Zeolite can remove three major impurities from water

Zeolite has a wide range of uses, such as feed zeolite, aquaculture zeolite powder, etc. Zeolite can also remove impurities in water and is an excellent water quality improver. So what impurities in water can zeolite remove? Let's take a look!
1. Remove ammonia nitrogen from wastewater. The increase in ammonia nitrogen content in the water body will lead to the nutrient content of the water body, massive algae reproduction, a sharp decrease in dissolved oxygen, and serious deterioration of water quality, thereby destroying the water ecological balance. Therefore, effectively controlling and reducing the ammonia nitrogen content in sewage has become a new topic in modern sewage treatment technology. Our company has conducted experimental research on the removal of ammonia nitrogen by zeolite. The results of using zeolite to remove ammonia nitrogen show that the pH value of wastewater has a great influence on zeolite ammonia removal, and the maximum exchange capacity is reached at a pH value of 67.
2. Remove heavy metal ions in wastewater. Heavy metal ions such as zinc, chromium, and nickel are substances that cause environmental pollution and are extremely harmful to the human body. The elimination methods include activated carbon adsorption, solvent extraction, and ion exchange. Zeolite can remove almost all heavy metal ions in water. Experiments show that using zeolite to treat the above three heavy metal ions is better. The heavy metal ions adsorbed and exchanged by zeolite can also be concentrated and recovered. After treatment, zeolite can also be recycled and reused. . After treatment, the contents of zinc, cadmium and nickel in the wastewater were all lower than the national standards.
3. Remove radioactive materials. The ion exchange performance of zeolite can be used to eliminate radioactive 137Cs and 90Sr in water, especially the selectivity for radioactive material 137Cs, which is much higher than other alkali elements and alkaline earth elements, and the zeolite with 137Cs exchanged can remain intact. When used as a radioactive source, clinoptilolite plays a more obvious role. In order to prevent radioactive substances from spreading and contaminating, by melting zeolite, radioactive ions can be fixed in the zeolite crystal lattice for a long time. Because the dissolution of small wafers of molten zeolite proceeds extremely slowly, it takes 50 years to lose 1% of radioactive substances. At present, the Ministry of Nuclear Industry has used natural zeolite for radioactive wastewater treatment in the field of atomic energy.
