Zhongyang pioneered the activated carbon thermal disinfection and maintenance technology for dialysis water systems. The microporous structure of the activated carbon in the system is highly susceptible to invasion by source water colloids and microorganisms, resulting in a decrease in the activity of the activated carbon and posing risks to the system. Activated carbon thermal disinfection maintenance technology can effectively maintain the activity of activated carbon in the system, avoiding bacterial invasion of activated carbon and posing risks to the system.
