Hi Mr. MattThe main reasons for the unqualified KPI data of the factory are as follows: the factory did not adopt automatic blow down, resulting in high conductivity and turbidity, and Nalco sampling did not immediately detect, resulting in low residual chlorine data. I have also conducted cooling tower audit in most of the site this year and have already given the audit follow-up form to each site after each audit work. In the audit work, specific recommendation has been given to the site to improve the treatment performance especially on the below. Incorporate automation system for stable chemical dosing and consistent blow down Installing side stream filter for cooling tower that is close to dusty environment Proposing trial such as using Nalco 60612 to reduce on biocide dosage and operation cost Add corrosion rate coupon and adjust the system scheme according to the corrosion rate resultThanks. Please let me know if you have any question.
