What is the minimum capacity requirement for disinfection equipment in a treatment plant?

The minimum capacity requirement for disinfection equipment in a treatment plant is at least 50% greater than the highest expected dosage. This standard ensures that the disinfection system has sufficient capacity to effectively eliminate pathogens and other contaminants under varying conditions.

Having a capacity that exceeds the highest expected dosage helps to account for fluctuations in water quality, variations in flow rates, and the potential for ineffective disinfection due to unforeseen circumstances. This extra margin ensures that even during peak demands or under less than ideal conditions, the disinfection process remains efficient and compliant with health and safety standards. By ensuring the capacity is higher than the typical needs, treatment plants can maintain effective disinfection performance while also reducing the risk of treatment failures that could arise from unexpected changes in water conditions or treatment requirements.
