Dissolved and suspended solids in boiler water are kept at minimum levels by __________.

Question 1 of 27070

Dissolved and suspended solids in boiler water are kept at minimum levels by __________.

🔍 Key Concepts

• Boiler blowdown and how it removes concentrated impurities • Difference between dissolved/suspended solids vs. gases like oxygen • Purpose of chemical treatment (phosphates, oxygen scavengers, volatile chemicals) in boiler water

💭 Think About

• Which process physically removes water that is rich in solids from the boiler and replaces it with fresher feedwater? • Do phosphates and oxygen scavengers remove solids from the system, or do they mainly change the form/behavior of impurities already present? • Which option directly reduces the total amount of solid material in the boiler water, rather than just conditioning or preventing specific types of corrosion or scale?

✅ Before You Answer

• Identify which choice involves actual discharge of water and solids from the boiler • Distinguish between treatments that condition impurities versus those that remove them • Confirm which method is primarily used to control total dissolved solids (TDS) and suspended solids, not just corrosion or pH
