Abstract
A method and system for wastewater treatment includes flowing a quantity of a wastewater into a first microbubble chamber having a plurality of diffusers for injecting microbubbles into the wastewater to promote oxygenation. The microbubble includes activated sludge for treating the wastewater. The wastewater is then flowed from the first microbubble chamber through a plurality of rotating discs having a biofilm of microorganisms mounted thereon. The discs rotate about a shaft such that a portion of each disc is exposed to air during rotation. The wastewater is the flowed into a second microbubble chamber having a plurality of diffusers for injecting microbubbles into the wastewater. The treated wastewater is then recovered.
Claims12
A compact wastewater treatment plant comprising three or more bioreactors in series:
- a first microbubble/settling chamber having a settling chamber to collect suspended solids in communication with a microbubble chamber with a plurality of diffusers for injecting microbubbles into wastewater:
- a rotating biological contactor comprising a plurality of discs arranged for rotation about a shaft, said rotating biological contactor being in fluid connection with the first microbubble chamber;
- and
- a second microbubble/settling chamber having a settling chamber to collect suspended solids in communication with a microbubble chamber having a plurality of diffusers for injecting microbubbles in the wastewater, said second microbubble chamber being in fluid connection with the rotating biological contactor.
A method of treating wastewater comprising:
- flowing a quantity of a wastewater into a first microbubble/settling chamber, said microbubble/settling chamber having a settling chamber to collect suspended solids in communication with a microbubble chamber having a plurality of diffusers for injecting microbubbles into the wastewater, thereby promoting oxygenation of the wastewater;
- said microbubble/settling chamber further including activated sludge for treating the wastewater;
- flowing the wastewater form the first microbubble/settling chamber through a plurality of rotating discs, said discs having a biofilm of microorganisms mounted thereon;
- said discs rotating about a shaft such that a portion of each disc is exposed to aid during rotation;
- flowing the wastewater into a second microbubble/settling chamber, said microbubble/settling chamber having a settling chamber to collect suspended solids in communication with a microbubble chamber having a plurality of diffusers for injecting microbubbles into the wastewater;
- and
- recovering the treated wastewater.
