Abstract: An apparatus for effectively dissolving gas into liquid medium to obtain high concentration of gas solution comprises a mixer and a tank enclosure, wherein the mixer primarily comprises a quasi-Venturi tube and an expansion chamber. During operation, gas is introduced into the liquid in the quasi-Venturi-typed mixer.
