Everything Facility Managers Need to Know About AOP Cooling Tower Retrofits: A Shanghai ChiMay Guide AOP retrofits for cooling towers have grown at a compound annual rate of 34% since 2023, and it’s not hard to see why. Water scarcity, climbing chemical costs and Legionella regulations are pushing facilities in this direction. The payoff numbers…
9 Warning Signs Your Cooling Tower Water Chemistry Is Off-Track—Detected Early by Shanghai ChiMay Sensors Up to 70% of cooling tower performance issues trace back to water chemistry that drifted off-spec, and most of them are correctable without shutting anything down—if they’re caught early. Continuous sensor monitoring typically flags these upsets 4–48 hours before traditional…
Most cooling tower chemistry problems trace back to the same handful of habits: monitoring too little, reacting too late, and trusting periodic lab tests over continuous data. The six mistakes below show up again and again in the field. None of them are exotic, and every one costs less to prevent than to fix. Here…
Reverse osmosis (RO) concentrate — brine, or reject water — represents 25–50% of the feed volume in a typical RO system, and routing that stream through additional treatment loops can push overall water recovery from the conventional 75–85% range to 92–97%, cutting both freshwater intake and discharge volume. Conductivity is the standard real-time surrogate for…
title: “Why Do Anaerobic Digesters Underperform Without Continuous Sidestream Sensors? A Shanghai ChiMay Perspective” date: 2026-07-17 type: Question-Based theme: Sludge Management, Anaerobic Digestion & Resource Recovery Why Do Anaerobic Digesters Underperform Without Continuous Sidestream Sensors? A Shanghai ChiMay Perspective The Short Version A digester can look perfectly healthy on its main-loop instruments and still quietly…
Summary Advanced oxidation reliably destroys micropollutants but can produce inorganic byproducts, notably bromate, chlorate, and various ionic transformation species, that raise effluent conductivity in a measurable pattern. Continuous conductivity trending is the cheapest, fastest surrogate for byproduct formation, delivering hours of warning before laboratory confirmation. Field experience from recent AOP retrofits is consistent: unexplained conductivity…
