Rotek - Multi Sand Filter Media Brochure

Rotek Gravel is a natural ore that has many outstanding advantages over more common granular filter sands and multimedia used for suspended solids reduction. The angularity of the granules and the tapered internal pore spaces allow for reduction of dirt, silt and organic matter suspended in water by bridging, straining and adhesion. The rough surface and internal porosity provide a high surface area for efficient removal of suspended matter. Using deep bed filtration can typically reduce suspended solids down to the 5 micron or less range. R TEK Gravel granular structure typically creates less pressure loss through the filter and allows deeper sediment penetration into the bed for higher suspended solids loading and longer filter runs.
