What is the concentration of chlorine recommended when used with hot water for disinfection?

The recommended concentration of chlorine when used with hot water for disinfection is typically around 25 mg/L. This level is effective in achieving the necessary microbial reduction when applied correctly and is often suggested for food contact surfaces in food safety protocols. Chlorine acts as a powerful oxidizing agent and is widely utilized in sanitizing processes due to its ability to kill bacteria and other pathogens.

Using a concentration of 25 mg/L strikes a balance between effective disinfection and safety, ensuring that the chlorine does not exceed levels that could be harmful or lead to undesirable chemical residues. Lower concentrations may not provide adequate disinfection, while higher concentrations could pose health risks or cause damage to certain materials. Therefore, maintaining chlorine levels at approximately 25 mg/L is optimal for disinfection when combined with hot water.
