  • Method and installation for controlled microbiome shift for biomass densification in a biological treatment of a raw influent
    Patent number: 12729143
    Abstract: A method for controlled biomass densification in a biological treatment of a raw influent, includes a step of subjecting the raw influent to a biological treatment of free suspended biomass, thereby producing a biomass comprising activated sludge; a step of separation and/or clarification of the activated sludge, thereby producing an effluent and a RAS; a step of extracting at least part of the RAS and/or part of the activated sludge as a first source of a WAS; a step of external density-based selection of at least part of the RAS and/or part of the activated sludge, thereby generating an overflow intended to be extracted as a second source of WAS, and an underflow comprising dense biomass aggregates; a step of producing and/or sustaining dense biomass aggregates, such as aerobic granular sludge or biofilm, by a dense biomass aggregates generating process, with at least part of the raw influent; a step of subjecting the dense biomass aggregates to the biological treatment; a step of subjecting the dense bioma
