KLa jet aerators transfer oxygen by simultaneously introducing large volumes of high kinetic energy liquid and air through a series of jet nozzles. The high velocity liquid exits the inner, primary jet and rapidly mixes with the in-coming air in the outer jet. The intense mixing and high degree of turbulence rapidly dissolves the air into a fine dispersion of gas and liquid. This high velocity, oxygen rich cloud is discharged from the outer nozzle where the plume mixes with and entrains the surrounding liquid. Each individual jet plume travels horizontally along the basin floor prior to the vertical rise of the gas bubble column to the surface.
