Abstract
Systems and methods for aerobically processing waste, in which an aerobic bioreactor is in selective fluid communication with a source of oxygen-rich liquid medium. The aerobic bioreactor is configured for aerobically processing waste via bacteria fixed on media to provide processed effluent from the waste. The source of oxygen-rich liquid medium is different from the aerobic bioreactor.
Claims19
A system for aerobically processing waste, comprising:
- an aerobic bioreactor configured for aerobically processing waste via bacteria fixed on media to provide processed effluent from the waste;
- a source of oxygen-rich liquid medium, comprising photosynthetic microorganisms that generate oxygen in said liquid medium responsive to exposure to light, said source being different from said aerobic bioreactor, said source being in selective fluid communication with said aerobic bioreactor;
- wherein said media is mobile within the bioreactor.
A method for aerobically processing waste, comprising:
- reacting waste aerobically with bacteria in a bioreactor volume under conditions configured for inhibiting or reducing growth of photosynthetic microorganisms, wherein said bacteria are fixed on media, and said media is mobile within the bioreactor volume;
- providing a flow of oxygen-producing photosynthetic microorganisms through the bioreactor volume from a source configured for promoting oxygen production by photosynthetic microorganisms, the source being different from the bioreactor volume, the photosynthetic microorganisms generating and providing oxygen to said liquid medium responsive to exposure to light;
- exposing said photosynthetic microorganisms to light in said source prior to said photosynthetic microorganisms being caused to flow through the bioreactor volume, to thereby generate and provide said oxygen to said liquid medium;
- and
- preventing at least a majority of the bacteria from exiting the bioreactor with said flow of photosynthetic microorganisms.

A system for aerobically processing waste, comprising:
- an aerobic bioreactor configured for aerobically processing waste to provide processed effluent from the waste using bacteria being fixed on media;
- a source of oxygen-rich liquid medium, said source being different from the bioreactor, said liquid medium comprising photosynthetic microorganisms that generate oxygen in said liquid medium responsive to exposure to light;
- a recirculation circuit configured for controllably recirculating said liquid medium between said aerobic bioreactor and said source;
- wherein said media is mobile within the bioreactor.
