Scaling issues
Challenge
Unstable cycles of concentration caused recurring heat-exchanger scaling, hurting unit efficiency and raising maintenance cost.
Solution
Online conductivity triggers auto blowdown; antiscalant is dosed proportionally to makeup by metering pumps with online pH trim.
Results
- Zero scaling events
- COC held at the economic 4-5 band
- Cleaning costs slashed
