A dissolved carbon air flotation has a CO2 bubbler for separating large particles from small particles by flotation. An anaerobic digester produces biogas. The digester has a biocurtain for growing the bacteria and a heat exchanger for heating the bacteria. The biocurtain surface is convoluted to retain the bacteria. A membrane module removes CO2. A knock out pot for removes droplets of water. A scrubber removes water vapor, particulates, and contaminant gas. A compressor boosts pressure. A gas chromatograph monitors the biogas composition. A flare skid lowers excess pressure for safety. Biogas is injected into a local pipeline system.

Abstract: Large sealed anaerobic digestor ponds with thin rubber membrane covers to absorb sunlight efficiently in selective sunlight absorption coating and low emissivity in infrared and transparent insulation layers. Flow of pond byproduct gas and heat transfer to circulate slurry liquid controlled by pressurization and weighting of gas collection cover membrane to provide sloped buoyant bubble gas flow gas collection channels in deformed membrane. Low gas pressure used between layers to increase heat transfer to digesting slurry when low wind and prevent wind lift-off with high winds. High gas pressure used between membrane layers to remove sloped collection channels, permit thickened foam over digesting slurry and reduce heat transfer at night. These large-scale solar heating digesting ponds can maintain sufficient digestion temperature to accelerate digestion, maximize gas production efficiency, and minimize greenhouse gas emissions.
