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大型营养素清除至非常低的水平，以避免接受水体的营养富集。目前，硝酸盐和磷酸盐主要通过廉价且具有高碳和能量足迹的生物学和化学过程从废水中除去。这项研究将使用新的生物膜检查一种吸附过程，以去除硝酸盐，磷酸盐以及从合成废水来源中的砷。这项研究将阐明这种新型生物膜的应用和相关的设计需求领域。因此，如果被证明可以有效地从废水中清除这些养分，则它将为加拿大市政当局和废水提供替代方案。
