Non-Chemical Water Treatment for Cooling Towers: A Practical Guide
A technical comparison of non-chemical cooling tower water treatment methods — magnetic conditioning, ozone, pulsed power, electrochemical, and more — and where the SKW System fits.
Conductivity vs. Fluorescence for Sugar Leak Detection in Boiler Condensate
Sugar mills have relied on hourly manual condensate sampling for decades, precisely because a sugar leak into boiler condensate is expensive and dangerous to leave undetected. The problem is that manual sampling and conductivity-based online monitoring share the same underlying weakness: neither one is sensitive enough to catch a leak while it’s still small, so […]
Condition-Based vs Outcome-Based Cooling Tower Water Treatment: Measuring the Result Instead of the Recipe
A cooling tower can run within every setpoint on the controller — conductivity in range, pH in range, ORP in range — and still be forming scale, growing biofilm, and corroding the heat exchanger. That’s not a contradiction. Conductivity, pH, and ORP were never measuring those failures directly. They were measuring conditions that make those […]
Why Wait Until Algae Is Visible? Early Chlorophyll-A Detection in Cooling Tower Water Treatment
Algae is one of the few cooling tower problems a water treatment provider doesn’t strictly need a sensor to find — green slime on the basin walls or a film across the fill media is visible to anyone who looks. That’s exactly the problem. By the time it’s visible to you on a service visit, […]
PTSA and Tagged Polymer Sensors: Two Different Things Being Measured, Not Two Versions of the Same Test
Ask most operators what a PTSA sensor and a tagged polymer sensor do, and the honest answer is usually “they both check the inhibitor.” That’s true in the loosest sense, but treating them as interchangeable misses why cooling tower programmes across Malaysia increasingly run both rather than picking one. They measure two genuinely different things. […]
Testing Tolyltriazole in Chiller Water Treatment: Color Disc Kits vs. Reagent-Free Handhelds
Closed-loop chiller systems protect their copper and brass surfaces with a passivating film built by tolyltriazole (TTA), and that film only works if there’s enough TTA in solution to maintain it. Let the residual drop without noticing, and copper corrosion starts quietly — no bleed event, no visible fouling, just slow metal loss on evaporator […]
Corrosion Coupons vs. Corrosion Rate Sensors: Why Waiting 90 Days to Find Out Is a Problem
Most cooling tower and chiller operators find out about a corrosion problem in one of two ways: a coupon comes back from the lab with a number that’s already 60 or 90 days old, or a leak develops and the corrosion has already been happening for months. Both are after-the-fact. Neither tells you what was […]
Why Your pH Reading Keeps Drifting: The Reference Electrode Problem Nobody Talks About
Every time a pH reading drifts, the glass bulb gets blamed. The operator recalibrates, the drift comes back within days, and eventually someone replaces the whole sensor. Nine times out of ten, the glass electrode was never the problem — a pattern we see repeatedly across process plants in Malaysia. The reference electrode is. Across […]
Hydrofluoric Acid and Standard pH Sensors: Why Glass Electrodes Fail and What to Use Instead
Put a standard glass pH electrode into a hydrofluoric acid stream and you are on a countdown. It might read fine for a few days. Then the slope drops, the response slows, and eventually the bulb itself starts to look etched or frosted. By the time someone pulls the sensor for inspection, the glass is […]
Why Fixed-Rate Coagulant Dosing Fails Variable Influent Flow — And How the Atlanta’s ppm Mode Solves It
Coagulant and polymer dosing only works when the dose scales with flow. Here’s how the Atlanta’s ppm Mode ties dosing directly to a flow meter, and what happens when demand exceeds the pump’s own maximum.
