Phosphorus recovery from wastewaters and its recycling are of importance for sustaining agricultural production. During the conventional enhanced biological phosphorus removal process, phosphorus is removed by withdrawing excess sludge from wastewater. However, excess sludge disposal is costly and energy intensive. A proposed novel process for phosphorus(More)
Biogenic manganese oxides (bio-MnO₂) have been shown to absorb minor metals. Bioreactor cultivation of heterotrophic manganese oxidizing bacteria (MnOB), which produce bio-MnO₂ via oxidation of Mn (II), can be expected to be involved in a promising system for removal and recovery of minor metals from wastewater. However, MnOB enrichment in wastewater(More)
Candidatus Accumulibacter phosphatis (Accumulibacter), which plays an important role in enhanced biological phosphorus removal in wastewater treatment plants, is phylogenetically classified into two major types (Types I and II). Phosphate concentrations affect the Accumulibacter community of the biomass enriched in treatment plants. Therefore, in the(More)
