The effect of alumina balls in water treatment is relatively good. Everyone knows this, but many people do not know when to replace the alumina balls. Some people even replace the alumina balls before they can work. This not only wastes financial resources, but also wastes resources, so when should the alumina balls be replaced?
Good time for alumina ball replacement:
1. See if the activated alumina ball is discolored and yellow.
2. See if the service life exceeds two years, if it exceeds two years, it should be replaced immediately.
3. Check whether the humidity of the processing gas is too high. If the humidity is too high, note the foot, which means that the activated alumina ball may be invalid.

4. It is obvious to see whether the content of fluorine in the fluorine-containing water exists. If it is obvious, it means that the activated alumina ball needs to be replaced.
Activated alumina balls are white spherical porous particles with average particle size, smooth surface, high mechanical strength and strong hygroscopicity. Under certain operating conditions and regeneration conditions, the drying depth of activated alumina is as high as -70 degrees below the dew point temperature.
Activated alumina balls can be used as defluorination agent for high fluoride drinking water (large defluorination capacity), defluorination agent for circulating alkane in the production of alkylbenzene, deacidification and regeneration agent for transformer oil, used in oxygen production industry, textile industry, Gas drying in the electronic industry, drying of automatic instrument air, and desiccant and purifying agent in chemical fertilizer, petrochemical drying and other industries, and dew point of pressure swing adsorption in the air separation industry can reach -55 degrees. It is a kind of deep drying of trace water agent.
