Florida Drinking Water Operator "B" Practice Test

What is the name of the test performed on membrane filtration units to verify their performance according to manufacturer design?

1. Pressure test

2. Membrane integrity

3. Flow rate test

4. Contaminant test

The correct answer is: Membrane integrity

The test performed on membrane filtration units to verify their performance according to the manufacturer's design is known as the membrane integrity test. This test is essential for ensuring that the membrane is functioning correctly and maintaining its barrier properties. An intact membrane is critical for effective filtration, as it prevents the passage of contaminants while allowing water to flow through. The membrane integrity test checks for any breaches or failures in the membrane that could compromise the treated water quality. It typically involves methods such as pressure hold tests or bubble point tests, which assess if the membrane can withstand specified pressures without allowing unfiltered water or contaminants to pass through. Successfully passing this test indicates that the membrane is in good condition, ensuring the reliability of the filtration system. Understanding membrane integrity is crucial in the context of drinking water treatment, as the membranes play a key role in removing impurities and ensuring safety for consumers. Hence, this test is a standard procedure in maintaining the health and trustworthiness of water supply systems.
