Abstract

The disclosed device is directed toward a rotary water treatment system comprising at least one open channel cell configured to contain a liquid. A cylinder partially disposed in the open channel cell. The cylinder having a first end and a second end opposite the first end, and a cylinder wall coupled between the first end and the second end. The cylinder wall including a plurality of perforations formed in the cylinder wall. A motive force element is coupled to the cylinder configured to impart rotary motion to the cylinder. At least one influent supply is coupled to the at least one open cell. At least one effluent discharge is coupled to the at least one open cell. A pump is fluidly coupled to the at least one influent supply.

A treatment system comprising:

a first container comprising a first end and a second end opposite said first end, a first container wall disposed between said first end and said second end, said first end, said container wall and said second end defining a first interior and a first exterior, said first end, said container wall and said second end defining a first container opening;
a second container fluidly coupled to said first container, said second container comprising a first end and a second end opposite said first end, a second container wall disposed between said first end and said second end, said first end, said container wall and said second end defining a second interior and a second exterior, said first end, said container wall and said second end defining a second container opening;
a first aerator partially disposed in said first interior through said first container opening, said first aerator comprising a body having a first end and a second end opposite said first end, said body comprising an aerator wall disposed between said first end and said second end, said aerator wall including a plurality of perforations through said aerator wall, said first end, said second end and said aerator wall defining a first aerator interior and a first aerator exterior, said first aerator configured to partially rotatably dispose in a liquid contained in said interior of said first container, said first aerator configured to aerate said liquid both at said first aerator interior and said first aerator exterior, wherein said plurality of perforations formed in the first aerator wall are configured to lift a thin film of said liquid from said first container by exploiting the surface tension of said liquid, wherein said thin film bridges said plurality of perforations, and said first aerator is configured to create a cascading bubbling turbulent flow in said liquid flowing along said first aerator wall, as well as said liquid contained in said first container;
a second aerator partially disposed in said second interior through said second container opening, said second aerator comprising a body having a first end and a second end opposite said first end, said body comprising an aerator wall disposed between said first end and said second end, said aerator wall including a plurality of perforations through said aerator wall, said first end, said second end and said aerator wall defining a second aerator interior and a second aerator exterior, said second aerator configured to partially rotatably dispose in a liquid contained in said interior of said second container, said second aerator configured to aerate said liquid both at said second aerator interior and said second aerator exterior, wherein said plurality of perforations formed in the second aerator wall are configured to lift a thin film of said liquid from said second container by exploiting the surface tension of said liquid, wherein said thin film bridges said plurality of perforations, and said second aerator is configured to create a cascading bubbling turbulent flow in said liquid flowing along said second aerator wall, as well as said liquid contained in said second container;
and
a rotary motive force element operatively coupled to said first aerator and said second aerator, said rotary motive force element configured to rotate said first aerator and said second aerator.
