Using BRZ™ natural zeolite in physical filtration systems provides the following advantages:

• The high internal and external surface area of BRZ™ (@25m²/g) exceeds that of quartz by
  more than 10 times.

• BRZ™ pore space permeability for water transmission through the grains or fragments is
  100% compared to non-permeable quartz grains.

• BRZ™ will tend to make slightly acidic (e.g. pH - 5.5-6.0) water more near neutral.

• The amount, or layer thickness of BRZ in the filtration systems can be much thinner
  (smaller volume) than quartz sand systems - because of the high “surface area and pore space” of BRZ™.

• BRZ™ fragments tend to be discoid shaped, rather than round, thus presenting a large
  surface area (per unit of mass) (see diagram below).

• The density of 2-4 mm granules of BRZ™ is about 55-60 lb/ft³, which is about half of that of quartz grains of similar size. Thus the volume of one ton of BRZ™ is twice that of quartz sand.

WATER PATHS FOR QUARTZ VERSUS ZEOLITE IN FILTRATION

• Mineral:          Consists of a volcanic mineral called "clinoptilolite" (see spec sheet)

• Size:               14 x 40 mesh

• Color:             Pale green when dry, dark green when wet

• Particle size: Average 0.7 mm

• Uniformity index: 1.9

• NSF:                ANSI/NSF Standard 50

• Weight:           Density 55 pounds per cubic foot (880kgs/cubic meter)

• Surface Area: 24.9 square meters per gram

• GRAS:             Classified as “GRAS” (generally regarded as safe)
               under CFR Part 182.279, 40 CFR Part 180.1001

• Hardness:      Low clay, hard, abrasion resistant

• Availability:    Sold as “Zeo Sand ® Natural Zeolite Filter Media” by Zeo Inc.

•  Typically 25 to 30 pounds of BRZ™ replaces a 50 pound bag of sand.

• A 25 pound bag of BRZ™ has the surface area of over 50 NFL football fields, while a 50 pound
  bag of sand only covers 1 football field.

• Increased flow rate

• DE like clarity. Nominal 3 to 5 micron rating

• Reduces backwash time by up to 50%

• Higher loading capacity than sand

• Less eye burning. BRZ™ exchanges ammonium from urine directly into the crystal lattice
  where it is not water soluble. As a result, less chlorine is use and fewer chloramines
  are formed (that burn the eyes).

• Less chlorine is needed

• Life expectancy is the same as sand

• Used BRZ™ can be applied as a soil amendment for gardens and potted plants
