Conclusions:
Using experimental results from this study, a commercial scale single-pass reactor was designed to pre-treat chrome plating wastewater. A comparison of the operating and installation costs of the OxByEl process versus carbon adsorption, ion exchange and a low- cost recirculating batch electro-oxidation process was made. The OxByEl electro-oxidative system was the lowest cost treatment method validating its commercial advantage. Further optimization of the reactor design, electrode design and operating parameters will result in continued reduction in both operating and capital costs. A main technical advantage of the OxByEl process is its reactor and electrode scalability. For large volume of wastewater, the reactor footprint is small and big tanks required for batch processes with long residence times are not required. Other advantages are that the reactor runs at room temperature, can be automated, the process is not sensitive to incoming pH, does not require chemicals, can treat foaming PFAS and its low cost electrodes are durable.
