Silica Source of Silica Silica (SiO 2) is an oxide of silicon, and is present in almost all minerals: It is found in surface and well water in the range of 1 - 100 mg/i.Silica is considered to be colloidal in nature because of the way it reacts with adsorbents. A colloid is a gelatinous substance made up of non-diffusible particles that remain suspended in a fluid medium.

Chemical Treatment and Filtration. Filter Design: Greensand filters are typically designed to flow at 3-5 gpm per square foot of filter surface area and need a minimum of 12 gpm per square foot for backwash. Backwash should be initiated manually or by pressure differential switch when the differential pressure across the filter increases by 12 psi.
