Industrial park operators are often faced with poorly degradable wastewater resulting in low performance of the biological treatment. Despite this, information about COD fractions is not monitored due to the lack of a standard method and uncertainties in the experimental setup. This work represents a systematic screening of industrial wastewaters and suggests improvements on the test method.

The new frontier of industrial water reuse is the treatment of hard-to-treat wastewater generated by a variety of activities (e.g. pharmaceutical, electronics, chemical, mining, etc.). In this work we demonstrate that Electro-Fenton is a promising solution for the treatment of biorefractory and highly-concentrated wastewater from membrane fabrication, for which there is no gold standard.

Benzalkonium chloride (BACs) are used excessively in municipal wastewater reclamation RO processes in China, and they end up in RO concentrates at elevated levels. It was found for the first time that the combination of ozone and chlorine showed synergistic effects on the degradation of BACs.
