The supplied information lists 1 patent and identifies Suez International and Newport Corporation among the companies he worked in.

Latest Patents

Donnaz’s listed patent is titled “Method and Installation for Controlled Microbiome Shift for Biomass Densification in a Biological Treatment of a Raw Influent.” It describes a process that treats raw influent using free-suspended biomass, separates activated sludge to produce effluent and return activated sludge (RAS), and extracts waste activated sludge (WAS) from selected streams.

The method also uses density-based selection to separate biomass into an overflow and an underflow containing dense biomass aggregates. These aggregates, such as aerobic granular sludge or biofilm, are produced or sustained using at least part of the raw influent and then returned to the biological treatment process. The described steps aim to obtain densified biomass.

Career Highlights

The provided career information associates Donnaz with Suez International and Newport Corporation. His listed patent focuses on controlling biomass selection and aggregation in biological treatment, with the goal of supporting denser biomass in the treatment process.

Collaborations

The supplied information names Clément Roche and Sudhir N. Murthy as Donnaz’s coworkers. No specific roles or contributions to the listed patent are provided.

Conclusion

Sylvain Donnaz’s listed invention concerns controlled microbiome shifts and biomass densification for biological treatment of raw influent, reflecting a focus on process methods for managing biomass in treatment systems.
