Does adding trisodium phosphate to the boiler water increase or decrease the pH?
Thread Content
Everyone knows that trisodium phosphate is added to boiler water to remove scale, but recently I heard that it can also raise the pH of the boiler water. I’d like to know why; please help me understand this. Thank you
Trisodium phosphate is a compound that is strongly basic and weakly acidic; in water it exhibits basic properties, meaning its pH value increases.
The pH control of boiler feedwater is typically achieved by adding ammonia to raise the pH value of the feedwater
