TSP / Trisodium Phosphate as antiscalant in industrial cooling water systems. TSP as antiscalant may also influence the corrosion in cooling water systems.
The pH of all cooling waters was maintained at 6.5 by adding sodium hydroxide or glacial acetic acid as solution per requirement.
TSP is a good corrosion inhibitor and provide 99 % percent protection from corrosion. It was observed that percentage inhibition efficiency of corrosion inhibitor increases with increase of concentration of TSP from 10 to 100 ppm.
Conclusion :
Instead of adding too much chemicals i.e : antiscalant , corrosion inhibitors, dispersant, biocides, pH booster, and hardness stabilizers to cooling water, a single chemical with solves both the problems of scaling as well as corrosion can be used. TSP provides both antiscaling as well as good corrosion protection of carbon steel in various investigated synthetic cooling waters.
