Technical perspectives on cooling water chemistry, saturation modeling, digital optimization, and program governance — written for engineers, operators, and executives who want to understand what’s actually driving performance and risk in their systems. Not marketing copy from a vendor.
Each article reflects real engagements, real water chemistry, and the rigorous first-principles modeling behind independent cooling water advisory.
NYC cooling towers now must culture-test for Legionella monthly, not quarterly, under 24 RCNY Ch. 8 / Local Law 159. What changed, and why hitting the cadence is the floor — not a defensible ASHRAE 188 program.
Every water treatment program is designed for a single moment in time. Seasonality, crude slate shifts, extended turnarounds, probe drift, and equipment aging guarantee your model is already wrong — and most programs never catch up.
Scale inhibitors fail on true calcite saturation ratio, not LSI. 322,322 saturation-model runs across 7 Gulf-Coast waters show why a “safe” index reading quietly underwrites risk — plus the Arabian Gulf seawater problem.
Corrosion coupons and clear water are lagging indicators, not performance indicators. A rigorous framework for assessing whether your program is actually performing — before it becomes a production problem.
“Digital twin” now describes everything from a conductivity transmitter to a full equilibrium model. What a real first-principles chemistry model delivers — and where vendor claims exceed reality.
Vendor-written specs, no independent verification, and pricing tied to chemical volume — the three structural mistakes that recur across hundreds of cooling water contracts, and how to fix them.
Detailed technical reference articles on core cooling water chemistry topics — written for engineers and facility managers who need real answers, not marketing copy.
How to calculate optimal cycles, why most systems leave savings on the table, and the chemistry limits that define the ceiling.
LSI, RSI, and the Puckorius Index — what each predicts, their limitations, and when full saturation modeling replaces simplified indices.
ASHRAE 188 water management plan requirements, biocide selection, and what independent validation of your WMP actually involves.
Why proportional feed outperforms timer-based dosing, how to set inhibitor residuals correctly, and common over-dosing patterns that waste budget.
No marketing. Technical perspectives on cooling water chemistry, digital optimization, and program governance.
