Scale deposition potential and corrosion forming tendencies of the cooling water were monitored. Plant operating at high Holding Time Index contributed towards increased scale forming potential of cooling water. Corrosion data analysis showed slightly high rate of corrosion of cooling water that may be due to improper management of acid dosing in the system. Absence of side stream filtration unit might have supported increased turbidity in the system that helped increased growth of microbial colonies in the water. Cooling water quality standards did not support in keeping balance between corrosive and scale forming potential of the circulating water. Therefore, improved limits of cooling water quality standards have been suggested in this work.
