APPLICATION

Typically 25 to 30 pounds of replaces a 50-pound bag of sand.

THEORY OF ZEOLITE FILTER MEDIA

The advantages of using Zeolite in physical filtration systems include the following:

• The high internal and external surface area of Zeolite (@25m2/g) exceeds that of quartz by more than 10 times.
• Zeolite pore space permeability for water transmission through the grains or fragments is 100% compared to non-permeable quartz grains.
• Zeolite will tend to make slightly acidic (e.g. pH - 5.5-6.0) water more near neutral.
• The amount, or layer thickness of Zeolite in the filtration systems can be much thinner (smaller volume) than quartz sand systems because of the high “surface area and pore space” of
  Zeolite.
• Zeolite 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 Zeolite 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 Zeolite is twice that of quartz sand.

WATER PATHS FOR QUARTZ
VERSUS ZEOLITE IN WATER FILTRATION

• A 25-pound bag of Zeolite 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. Zeolite 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
• Less chlorine is needed
• Life expectancy is the same as sand
• Used Zeolite can be applied as a soil amendment for gardens and potted plants
