Abstract
A method of biological treatment of materials by a combination of at least two groups of microorganisms forming sludges in at least two biological treatment zones treating the said materials wherein for purposes of increasing the treatment efficiency and stability at least one said sludges is conditioned in at least one sludge conditioning zone, whereby converting at least a fraction of at least one said group of organisms into organisms of another group, and thus forming the conditioned sludge, and the said conditioned sludge is fed in at least one said biological treatment zone.
Claims19
A method of biological treatment of materials by a combination of at least two groups of microorganisms forming sludges in at least two biological treatment zones treating the said materials wherein for purposes of increasing the treatment efficiency and stability
- at least one of the said sludges is conditioned in at least one sludge conditioning zone, whereby converting at least a fraction of at least one said group of organisms into organisms of another group, and thus forming the conditioned sludge, and
- the said conditioned sludge is fed in at least one said biological treatment zone.
A method of biological treatment of materials in at least two biological treatment zones selected from the group consisting of an anoxic biological treatment zone, an anaerobic biological treatment zone, an aerobic biological treatment zone, a facultatively anaerobic biological treatment zone, and combinations thereof, and further providing a conditioned sludge in at least one of the said at least two biological treatment zones.
