Reliable Suspended Solids (TSS) and Turbidity Removal

Water Tech high quality anthracite, sand, garnet, and gravel filter multi-media, and engineered filter systems provide reliable removal of suspended solids and turbidity in water treatment applications.

Multimedia water filters utilize anthracite, sand, gravel, and garnet with a gravel under bed, chosen for their distinct density and size differences. Anthracite - the lightest, most course media at the top, sand in the middle, and garnet - the heaviest, finest media at the bottom.

This filtration layering allows the largest contaminants to be trapped in the top filter layer, with smaller particulates sifting farther down into the lower layers, providing more efficient turbidity removal and longer run times between backwash cycles. A sand-only filter filters particles to about 20-25 microns in size, and a multi-media filter to about 10-20 microns.

Water Tech coagulants can also be applied upstream of a filter to improve removal of very fine particles through “direct filtration” or "agglomeration".

Water Tech also supplies pre-engineered multi-media filter tanks and systems in all sizes.
