Method for treating wastewater

A system for treating wastewater comprising:

• an array of reactor tubes, each reactor tube comprising an outer cathode and an inner anode, the inner anode being positioned centrally within the outer cathode such that a spacing exists between an outer surface of the inner anode and an inner surface of the outer cathode, the inner anode comprising a non-donating material;
• a pump connected to an input of the array, the pump receiving influent wastewater and pumping influent wastewater into and through the series of reactor tubes such that the wastewater flows between the inner anode and the outer cathode;
• an injector connected to an input of the pump, the injector configured to add chloride salts to the influent wastewater;
• a power supply for supplying a voltage differential across the inner anodes and outer cathodes to generate chlorine based elements from chloride salts within the wastewater, wherein the chlorine based elements treat the wastewater;
• a feedback path to divert a portion of the wastewater with chlorine based elements back to an input of the pump such that the chlorine based elements are mixed with influent wastewater to increase the level of chlorine based elements available in the influent wastewater;
• and
• an oxidative reduction potential meter configured to measure the oxidative reduction potential of the treated wastewater, the meter configured to output a signal for controlling one or more of an amount of chloride salts that are added to the influent wastewater, a rate at which the pump pumps wastewater through the reactor tubes, a voltage level applied by the power supply, or an amount of wastewater that is diverted back through the feedback path.

A method for treating wastewater comprising:

• providing wastewater;
• providing an array of interconnected reactor tubes, each reactor tube comprising an outer cathode and an inner anode being positioned centrally within the outer cathode such that a spacing exists between the outer surface of the anode and the inner surface of the cathode, at least one of the inner anodes comprising a non-donating conductive material;
• injecting chloride salts into the wastewater;
• pumping wastewater with chloride salts into and through the array such that the wastewater flows between the inner anodes and the outer cathodes;
• applying a voltage differential to the anode and cathode of each reactor tube to generate chlorine based elements from the chloride salts, the chlorine based elements treating the wastewater to generate treated water;
• and
• diverting a portion of the treated water to an input of the array such that chlorine based elements contained in the treated water are supplied into the wastewater that is pumped into the array.
