Claims17
A mixing- and aeration unit comprising:
- a submersible axial flow mixer, a number of air bubble diffusers and an air feeding compressor, wherein a mixer is connected to an elongated jet ring, an inlet of the jet ring being adjacent a mixer propeller and that the air bubble diffusers are positioned within the jet ring, wherein each of said air bubble diffusers comprises a tubular member, and each of said tubular members is positioned substantially parallel to a central axis of said jet ring.
A mixing- and aeration unit comprising:
- an elongated jet ring having an longitudinal axis and including an inlet;
- a mixer including a mixer propellor and connected to said elongated jet ring such that said mixer propellor is positioned within said jet ring, adjacent to said inlet, and adjustable between different positions relative said inlet;
- and,
- a plurality of tubular shaped air bubble diffusers positioned in said jet ring in a manner substantially parallel to said longitudinal axis of said jet ring.
