IMAGINE Zeolites are used in water filtration to separate harmful heavy metal ions and organics from water. The combination of physical entrapment of fine particles and molecular sieving of contaminants produces superior water purification compared to regular sand media or anthracite.
Natural zeolites are used for particulate filtration (down to 2 micron) and for heavy metal and ammonium removal in sewage, water and swimming pool filtration systems.
Natural zeolites are used in water treatment for the removal of a wide range of micropollutants.
Zeolites are used extensively in sewage treatment plants to remove nitrogen, organic hydrocarbons, ammonia and to trap heavy metals (and toxic cations such as silver, mercury, nickel, chrome, cobalt, antimony, arsenic, etc.) from sewage effluent.
Besides working as molecular sieves, zeolites increase the biological activity of the cleaning process thereby improve the sludge sedimentation characteristics and waste water quality.
Zeolites reduce many positively charged ions, such as lead, mercury, iron, manganese,, as well as total nitrogen content, additionally adjusting the pH value. Using zeolite in waste water treatment facilities also reduces odours, chlorinated hydrocarbons and sludge index.
Waste water treatment facilities can reduce their material costs by reducing the amount of chemicals used.
Swimming pool filtration
When used as a filtration medium, zeolite helps remove even trace amounts of ammonium ions from swimming pool or spa water through the cation exchange process where the ammonium chemically bonds to the zeolite molecules. With zeolite, swimming pools require less chlorine, have reduced eye irritation, and require less chemicals & backwashing (with less lost water and energy losses) versus other filtration systems. In fact, many large commercial pools in Australia, Europe and the USA use zeolites as their preferred filtration medium.
