Turbidity is the measure of solids (or “suspended particulates”) present in water, such as sediment, suspended iron and organic particulates. Turbidity affects the transparency of the water, often giving it a murky brown or grey colour.

Turbidity in water should be no greater than 4.0 NTU’s (Nephelometric Turbidity Units) or FTU’s (Formazin Turbidity Units).

Filter-Ag Plus is made from an all natural ore called clinoptilolite, which is made up of angular granules with a rough surface and microporous void spaces as small as 3 microns. These features allow Filter-Ag Plus to reduce sediment and organic matter suspended in water by bridging, straining and adhesion.

Compared to normal sand filters, Filter-Ag Plus’ rough surface and internal porosity allow for much longer and more effective filter runs and a high capacity for sediment loading. This reduces backwash frequency and conserves water.
