🔍 Key Concepts

• Boiler water salinity control methods • Difference between chemical treatment vs mechanical removal of dissolved solids • Role of continuous vs intermittent blowdown in boiler operation

💭 Think About

• Which option directly removes dissolved salts from the boiler water, rather than just changing their chemical form or controlling other impurities? • Which treatments listed are mainly used for controlling oxygen corrosion or precipitating hardness, and do they actually lower salinity? • Think about what a chief engineer would adjust on the boiler if the conductivity (TDS) reading became too high.

✅ Before You Answer

• Identify which choice is a mechanical process instead of a chemical additive or firing adjustment. • Ask: does this option specifically help reduce total dissolved solids (TDS)/salinity? • Eliminate any answers that mainly address oxygen control or hardness precipitation rather than direct salt removal.
