Abstract:
1. A method for treatment of a fluid, comprising: placing a diffuser for diffusing a gas into a fluid; providing the gas to the diffuser; and diffusing the gas into the fluid, wherein diffusing with the diffuser comprises: flowing the fluid from a first inlet substantially without interruption into a first end of a channel formed between a first side of a first member and a first side of a second member; flowing the fluid from the first end through the channel to an outlet proximate to a second end of the channel; while the fluid is flowing through the channel, moving the second member with respect to the first member; while the second member is moving with respect to the first member, flowing the fluid over surface disturbances comprising at least one of depressions or protrusions and a plurality of second inlets formed therein, formed in at least the one of the first side of the first member and the first side of the second member and thereby generating a plurality of vortexes in the fluid, the surface disturbances comprising a plurality of second inlets formed therein, in the second member; introducing the gas proximate to the plurality of vortexes in the first material through the plurality of second inlets in the second member, the plurality of second inlets being arranged in a pattern including at least two rows of spaced second inlets and located between the first inlet and the outlet thereby causing the fluid to flow past the plurality of second inlets, the plurality of vortexes diffusing the gas within the fluid; and causing the fluid with the gas diffused therein to exit the channel through the outlet.
