Patent ID: 8110108

Claim:
A method of treating wastewater; the method comprising: deploying a plurality of floating wastewater treatment devices within a wastewater containment reservoir containing a body of wastewater, each of the plurality of floating wastewater treatment devices having an input region and an output region, each of said plurality of floating wastewater treatment devices comprising: a microorganism clad structure at least partially submerged in the body of wastewater paired with an upstream aeration device which provides; a source of a rapidly flowing wastewater stream directed generally toward the microorganism clad structure; and an apparatus adapted to introduce into the rapidly flowing wastewater stream a concentration of at least one atmospheric gas which is enhanced relative to the concentration of that atmospheric gas within the wastewater adjacent to the rapidly flowing wastewater stream at the point at which the stream is introduced into the body of wastewater, wherein the output regions of at least some of the plurality of floating wastewater treatment devices are adjacent the input region of a separate floating wastewater treatment device; introducing a first quantity of wastewater into the input region of a first floating wastewater treatment device; conveying at least some of the output of the first floating wastewater treatment device to the adjacent input of a succession of at least one floating wastewater treatment devices; and conveying at least some of the output of the last of the floating wastewater treatment devices out of the water containment reservoir containing a body of wastewater.
