Also yes, the improved aeration from the new blowers resulted in energy savings from other parts of the treatment process, not the biogas part.

Its a very old technology not a “new sustainable energy technology for the future” there are millions of plant in operation around the world mainly at homestead but also at industrial level and originates in the 19 century if I remember correctly. Since its so effective lets hope it does become a technology of the future.

Biogas is produced by the anaerobic (without air) fermentation of organic waste, so the aeration definitely doesn’t make the biogas process run faster. I assume it improves other parts of the process which improve the integration between sewage treatment and biogas production.
