- May 31, 2019-

The disinfecting commodity commonly used in swimming pools is sodium dichloroisocyanurate. Good disinfection effect, it is a new high-efficiency swimming pool disinfectant. It has the two-layer sterilization and disinfection characteristics of chlorine-based and oxygen-based preparations, and has remarkable effects; it can strongly kill various pathogenic microorganisms such as cell spores, bacterial proliferators, fungi, etc., and has a special killing effect on hepatitis virus and prevalent liver virus. It can quickly kill and strongly control algae such as indigo green algae, red algae and seaweed. The efficacy of the drug is stable and lasts for a long time; the disinfection of the swimming pool disinfectant is 50~85 times that of sodium hypochlorite. The disinfection agent of the swimming pool is small, the use is simple, no residual poison and side effects, and it is safe for people. It is an ideal disinfectant commonly used in swimming pools.


The advantages of sodium dichloroisocyanurate for disinfection of swimming pool water are as follows:

(1) Sodium dichloroisocyanurate is a strong oxidant rather than a chlorinating agent.

(2) Its bactericidal effect is relatively good,

(3) Degrading a carcinogenic fused ring compound into a non-carcinogenic substance;

(4) Sodium dichloroisocyanurate does not react with ammonia to form chloramine, and trihalomethane formed by reaction with organic matter is much less than liquid chlorine.
