We use the Pentair/ Fleck 2510 and 7000 Control Valves. These are excellent control valves for filtration. They both have programmable features that set them apart from other units.
High purity, low sodium, natural, zeolite, mineral (14” x 40”
mesh) that is classified as GRAS (Generally Recognized As
Safe) under 21CFR Part 182.2729 and 40 CFR Part 180.1001
with ANSI/NSF Standard 61 Listing. 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 mm
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. The material is mineralogically and
thermally stabile to 500° C. Advantages of ChemSorb®
Filter Granules versus conventional sand, anthracite and
multimedia filter media are below.
Higher filtration capacity without additional capital costs.
Reduced backwash frequency reduces costs and saves
High flow rate capacity - gravity fl ow (4 gpm/ft2 ) and
pressure vessels (12-18 gpm/ft2 ).
Linear/near linear, head loss curve with superior, depth
removal of suspended solids.
Superior filtration rating (5 micron nominal) translates to enhanced water quality.
Bulk Density: ........55 lbs. per cubic foot
Mesh Size: ...........14 x 40
Surface Area: ........Avg. 24.9 m2/g
Surface Absorption: ..Hydrophilic
Thermal Stability: ...Stable to 500° C
Used as a water/liquid, filter bed (or tank) material in lieu
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, chargeneutralization,
coagulation, reactions and/or ionic, ionexchange
