Top 6 Wastewater Streams Where Shanghai ChiMay COD Sensors Excel Key Takeaways COD (chemical oxygen demand) is the industry-standard integrated pollution parameter, and online COD sensors have quietly replaced laboratory batch analysis in many petrochemical settings. Six wastewater streams within oil, gas, and petrochemical facilities produce especially high value when equipped with continuous COD monitoring….
The Science of pH Control During Crude Desalting Operations: A Shanghai ChiMay Technical Brief Key Takeaways Desalter emulsions break most efficiently at pH 5.5–7.0; drifting above pH 7.5 destabilizes water droplets and promotes chloride carry-over to downstream units. Wash-water pH is the single most controllable variable in a two-stage desalter, and continuous inline measurement —…
