High-efficiency airlift pump

An airlift pump comprising:

• an injection port for injecting pressurized air into the airlift pump;
• a mixing chamber;
• and
• a device positioned in use between an injection port and a mixing chamber within an airlift pump, wherein the device comprises a planar body with multiple holes extending therethrough, the multiple holes dimensioned to direct gas into multiple micro-streams for streaming the gas from the injection port into the mixing chamber, wherein the multiple holes have diameters between 0.15 mm and 0.25 mm.

An airlift pump comprising:

• an injection port for injecting pressurized air into the airlift pump;
• a mixing chamber with perforations, the mixing chamber coupled to the injection port for receiving air from the injection port and receiving water through the perforations;
• a lift tube fluidly connected to and extending from the mixing chamber;
• an ejection port fluidly connected to and extending from the lift tube, the ejection port comprises a gas discharge aperture and a liquid discharge aperture;
• and
• a gas streaming device positioned between the injection port and the mixing chamber, the gas streaming device comprises a planar body with multiple holes extending therethrough, the holes dimensioned to direct the gas into multiple micro-streams for streaming air from the injection port into the mixing chamber.
