A ''' | A '''Disc Filter''' is a type of water filter used primarily in irrigation, similar to a [[Screen Filters|screen filter]], except that the filter cartridge is made of a number of disks stacked on top of each other like a pile of poker chips. The water passes through the small grooves in between and the impurities are trapped behind. Some types of disk filters can be backflushed in such a way that the disks are able to separate and spin during the cleaning cycle. | ||

*As the name implies, the filter consists of a stack of discs. These discs are like hollow poker chips with serrations that cause the discs to interlock when the discs are stacked. | *As the name implies, the filter consists of a stack of discs.

*Water enters the filter chamber on the outside of the discs. The water then flows through the disc pack between the interlocked serrations of the discs. After flowing through the serrations the water then flows through the hollow center of the discs and out to the field. | *Water enters the filter chamber on the outside of the discs.

*Back wash is accomplished by reversing water flow. When flow is reversed, water enters into the hollow area of the disc stack causing the stack of discs to lengthen. As the stack lengthens the discs are separated from one another. Water then freely flows outward pushing all dirt caught between the discs to a dump line. Additionally, water is sprayed through nozzles inside the disc stack aimed outwards causing the discs to spin and rub against each other further cleaning the discs. | *Back wash is accomplished by reversing water flow.
