What Are the Functions of Zeolite Powder in Water Treatment?

The main functions of Zeolite Powder in water treatment are as follows:
1. Removal of ammonia nitrogen
Zeolite powder has a strong ion exchange capacity, especially for ammonia nitrogen (NH₄⁺), with an adsorption rate of over 98%, which is much higher than that of natural zeolite (50-90%). Therefore, it is widely used for the removal of ammonia nitrogen in municipal sewage and aquaculture wastewater.
2. Adsorption of heavy metals
Zeolite powder can effectively remove toxic metal ions such as lead (Pb²⁺), cadmium (Cd²⁺), copper (Cu²⁺), nickel (Ni²⁺), chromium (Cr³⁺), and zinc (Zn²⁺) from water. The adsorption efficiency is generally above 90%, and it is applicable in a wide temperature and pH range.
3. Removal of micro-pollutants such as fluorine and arsenic
Modified zeolite powder also has good removal effects on micro-pollutants such as fluorine, arsenic, phenols, and phosphates, and is often used in drinking water purification and groundwater remediation.
4. Improvement of water quality physical properties
Zeolite powder can remove turbidity, color, and odor from water, improving water transparency and sensory indicators, and is suitable for water treatment plants, industrial circulating water, and artificial wetland systems.
5. Synergistic filtration and regeneration utilization

Zeolite powder can be combined with filter materials such as activated carbon and anthracite to form a multi-level filtration system, improving the overall treatment efficiency, and its own can be regenerated multiple times for use, reducing operating costs.
In summary, due to its high adsorption capacity, ion exchange ability, and environmental friendliness, zeolite powder has become an efficient, economical, and sustainable purification material in the field of water treatment.
