The Historical Model and Why It Worked—Until It Didn’t For most of the past century, cooling tower water treatment followed a straightforward formula: add biocide, add scale inhibitor, add corrosion inhibitor, test the water periodically and adjust doses based on laboratory results. This chemical-only approach was good enough to keep industrial operations running, and it…
The Complete Guide to Closed-Loop Cooling System Water Treatment with Shanghai ChiMay Closed-loop cooling systems are sealed from the atmosphere, but that doesn’t make them immune to water quality problems. Corrosion, microbiological growth and chemical degradation all happen inside the loop—silently. Maintained properly, a closed-loop system can run 20+ years without major water-side failures, but…

The 2026 Engineer’s Handbook to Cooling Tower Water Optimization by Shanghai ChiMay The numbers tell the story: facilities running comprehensive sensor-based optimization programs report water savings of 20–40%, energy improvements of 5–12% and chemical cost reductions of 25–35%. Cooling tower water optimization has moved from a chemical-focused discipline to a data-driven engineering practice—real-time sensor networks,…
When engineers discuss cooling tower optimization, attention typically focuses on the recirculating water itself—its temperature, its chemistry, its biological load. But the quality of water entering the system, known as make-up water, is equally important. Make-up water is the largest external input to the chemistry of an open recirculating loop: every liter of water lost…
AOP retrofits are picking up steam in industrial cooling, driven by water scarcity, chemical cost pressure and tighter discharge rules. The Cooling Technology Institute has described AOP-based treatment as a way to keep cooling tower water cleaner and more stable, with fewer operational variables. But an AOP retrofit is not a drop-in swap. It changes…
