Case Brief: PbO2-Coated Anodes for Wastewater Oxidation Testing

Project background

An industrial wastewater enquiry involved oxidation testing under saline or complex water conditions. Typical relevant projects include wastewater treatment companies, pilot-test builders and EPC contractors that need to clarify COD composition, chloride concentration, test current density and target discharge standard before selecting PbO2-coated anodes.

Key technical questions

• What are the COD, salinity, chloride concentration, pH, temperature and target discharge requirements?
• Is the project at laboratory testing, pilot testing or engineering design stage?
• What current density, electrode spacing, flow pattern and power-supply range are available for testing?

TJNE review and supply scope

• PbO2-coated titanium anodes and related electrode configuration review
• Suggested input data list for laboratory or pilot testing
• Electrochemical unit discussion when cell configuration is part of the scope

Result / next step

The enquiry moved toward a water-quality and test-condition review before selecting electrode type, sample size or pilot-unit direction, reducing the risk of judging oxidation performance by anode material alone.
