The advanced oxidation wastewater treatment module is basically a giant electrode assembly, EOU7240 forms an electrolytic wastewater treatment modular unit with electrolyzer shells, bench scale advanced oxidation wastewater treatment could be conducted on-site once electric current applied, as all the electrode materials are placed in the required positions and wastewater electrolysis is ready to run, MU724 advanced oxidation wastewater treatment module have left space for existing wastewater treatment system connection, piping, sampling, filters, as well as control fittings, switch/pause, and filter valves.
