1. A method for treating wastewater, the method comprising:

  • a) delivering a stream of the wastewater to a clarification subsystem in which organic matter and/or suspended solids are removed in a multi stage combined oxidation, coagulation, flocculation and filtration process and oxidizing organic matter and separating at least one of organic matter and suspended solids within the clarification subsystem to produce a clarified wastewater stream;

    b) delivering the clarified wastewater stream to a softening subsystem, causing precipitation of dissolved waste salts within the softening subsystem, and separating the precipitated waste salts to produce a softened wastewater stream;

    c) delivering the softened wastewater stream to a first reaction vessel, and injecting nano-sized bubbles of ozone and hydrogen peroxide into the second oxidized wastewater stream to produce an oxidized wastewater stream; and

    d) delivering the oxidized wastewater stream to a carbon filtration subsystem, causing decomposition of residual ozone in the oxidized wastewater stream, and separating trace residual organic matter from the first oxidized wastewater stream to produce a second oxidized wastewater stream;

    e) delivering the second oxidized wastewater stream to a first reverse osmosis subsystem and separating a first portion of remaining dissolved waste salts from the second oxidized wastewater stream within the first reverse osmosis subsystem to produce a first permeate wastewater stream.
