activated alumina for remove fluoride
It is widely used in petrochemical, oil refining, electronics, ethylene, propylene, air and other drying devices.
In the country a lot of hydrogen peroxide plant, chemical fertilizer plant, oxygen plant and petrochemical refining
units use it , and have achieved good results. Activated alumina ball is also based on the strength of
adsorption of substances to determine the polarity of water, and has strong affinity of oxides, acetic acid,
alkali and so on . It is a water depth micro-desiccant, also be the absorbent adsorption of polar molecule . It can be widely used in petroleum
cracking gas, deep drying of ethylene propylene and the dry hydrogen-making, air separation plant, instrumental air-dry machine , fluoride treatment in hydrogen peroxide . But also can remove sulfur gas hydrogen, carbon
dioxide, hydrogen fluoride, hydrocarbons class and other pollutants in waste gas, especially for adapting to
fluoride treatment in the water containing fluoride.
