CHLORINE DISINFECTION
Chlorination is the process of adding chlorine to water as a method of sanitizing and purifying it to prevent the spread of infection and disease. Chlorinated water systems require careful monitoring to ensure the correct conditions are achieved and maintained whilst operational and during the disinfections process.
Failure to achieve the correct chlorination levels in disinfections or sanitizing can lead to unsuccessful disinfections and conversely elevated levels can lead to potentially corrosive conditions.
