Biofilm plays an important role in water remediation, and are responsible for nutrient removal. Factors that affect the biofilm formation in such an environment include the influence of bacteriophage on their respective hosts. These factors can shape the microbial community in a wastewater treatment facility by playing roles in the formation of biofilm, be it in the form of floccular sludge or granules. While there has been intensive research into the identification and tracking of viruses that potentially infect humans or animals, relatively little work has focused on the effect of bacterial viruses and their impact on water reclamation plant (WRP) function. By developing a comprehensive understanding of the how bacteriophage can alter the physiological and ecological adaptations of microorganisms in the WRP, it may be possible to arrive at a better control of the biofilm communities in the sludge. Four independent sequencing batch reactors were established to address the links between bacteriophages and aerobic granulation with complex wastewater microbial communities. Single species studies are also done, allowing for better predictive models of how phage function in highly diverse communities.
