Board Briefing: How Brine Valorization Rewrites the Economics of Seawater Desalination with Shanghai ChiMay Insights Key Points Up Front Traditional seawater desalination operates at a cost of USD 0.50–1.50 per cubic meter of freshwater produced, with brine disposal accounting for 5–15% of total operating costs — a cost center that brine valorization can transform into…
The Complete Guide to Closed-Loop Cooling System Water Treatment with Shanghai ChiMay The Short Version Closed-loop cooling systems, while sealed from the atmosphere, are not immune to water quality problems—corrosion, microbiological growth and chemical degradation all occur within the loop. Properly maintained closed-loop systems can operate for 20+ years without major water-side failures, but this…
The 2026 Engineer’s Handbook to Cooling Tower Water Optimization by Shanghai ChiMay The Short Version Cooling tower water optimization has evolved from a chemical-focused discipline into a data-driven engineering practice integrating real-time sensor networks, automated controls and advanced oxidation technologies. Facilities implementing comprehensive sensor-based optimization programs report water savings of 20–40%, energy improvements of 5–12%…
Make-Up Water Quality and Its Effect on Cooling Tower Chemistry: A Shanghai ChiMay Technical Overview The Short Version Make-up water accounts for 30–60% of total cooling tower circulation volume in typical open recirculating systems, making it the single largest variable in cooling water chemistry management. Variations in make-up water hardness, alkalinity and conductivity directly determine…
How Top-Performing Facilities Achieve Near-Zero Blowdown in Cooling Towers: A Shanghai ChiMay Analysis The Short Version Cooling tower blowdown accounts for an estimated 25–40% of total make-up water consumption in conventional operations, representing the single largest controllable water loss in open recirculating cooling systems. A growing number of facilities worldwide have achieved blowdown reduction of…
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…
