Abstract
Water decontamination systems including aerator modules are described herein. Such systems are capable of removing contaminants, including volatile organic compounds, from the water. Certain volatile organic contaminants can be removed at high efficiencies. The systems may be automated to remove the contaminants and produce cleaned water on a continuous basis.

An apparatus for reducing levels of contaminants in a contaminated liquid comprising a tank, wherein the tank comprises:
- an inlet for introducing a contaminated liquid to the tank;
- an outlet for outputting an output liquid having less contaminants than the contaminated liquid,
- a lid for preventing gaseous contaminants from the contaminated liquid to escape to an atmosphere surrounding the tank;
- a plurality of first and second partitions disposed between the inlet and the outlet, each of the first partitions extending from the lid to a first level above a bottom of the tank, and each of the second partitions extending from the bottom of the tank to a second level below the lid of the tank, the plurality of first and second partitions forming a plurality of chambers through which the contaminated liquid flows;
- a vent positioned between the second level and the lid for removing the gaseous contaminants;
- a vacuum source connected to the vent;
- and
- at least one gas output configured to deliver a gas to a contaminated liquid located within each chamber of the tank.
An apparatus for reducing levels of contaminants in a contaminated liquid, the apparatus comprising a tank, wherein the tank comprises:
- a headspace connected to a vacuum source;
- at least one countercurrent flow chamber having a first inlet side, a first outlet side, and a gas source output for delivering gas to a contaminated liquid, and
- at least one current flow chamber in fluid connection with the at least one countercurrent flow chamber, the at least one current flow chamber having a second inlet side and a second outlet side;
- and
- wherein the distance between the first inlet side and the first outlet side of the countercurrent flow chamber is greater than the distance between the second inlet side and the second outlet side of the current flow chamber.
