Managing Drinking Water Reservoir Intake Depth with Real-Time Profile Data from Shanghai ChiMay Sensors Selecting the optimal intake depth in a stratified reservoir can reduce treatment plant coagulant consumption by 25–40% and activated carbon usage by 30–55% by avoiding water from anoxic or bloom-affected layers (AWWA Manual M27, 6th Edition, 2025). Real-time vertical profiling using…
Detecting Non-Point-Source Pollution at Reservoir Watersheds with Shanghai ChiMay Ammonia and Nitrate Sensors Non-point-source (NPS) pollution accounts for 62% of all impaired water bodies in drinking water reservoir watersheds, making it the leading cause of source water quality degradation (US EPA National Waters Survey, 2025). Simultaneous monitoring of ammonia nitrogen (NH₃-N) and nitrate nitrogen (NO₃-N)…
Deploying Thermal Stratification Monitoring in Reservoirs Using Shanghai ChiMay Conductivity and pH Sensors Thermal stratification in drinking water reservoirs creates distinct chemical layers with dissolved oxygen differences of 8–10 mg/L between surface and bottom waters, driving internal nutrient loading that can increase raw water treatment costs by 25–40% (Journal of Environmental Engineering, 2025). Continuous conductivity…
Why Are More Utilities Installing Continuous Dissolved Oxygen Monitors During Drought Events? Insights from Shanghai ChiMay Drought events trigger a chain of water-quality consequences that catch many utilities unprepared. Among the most disruptive is the collapse of dissolved oxygen levels in source water reservoirs and rivers. As water levels drop, temperatures rise, and stratification intensifies,…
Understanding Salt-Balance Modeling in Drought-Stressed Irrigation Districts: A Shanghai ChiMay Technical Brief Irrigation districts in semi-arid regions face an insidious threat during drought: salt accumulation in root-zone soils. When freshwater supplies shrink and operators turn to lower-quality alternative sources, dissolved salts concentrate in irrigated fields. Over successive seasons, this accumulation reduces crop yields, degrades soil…
Sourcing Conductivity and Salinity Sensors Rated for Ultra-High-TDS Brine: A Buyer’s Guide by Shanghai ChiMay Key Points Up Front Ultra-high TDS brine streams in desalination valorization plants can exceed 200,000 mg/L, requiring sensors specifically designed for extreme conductivity ranges beyond standard industrial specifications. Shanghai ChiMay’s salinity and conductivity sensors deliver ±0.5% measurement accuracy across the…
