Industrial 3-5mm desiccant Activated Alumina Ball for air compressor water vapor adsorption ball: Activated Alumina with high strength, low abrasion, no soften in water, no expansion, no powdery and no crack. It can widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen-generation, air separation, instrument air drying and fluorine treatment for H2O2, also in the absorbing pollution material, such as H2S, SO2, HF and paraffin in the waste gas, especially in the drinking water defluorinate. Activated alumina Advantages: 1. High Strength, non-toxic, odorless,water insoluble 2. No bing soft, swelling or fracturing in water 3. Easy renew, long service life 4. Large specific surface, pronounced effect on the defluorination and arsenic-removing, as well as decoloration and deodorization of sewage.
