Water treatment system and method

A method for treating an influent water in each stage of a multiple stage processing unit, the method comprising:

• degassing the water by saturating the water with air;
• stripping volatile compounds from the water;
• evaporating non-aqueous phase liquid petroleum from the water;
• decarbonating the water, and killing or inactivating volatile microbes in the water.

A system for treating produced water, the system comprising:

• a multiple stage processing unit, wherein each stage comprises:
• a fluid mobilization unit comprising:
• a fluid chamber having at least one partition;
• a fluid inlet attached to the chamber;
• a pump;
• and
• a fluid outlet;
• and
• a fluid processing component comprising:
• a degassing sump, the sump having a water outlet;
• a stripper positioned above the sump, the stripper having at least one water inlet operatively connected to the fluid outlet;
• an air inlet adjacent the stripper;
• a gas exhaust adapted to circulate gases from the sump to the stripper;
• wherein the pump operates to move fluid from the fluid chamber to the water inlet of the processing component;
• and
• a regenerative thermal oxidizer;
• a clarifier unit;
• an ultraviolet irradiation unit;
• and
• a filtration unit;
• wherein exhaust gases from a first stage of the processing unit are circulated to the thermal oxidizer;
• and
• wherein influent water is adapted to be supplied to the fluid inlet of the first stage;
• and
• wherein fresh air is adapted to be supplied to the air inlet of a final sixth stage of the processing unit.
