项目摘要

Biofiltration for drinking water treatment is undergoing a paradigm shift that is taking it from a passive process to an engineered process. Engineered biofiltration is an emerging technology focused on the purposeful operation of biofilters to achieve conditions that are beneficial to bioactivity and the subsequent biodegradation of contaminants. Biofiltration can shift some of the burden of contaminant removal from chemically-driven processes to a biodegradation process, resulting in chemical and cost savings that can improve the sustainability of the overall drinking water treatment process. ******Despite reliance on biofilms to provide contaminant biodegradation, the functional potential of microbial communities present in drinking water biofilters is still largely unknown. Therefore, the overarching objective of this research program is to provide new insights into the functional potential of the microbial communities present in drinking water biofilters. Specific themes of this research program include identifying novel parameters that have potential to rapidly indicate the overall bioactivity and viability of the biofilter microbiome, exploring the underlying microbial community structure associated with bioactivity outcomes and developing treatment technologies that support active and functional core microbiomes. ******This research program will train an estimated eight highly qualified personnel over a five-year period. The overall research program will strive to advance biofiltration knowledge to support sustainable water treatment. It is anticipated that findings from this research program will support drinking water treatment innovation by contributing to the understanding of the metabolic and phylogenetic conditions present in biofilters.

饮用水处理的生物过滤正在经历范式转移，该范式将其从被动过程转变为工程过程。工程生物过滤是一种新兴技术，侧重于生物过滤器的有目的运行，以达到有益于生物活性和随后的污染物生物降解的条件。生物过滤可以将污染物去除的某些负担从化学驱动的过程转移到生物降解过程，从而获得化学和成本节省，从而可以改善整体饮用水处理过程的可持续性。 ******尽管依靠生物膜提供污染物生物降解，但饮用水生物过滤器中存在的微生物群落的功能潜力仍然很大程度上是未知的。因此，该研究计划的总体目标是为饮用水生物过滤器中存在的微生物群落的功能潜力提供新的见解。该研究计划的特定主题包括识别具有快速表明生物滤器微生物组的总体生物活性和生存能力的新参数，探讨了与生物活性结果相关的潜在微生物群落结构，并开发了支持主动和功能性核心微生物组的治疗技术。 *****该研究计划将在五年内培训估计的八名高素质人员。整个研究计划将努力提高生物过滤知识，以支持可持续的水处理。可以预料，该研究计划的发现将通过理解生物过滤器中存在的代谢和系统发育状况来支持饮用水的创新。
