Combined with the previous discussion on the application of zeolite powder in water treatment, the performance comparison between white zeolite powder and green zeolite powder in ammonia nitrogen removal is as follows:
Core Ammonia Removal Performance Difference
White zeolite powder has a higher purity of clinoptilolite, with fewer impurity components such as iron oxide and heavy metals. Its internal pore structure is more regular, and the cation exchange capacity is significantly higher than that of green zeolite powder. Under the same water quality conditions, its ammonia nitrogen removal rate can reach 92%~97%, while the ammonia removal efficiency of green zeolite powder is usually maintained at 75%~85%.
Applicable Scenario Difference
White zeolite powder is more suitable for high-standard water treatment scenarios such as drinking water purification and municipal sewage advanced treatment that require strict control of ammonia nitrogen index. Green zeolite powder has a lower raw material cost, and it is more cost-effective in scenarios such as industrial primary wastewater treatment and landscape water purification that do not require extremely high effluent standards.
Stability in Long-Term Operation
White zeolite powder has more stable structural performance. After multiple regeneration cycles, its ammonia nitrogen adsorption capacity only decreases by about 5%~8%, while green zeolite powder has more impurities, and its performance attenuation will exceed 15% after the same number of cycles.
