The water filtration industry has used clinoptilolite zeolite for years for swimming pool filtration and municipal water treatment. Clinoptilolite zeolite has also been used to control odors and remove toxins from the air. The mining industry uses clinoptilolite to control ammonia in blasting and to clean effluents. Environmental remediation efforts have recognized that the high cation-exchange capacity of clinoptilolite zeolite is effective for the removal of ammonium, heavy metals, light metals, sodium and radioactive isotopes from groundwater.
