Multiple Choice

Which filter is designed to remove fine particles using stacked discs and is often self-cleaning?

Disc filtration uses a stack of small, precise discs that create very fine openings, providing a high filtration efficiency in a compact package. As water passes through the packed discs, fine particles are trapped in the narrow gaps between them. A standout feature is the automatic self-cleaning capability, where the filter periodically backwashes or wipes away the accumulated sediment, keeping the flow clear without manual cleaning. This combination—fine particulate removal plus self-cleaning—makes it the best fit for removing small particles from irrigation water. Other options rely on screens, a media bed, or disinfection, rather than stacked discs, and don’t match the described design and function.
