The system’s energy requirements vary depending on the wastewater’s conditions, such as contaminant concentration, water matrix, or the customer’s discharge requirements. In one of Oxyle’s full-scale units that treats 10 cubic meters per hour, energy consumption measured less than 1 kilowatt-hour per cubic meter, according to the company.
Using the flow of water, rather than electricity, to activate the reaction makes the method far more energy efficient than other approaches, says Mushtaq.

Different approach with no energy/volume (kWhr/m^3) metric in the abstract:
