Natural zeolite is made of aluminum silicate minerals, the appearance of white or brick red, is a weak acid cation exchange agent, the man into active components, it has a new ion exchange or adsorption, adsorption capacity also increases. Mainly for small and medium sized boiler water softening treatment to remove water calcium and magnesium ions, thereby reducing the formation of boiler scale, reduce the water measuring the corrosion of metals, extend the life of the boiler. In wastewater treatment, water can be used to remove phosphorus and lead and hexavalent chromium. The zeolite can be used after failure of brine upflow regeneration after repeated use.
