not enter the drip system.
