What happens if the feed rate is too high in a chlorination system?

In a chlorination system, if the feed rate of chlorine is too high, the primary concern is the potential for producing harmful concentrations of chlorine in the water. This excess feed can lead to an increase in free chlorine levels, which can indeed make the water toxic to aquatic life and humans if the levels exceed safe drinking water limits.

High chlorine levels may not directly cause chlorine to freeze, as this is unlikely given chlorine's properties. Instead, chlorine gas could react with water and create harmful by-products or impart a strong chlorine smell and taste, which can deter water consumption. This underscores the importance of maintaining an appropriate feed rate to ensure both the safety and palatability of the water being treated.

Monitoring and adjusting the feed rate are crucial components in chlorine disinfection processes to avoid creating unsafe conditions instead of causing physical changes like freezing.
