HOCL, NSC and Surfactant for Cooling Water Systems/Cooling Towers
Using hypochlorous acid in cooling water systems of power plants is a common practice for controlling microbial growth, preventing biofilm formation, and inhibiting corrosion.Here’s how it’s typically used and its effects:Corrosion Inhibition:While hypochlorous acid itself can be corrosive in high concentrations, when used properly and at appropriate levels (typically around 0.5 to 2.0 ppm), it can help inhibit corrosion by controlling microbial populations. By preventing biofilm formation and microbial activity, hypochlorous acid indirectly reduces the likelihood of corrosion in the cooling water system.pH Consideration:It’s essential to monitor and control the pH of the cooling water when using hypochlorous acid, as its effectiveness as a biocide depends on the pH level. Typically, maintaining a slightly acidic pH (around 6.5 to 7.5) optimizes the performance of hypochlorous acid while minimizing corrosion risks.Monitoring and Control:Regular monitoring of hypochlorous acid levels, pH, and corrosion rates is crucial to ensure effective and safe operation of the cooling water system. Automated control systems may be employed to maintain appropriate chemical levels and conditions within the system.Cleaning cycle:Take samples for analysis prior to treatment.Include: sulfate reducing bacteria, general aerobic bacteria, and acid producing bacteria or similar measurements
