> 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:
