Claim:
1. A method of controlled aeration of a liquid comprising the steps of: obtaining an apparatus comprising a dome supported by a flotation device, a lower housing supported by said flotation device, said lower housing connected to said dome, wherein a sealed space is defined under said dome and above the liquid; a blower, said blower disposed in a position enabling an effect therefrom on a pressure in said sealed space, one or more orifice in said dome, each orifice further comprises a dampening device configured to adjust the air flow through said orifice from said blower, an aeration apparatus positioned within said sealed space and partially submerged in the liquid, wherein said aeration apparatus comprises one or more parallel shafts, at least one first disc positioned axially on one of said shafts, at least one second disc positioned axially on another of said shafts, wherein said second disc is interleaved relative to said first disc, and wherein said first disc rotates in a direction opposite said second disc relative to each other resulting in a mixing area therebetween, and at least two strakes, wherein a first strake is carried by said first disc and a second strake is carried by said second disc; striking said first strake with the liquid to release gas from the liquid, and wherein said blower ventilates the gas via said orifice from said dome; trapping the liquid between said first disc and said second disc in a mixing area; forcing a gas depleted liquid up into said mixing area by said first strake; forcing a gas within said dome down into said mixing area by said second strake; and creating a shear force between the gas and said gas depleted liquid therein said mixing area to increase a dissolved gas in the liquid.
