When ice forms on the chlorine regulator, it indicates that there is an issue with the delivery of chlorine, specifically related to the pressure and temperature of the chlorine gas. Placing a second chlorine cylinder online is effective because it allows for the redistribution of the chlorine demand without overworking the existing cylinder. This additional cylinder can help ensure a stable chlorine residual even if one regulator is compromised due to icing.

This method addresses the problem directly by ensuring that there is an adequate supply of chlorine available, which can mitigate fluctuations in residual chlorine levels while allowing time for the affected cylinder and regulator to recover from the icing. Other methods, such as reducing the feed rate or increasing the temperature of the chlorine lines, may not effectively address the immediate problem of the ice formation and could lead to further issues with disinfection efficiency. Additionally, simply replacing the current chlorine cylinder might be unnecessary if the existing cylinder could resolve the icing issue with appropriate adjustments or additional support like another cylinder.
