Activated carbon has several problems in water treatment

Activated carbon (GAC) has been widely used in the conventional and deep treatment of water. Due to its own physical properties - extremely strong adsorption ability, it can be used to adsorb unpleasant smells, chlorine, and dye in water. It has become one of the most mature and effective methods for removing organic pollutants in water. Research by Tsinghua University in China has found that activated carbon can also remove mutagenic substances produced by chlorination in water.

However, there are unsolvable problems with activated carbon in water treatment, especially in purification equipment used for drinking water deep treatment. That is, the self-pollution of the activated carbon medium. It is like a super sponge, absorbing a large amount of toxic and harmful pollutants while breeding a large number of bacteria in its pores. Experimental results show that when the activated carbon filter is used for a certain period of time, the activated carbon adsorbs a large amount of organic pollutants, and the chlorine with bactericidal effect no longer exists. At this time, microorganisms are easily reproduced; organic matter decomposes on the interface between the activated carbon and microorganisms, gradually decomposing organic nitrogen into protein nitrogen, ammonia nitrogen, and nitrite nitrogen, resulting in an increase in the nitrite content in the effluent of the activated carbon filter. This not only fails to purify the water quality, but also pollutes the water quality. Our company can provide more news information to consumers at http://www.vikenton.com
