Any product in the world has a life cycle. When the product is used for a certain period, it must be replaced in time. Activated alumina is an adsorbent with strong adsorption performance. When the void structure inside the activated alumina is fully adsorbed and saturated, the activated alumina loses its adsorption effect at this time and needs to be replaced or regenerated. Today we will introduce the life cycle of activated alumina and how often the activated alumina is replaced. The adsorption performance of activated alumina balls is better because of its large surface area and uniform pores on the surface. However, in the course of use, the adsorption capacity of activated alumina balls will gradually decrease to the point that they cannot be effective. So how to judge that the activated alumina ball needs to be replaced? How long is the replacement cycle?
Generally, the service life of activated alumina balls is about 2-5 years. Of course, it is not completely certain, because the quality of the products of each manufacturer is different, there are good and bad, and the place of use is also different, because activated alumina balls are more widely used. , It can be used as a fluoride removal agent in water treatment, it can also be used as a desiccant for air compressor, or other fields, so it cannot be generalized.
We can look at the color when judging whether the activated alumina ball is replaced, because the color of the activated alumina ball is snow white, and it will turn yellow after a long time. If the color is particularly yellow, it needs to be replaced. In addition, it can be seen whether the humidity of the processed gas is too high. The activated alumina ball is used as a desiccant. There is also an activated alumina ball that can be used as a fluoride removal agent for high-fluorine drinking water (large fluorine removal capacity). If there is still fluorine in the water after treatment, or the fluorine content has not decreased, then the replacement period is up.
