What percentage greater than the highest expected dosage must the disinfection capacity provide?

Twenty-five percent

Fifty percent

The idea is to build a safety margin above the maximum dose you expect to use. In basic water treatment, you want the disinfection system to have enough capacity to handle variations in flow, measurement, and conditions so the disinfectant level remains effective throughout the system. A fifty percent buffer means the system should be able to deliver 1.5 times the highest anticipated dose. This amount typically covers short-term peaks and small feed fluctuations without paying for twice as much capacity. A smaller margin (like twenty-five percent) may not handle peaks or errors, while larger margins (seventy-five or one hundred percent) add unnecessary cost. So, fifty percent provides a practical balance.

Seventy-five percent

One hundred percent
