Needed ( and chart of various tank sizes ).High purity, low sodium, natural, zeolite, mineral ( 14 x 40 mesh ) that is classified as ANSI/NSF Standard 61.
Used instead of sand/anthracite, pecan shells, or other coarse filtration material to efficiently remove suspended solids and fine turbidity particles.
The filter granules physically filter and trap the suspended solids.
In addition, the granules remove a wide range of colloidal and soluble, inorganic metallic, contaminants by surface sorption, chemical-binding, charge-neutralization, coagulation, reactions and /or ionic, ion-exchange phenomena.
Provides higher service flows and longer filter runs than equivalent sand filters.
Excellent filter media for filtering out sediment, rust and particles down to 5 microns.
The material is mined, crushed, dried and double-screen, sized to produce a high quality filter media with Uniformity Coefficient (D60/D10) of 1.7 having high through-put capacity at low differential pressure. The alumino-silicate, crystal, mineral material has surface micro-mineral projections with 0.25 to 10 m spacing that effectively trap suspended solids in water streams. The surface, micro-projections, together with the high surface area makes this material an ideal, water filtration media.
