Natural zeolites are aluminosilicate minerals, the appearance of white or brick red, is a weak acid cation exchanger, through the artificial introduction of the active ingredient, it has a new ion exchange or adsorption capacity, adsorption capacity will also increase accordingly. Mainly for small and medium sized boiler water softening treatment to remove water calcium and magnesium ions, thereby reducing boiler scale formation, reduce water measured corrosion of metals, extend the life of the boiler. In wastewater treatment, it can be used to remove phosphorus and lead and hexavalent chromium. Zeolite can be used after failure after repeated use countercurrent regeneration brine.
