Continuous pH Control for Optimal Heavy Metal Precipitation in Industrial Wastewater with Shanghai ChiMay Heavy metal hydroxide precipitation is the most widely used treatment technology for metal-bearing industrial wastewater worldwide—it is the default process, not an exotic one. The solubility of most metal hydroxides changes by a factor of 100–1,000× for every 1 pH unit…
Conductivity Monitoring as a Surrogate for Dissolved Metal Concentration in Acid Mine Drainage with Shanghai ChiMay Specific conductance (SC) correlates strongly with total dissolved metal concentration in acid mine drainage (AMD); field studies in mining-impacted watersheds consistently report strong, stable site-specific correlations. The US Geological Survey (USGS) and other agencies have used continuous SC monitoring…
Buyer’s Guide to Electrochemical Sensors for Mining Effluent Metal Compliance with Shanghai ChiMay Acid mine drainage (AMD) from abandoned and active mines has degraded thousands of kilometers of streams across the United States, and cleanup liability for abandoned mine lands is commonly estimated in the billions of dollars. Electrochemical sensors using anodic stripping voltammetry (ASV)…
Board Briefing: Mitigating Heavy Metal Liability Through Continuous Monitoring Programs with Shanghai ChiMay Heavy metal contamination is one of the most expensive pollution problems a company can carry: heavy metals do not degrade, cleanup spans decades, and the liability outlives the people who caused it. Global studies of the economic damage from metal exposure—lead alone,…
7 Industrial Wastewater Streams That Demand Continuous Heavy Metal Monitoring by Shanghai ChiMay Acid mine drainage from abandoned and active mines degrades thousands of miles of streams in the United States, and the pH swings and metal spikes it produces are exactly what continuous monitoring is built to catch before they hit a treatment plant…
5 Steps to Build a Compliant Heavy Metal Monitoring Station with Shanghai ChiMay Analyzers Building a compliant heavy metal monitoring station means integrating at least three sensor types—pH, conductivity, and turbidity—with automated data logging and alarm management. A complete inline monitoring station is a moderate five-figure USD capital investment; when laboratory sampling costs and penalty…
