PURE            VERSATILE               NATURAL                ZEOLITE A WHOLLY OWNED SUBSIDIARY OF UNITED STATES ANTIMONY CORPORATION 406-827-3523 or tfl3543@blackfoot.net   BRZ™ FOR WASTEWATER TREATMENT

  ChemSorb® Sorbent Powder is an advanced, surface water turbidity and silt sorption and

  flocculation product developed for municipal drinking water plants and industrial pumping stations. stations.
  Auger or slurry fed, product doses of 2-3lb/1000 gal of surface water is used (higher turbidity

  water requires higher doses). The sorbed/flocculated solids are granular (1.2-1.4 Sp. Gravity,

  w/water = 1.00); readily settle; and easily dewaters.

• Drinking water-Alum & polymer flocculation chemistry replacement.

• Turbidity, silt, algae (bio-particle) & TOCs removal from surface water.

• Enhances clarification performance; decreases filter bed solids loading.

•  Mineral:          Natural zeolite primarily clinoptilolite (see specification sheet)

• Size:               -40 mesh (fine powder)

•  Color:             Pale green color (dark green when wet)

• Hydrophilic:

• Weight:           55 pounds per cubic foot

• GRAS:             Classified “GRAS” (generally regarded as safe)
               under 21 CFR Part 182.2729 and 40 CFR Part 180.1001

• NSF:                NSF/ANSI standard 60 listed for drinking water treatment

• Surface Area:            Surface area 24.9m²/gram

• Availability:    Sold as “ChemSorb® Sorbent Powder” by Filter Flow Technology, Inc.
              and Bear River Zeolite www.filterflowtech.com

• BETTER SOLID/LIQUID SEPARATION THAN ALUM AND POLYMER. The specific
  gravity of the alum/polymer floccules is 1.03 and this results in many “pin flocs” that do
  not settle. The specific gravity of the BRZ/iron compound system is 1.4 and this results
  in a clean solid/liquid separation and interface giving better clarity.

• BRZ SYSTEM REAGENT NOT BULKY. The alum/polymer reagent is bulky and hard to
  handle compared to the BRZ system.

• SPENT BRZ REAGENT CAN BE LAND APPLIED. The spent alum/polymer reagent
  must be taken to a licensed land fill.

• LOWER COST WITH BRZ. Although the reagent cost of the BRZ systems is about
  10% higher than the alum/polymer system the overall cost is much less due to easier
  dewatering and the lower solids management cost.

• BETTER REMOVAL OF HEAVY METALS, CERTAIN HYDROCARBONS,
  CHLORAMINES, AND AMMONIUM.
