Abstract
Provided herein are methods and systems for treating a stream comprising material (e.g., biomass such as plant biomass, animal biomass, agricultural biomass, wastewater sludge, or a combination thereof) with nanobubbles. One such method includes generating nanobubbles in wastewater sludge of a wastewater treatment system to produce nanobubble-containing sludge, the wastewater sludge having a higher solids content than an input stream to the wastewater treatment system, and processing the nanobubble-containing sludge in an anaerobic reactor of the wastewater treatment system.
Claims13
A method comprising:
- generating nanobubbles directly in a stream of a system to produce a nanobubble-containing stream using at least one nanobubble generator, wherein the stream has a solid concentration of at least 1,200 mg/L;
- introducing the nanobubble-containing stream to an anaerobic reactor of the system;
- and
- anaerobically processing the nanobubble-containing stream in an anaerobic reactor of the system.
A method comprising:
- generating nanobubbles directly in a stream of a system to produce a nanobubble-containing stream using at least one nanobubble generator, wherein the stream has a chemical oxygen demand of at least 2,000 mg/L and/or the stream has a biological oxygen demand of at least 1,000 mg/L;
- introducing the nanobubble-containing stream to an anaerobic reactor of the system;
- and
- anaerobically processing the nanobubble-containing stream in an anaerobic reactor of the system.
