A majority of wastewater treatment plants in Canada are required to remove macronutrients like phosphate andnitrate to very low levels to avoid nutrient enrichment of receiving water bodies. Currently nitrate andphosphate are primarily removed from wastewater through biological and chemical processes which areexpensive and have a high carbon and energy footprint. This research will examine an adsorption process usinga novel biomedia for removal of nitrates, phosphates, as well as arsenic from a synthetic wastewater source.This research will clarify the areas of application and associated design needs with this novel biomedia. Thus,if the biomedia is proven to effectively remove these nutrients from wastewater, it will offer an alternativefinancially and environmentally beneficial technology to Canadian municipalities and wastewater utilities.

加拿大的大多数废水处理厂都需要将磷酸盐和硝酸盐等常量营养素去除到非常低的水平，以避免接收水体的营养富集。目前，硝酸盐和磷酸盐主要通过生物和化学过程从废水中去除，这些过程成本高，碳足迹和能源足迹高.本研究将探讨一种新型生物介质吸附法去除合成废水中的硝酸盐、磷酸盐和砷，并阐明这种新型生物介质的应用领域和相关设计需求。因此，如果生物介质被证明可以有效地从废水中去除这些营养物质，它将为加拿大市政当局和废水公用事业提供一种替代的经济和环境有益的技术。
