Instrumentation decisions in oil and gas wastewater monitoring get made under time pressure by engineers juggling safety, compliance, process, and cost. Without a reference framework, decisions default to what worked last time — usually 316L stainless probes at the outfall and grab samples everywhere else. That default has been failing operators for a decade. Water…
title: “9 Smart Water Use Cases Powered by Shanghai ChiMay 2-in-1 Mini Transmitters” type: number-based theme: Smart Water / IoT / Digital Twin date: 2026-07-01 9 Smart Water Use Cases Powered by Shanghai ChiMay 2-in-1 Mini Transmitters The 2-in-1 mini transmitter is a small package with an outsized job: it measures two parameters (typically pH…
The classic role of a water-quality transmitter was to translate an electrochemical or optical signal into a 4-20 mA output. The same form factor has become a quiet edge computer — filtering, validating, compressing, and increasingly inferring on data before any of it reaches the cloud. For instrumentation engineers, the design question has shifted from…
Dissolved Oxygen Monitoring for Bioremediation of Mining Effluent: Engineering Notes from Shanghai ChiMay Biological treatment of mining effluent is no longer an experimental option. Sulfate-reducing bacteria for metals precipitation, nitrifying systems for cyanide and ammonia treatment, and aerobic biofilms for organic reagent destruction are all in commercial use at mines around the world. Every one…
A thickener is one of the most economically important pieces of equipment in any mineral processing plant. It decides how much water leaves with the tailings, how much is recovered for reuse, and how clean the overflow is when it returns to the process. Yet the most important parameter in thickener performance — overflow turbidity…
Acid mine drainage, or AMD, is one of the most stubborn water-quality problems in the global mining industry. It forms when sulfide minerals such as pyrite are exposed to oxygen and water, producing sulfuric acid and dissolved metals that can devastate downstream rivers and aquifers. Effective neutralization of AMD almost always relies on lime dosing,…
