2014-12-29 · Disadvantages of using hard water in boiler: The main destructive effects of using hard water in boilers are (i) formation of scales and sludges (ii) boiler corrosion (iii) using sodium phosphate as softening agent instead of sodium carbonate. Ii)by adding tannin, lignin to the boiler water, which UNIT I : WATER TECHNOLOGY
with a chelating agent is to tightly complex the calcium or magnesium, with the resulting reaction product being soluble. Although it is not the only chelating agent avail- able for boiler water treatment, the tetra sodium salt of ethylenediaminetetraacetic acid (EDTA) is typical of the chelating agents being used today. In addition, it is prob-
2017-3-10 · phosphate-free high-AVT water treatment after the removal of scale is also an effective measure. 3.

2018-1-22 · Using the Bru’n Water Spreadsheet, I determined the amount of table salt needed to add 100 ppm sodium to one batch while keeping the other at my typically low levels. Note: since table salt also adds chloride ions, its use in the high sodium batch produced a difference in that particular mineral.
What is trisodium phosphate used for in food. In the field of food, trisodium phosphate is used as a quality improver, which has the effect of improving the capability of complex metal ion, pH value and increasing the ionic strength, thereby improving the kneading strength and water holding capacity of the food.
2015-9-29 · Boiler Water Treatment . In the 1930s as steam generator technology evolved and high-pressure units grew in numbers, tri-sodium phosphate (TSP, Na 3 PO 4) became the common chemical for boiler water treatment as it generates alkalinity (caustic, NaOH) to protect against corrosion. Also, phosphate reacts with hardness compounds to reduce the
Boiler feedwater at power plants is kept slightly alkaline (pH ca. 9.0) as an anticorrosion measure. Phosphate is widely used as an agent for adjusting the pH of the water in medium, high and ultrahigh pressure boilers.
