SAND FILTER ZELBRITE 15kg BAG

The active ingredient of the zeolite is and clinoptilolite and, a mineral with very special properties. These include an exceptionally high surface area, an infinitely extending three-dimensional cage-like structure with large internal pore spaces, and the ability to chemically capture pollutants by a mechanism called and cation-exchange.

These properties enable three mechanisms to interact to produce superior filtration.

First there is physical capture between particles as occurs in conventional sand filtration. Secondly there is capture of pollutants onto the very extensive surface area of Zelbrite by adsorption. Chemical pollutants such as ammonia are captured by the third mechanism of cation exchange.
