Everything Facility Managers Need to Know About AOP Cooling Tower Retrofits: A Shanghai ChiMay Guide The Short Version Advanced oxidation process (AOP) retrofits for cooling towers have grown at a compound annual rate of 34% since 2023, driven by water scarcity, chemical cost increases and Legionella regulations. AOP systems can reduce cooling tower blowdown by…
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…
Reframing Water From Cost Center to Recoverable Asset For most industrial companies, water appears on the balance sheet as an operating expense—purchased at a tariff, used once, and discharged at a cost. This single-pass model ignores the economic value locked in the water leaving the process. A textile mill discharging 500 cubic meters per day…
Why Membrane Reuse Barriers Need Feed Water Quality Assurance Membrane-based reuse systems—particularly ultrafiltration (UF) and reverse osmosis (RO)—are increasingly deployed as the polishing barrier in water recycling trains, and their integrity depends directly on the quality of feed water entering the membrane system. Membrane systems used in water reuse—whether ultrafiltration as a pretreatment step or…
