As dirty water or solution is pumped into the filter and pressure increases on the outside of the filter element, the water or solution pressure compresses the rings tightly together increasing efficiency. Grooves in the disc rings criss-cross, forming a network that traps both organic and inorganic contaminants from the water source. This design filters the dirty water or solution thoroughly - not only on the outer surface of the cylindrical disc filter element - but through the entire depth of every ring groove. Clean water or solution exits from the inside of the cylinder.
