How should the capacity of disinfection equipment be calculated by TCEQ standards?

At least 25% of the highest dosage
At least 50% greater than the highest expected dosage
Equal to the average expected dosage
At least 75% above the projected dosage

The correct answer is: At least 50% greater than the highest expected dosage

The capacity of disinfection equipment should be calculated to ensure that it can handle the highest expected dosage effectively. Choosing at least 50% greater than the highest expected dosage is crucial because it provides a buffer that accommodates variations in water quality, flow rates, and any unforeseen increases in microbial load. This approach ensures that the treatment system remains effective even under challenging conditions, thereby preventing the risk of insufficient disinfection, which could lead to contamination of the water supply. By calculating the capacity this way, operators can guarantee that the system is robust and can respond adequately to fluctuating demands, ultimately protecting public health and adhering to regulatory requirements set by the TCEQ. This standard balances adequacy with safety, which is vital for maintaining safe drinking water standards.
