Abstract: A vacuum airlift system for treating an aqueous effluent includes an upflow liquid portion, where the upflow liquid portion is configured to retain a fluid, and a fluid inlet, the fluid inlet being fluidly coupled with the upflow liquid portion, where the fluid inlet is positioned at about a bottom of the upflow liquid portion. The vacuum airlift system can also include a downflow liquid portion, where the downflow liquid portion is fluidly coupled with the upflow liquid portion, and a fluid outlet, the fluid outlet being fluidly coupled with the downflow liquid portion, where the fluid outlet is positioned at about a bottom of the downflow liquid portion. The vacuum airlift system can also include a plurality of aerators fed by one or more fluidic oscillators; the plurality of aerators being coupled to the upflow liquid column.
