The Disc Filter is a high-rate filtration device that utilizes an innovative woven polyester pleated filter panel design. The Disc Filter inside out filtration design allows the water to flow into the center drum and then out through the disc filters capturing solids on the inside surface of the media. This filtration characteristic eliminates the need for a separate system for handling floating material and settling sludge. The captured solids are also backwashed into a reject trough using a one-pass spray cleaning system. A backwash cycle is automatically initiated by a level probe in the influent channel with filtration continuing during backwash.

For achieving turbidity levels less than <5 NTU this solution is used.
