The MUF system processes feedwater from which source before demineralization?

• A. Reserve feed tanks
• B. Condenser
• C. Boiler feedwater tank
• D. Lube oil tank

Answer: (A)

The Make-up Filtration (MUF) system is designed to treat makeup water that will become boiler feedwater, and its source is the reserve feed tanks. These tanks hold the untreated makeup water that the MUF conditions—filtration, chemical dosing, and pre-treatment—before it goes on to demineralization and then the boiler. This setup provides a stable, controllable supply of feedwater that isn’t tied to the condensate return loop. The condenser produces condensate that’s already part of the return system, not makeup water to be treated by the MUF; the boiler feedwater tank would hold water after treatment, not the raw source for MUF; and the lube oil tank is unrelated to feedwater treatment.
