1. A method for treating water, the method comprising:
supplying influent water to a multiple stage processing unit;
processing the water in each stage of the multiple stage processing unit by performing each of the steps of:
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;
subliming semi-solids from the water;
resolving emulsions in the water; and
breaking colloids in the water using continuous cavitation; and
depositing and ripening petroleum solids;
wherein each stage of the processing unit is connected in series to an adjacent stage; and
wherein a portion of the water from a given stage is circulated to a fluid inlet of a subsequent stage; and
wherein gas emissions from a given stage are circulated to a gas inlet of a preceding of stage;
clarifying the water discharged from the multiple stage processing unit through floatation and sedimentation;
inactivating volatile microbes in the water discharged from the processing unit;
filtering the water discharged from the processing unit; and
combusting gaseous emissions.
