Abstract
Devices, processes, systems, and articles of manufacture adapted to treat contaminated fluid, such as organic wastewater, are described. These are described to include lifting contaminated fluids, treating contaminated fluids, or both, through gas application. In certain designs, gas, such as pressurized air, may be used to lift contaminated fluids, such as organic wastewater (i.e., water having contaminating organics of some kind, e.g. residential septic wastewater). In certain designs, gas, such as pressurized air, may also be used to treat fluids interfacing with the gas.
