Water Treatment

Researchers and engineers are turning to natural Zeolite as a valuable tool in water treatment processes in the quest for clean and safe water. This remarkable mineral, known for its unique properties, revolutionizes water treatment by offering a range of benefits that contribute to efficient and effective water purification.

Removing Contaminants from Drinking Water

Natural zeolites excel at removing harmful contaminants from drinking water. With their cation-exchange selectivities, they can selectively remove radioactive cations like Cs+ and Sr2+ and heavy-metal cations like Cu2+, Cd2+, Zn2+, Ni2+, and Pb2+. By harnessing their ion exchange capabilities, natural zeolites ensure the targeted removal of specific pollutants, resulting in cleaner and safer drinking water.

Enhancing Ion-Exchange and Filtration Bed Efficiency

Natural zeolites enhance filtration due to their large surface area—at least 10 times greater than sand—allowing efficient adsorption of suspended solids, microorganisms, and dissolved impurities. By incorporating zeolite rock, filtration systems achieve improved impurity removal, leading to clearer, higher-quality water. Zeolites also support nitrifying bacteria that convert ammonium (NH4+) to nitrate (NO3-), combining ion exchange, filtration, and microbiological processes to remove contaminants effectively. Thus, zeolites aid in both filtration and purification by capturing impurities and converting NH4+ to NO3-.

Industrial Wastewater and Sewage Treatment:

Natural Zeolite is a valuable tool in treating industrial wastewater and sewage. It is a coagulating agent, working with other compounds to remove suspended solids, including microorganisms, from wastewater. This application is particularly noteworthy for its effectiveness in eliminating harmful microorganisms, ensuring a higher level of disinfection. Furthermore, natural Zeolite is known for its exceptional ion-exchange selectivity and adsorption properties, which play a crucial role in removing heavy-metal cations, NH4+, and low-concentration organic and inorganic molecules from industrial wastewater and sewage, contributing to the overall treatment process. Their mechanical strength suits various technical applications, including filling fixed bed ion exchangers or adsorbents. Natural zeolites remain stable within a broad pH range, insoluble in organic solvents, and undergo multiple dehydration-rehydration cycles without significant hysteresis. Furthermore, natural Zeolite (chabazite) exhibits impressive thermal stability in various gases. These properties make natural Zeolites highly valuable for effective and efficient industrial wastewater treatment.
