Abstract

This doctoral thesis developed and investigated BauxsolTMpellets for the bio-geochemical treatment of municipal wastewater. Field experiments demonstrated the effectiveness of BauxsolTM pellets to bind phosphate (~95% removal over 6 months) and trace-metals from wastewater. Moreover, genetic analysis confirmed the biocompatibility of BauxsolTM pellets in wastewater treatment. These results showed distinct, well-adapted, and highly diverse microbial communities attached to BauxsolTM pellet. Many of the bacterial communities investigated were involved in the nitrogen cycle, which is ~50% bio-geochemically removed. In conclusion, BauxsolTM pellets provided an improved treatment to municipal wastewater by promoting biological processes while eliminating chemical use for phosphate precipitation.
