Cleaning protocols for microfiltration membranes vary according to the membrane tolerance to changes in which parameter and resistance to which chemical?

• A. Pressure and Chlorine
• B. pH and Oxidation
• C. Oxygen and Chlorine
• D. Temperature and Oxidation

Answer: (B)

Cleaning protocols for microfiltration membranes hinge on how chemically stable the membrane is to cleaning conditions. The most important factors are how much pH change the membrane can tolerate and how resistant it is to oxidation. During cleaning, acidic or basic cleaners shift the pH, and if the membrane’s pH tolerance is exceeded, it can degrade or lose performance. Similarly, oxidizing agents like chlorine are often used to remove organic fouling, but not all membranes withstand oxidation well, leading to damage or shortened life. Other parameters like pressure or temperature aren’t the primary chemical considerations driving cleaning choices, and oxidation resistance specifically addresses how the membrane handles the cleaning chemicals. So the best-fit combination is pH tolerance and resistance to oxidation.
