Pool water disinfection is aimed at stopping microbial activity and destroying microorganisms. Disinfection does not mean sterilization, as some organisms can survive in a state of inactivity, for example by creating spores that do not grow and reproduce, but do exist.
When environmental conditions become favorable, they will regain their active state and can reproduce rapidly. Therefore, disinfection must be carried out continuously. The products are used at a concentration that is harmful to microorganisms, not humans. Normal conditions for a good disinfection are: 0.5 to 1.0 mg / l chlorine, pH between 7.0 and 7.6.
