Simplified answer, yes and yes. Complex wastewater could be treated with electrochemical avanced oxidation processes technology, experiments, on-site field testing and treatability assessments, data and performance analysis results from previous projects originate from us and other suppliers have demonstrated electrochemical advanced oxidation processes is efficient, and effective, suitable for wastewater remediation and reuse, it’s a cost effective and sustainable, eco-friendly treatment method for complex wastewater treatment. Electrochemical advanced oxidation treatment technology was employed as pretreatment prior to biological treatment to increase biodegradability of polluted water, which makes it an ideal treatment technology to couple with other technology to treat complex wastewater, especially industrial effluents which are bio-refractory (low BOD/COD ratio), highly toxic, high salinity, and highly concentrated, high chemical oxygen demand (COD), and then tertiary treatment/polishing for further removal of chemical oxygen demand (COD), coloration and etc, to meet discharge standard and comply with environment regulations. This electrochemical oxidation wastewater treatment unit is a commercially available modular treatment system, it could operate in harsh environment, under regular pressure and temperature, and handle different flow rates.
