加拿大现有的城市污水处理厂（WWTP）可能面临挑战，以应对新的污水排放 CCME下的总悬浮物（TSS）和生物需氧量（BOD）排放法规 加拿大城市废水排放管理全战略法规。废水处理设施 在未来几年，我们将寻找替代技术，以满足更严格的国家水质要求 污水处理排放标准。采用膜技术处理污水二级出水 城市污水处理厂仍然是需要三级处理的系统的新兴领域 用于饮用水和非饮用水再利用应用。低压膜的使用，特别是 超滤（UF）模块可以提供替代的、成本有效的方法来实现上级水质 经处理的废水，可以满足新的国家排放标准，而无需进行重大系统升级， 重新设计现有系统。超滤膜可以为小至 0.01微米，这将实现目标成分的有效去除，许多目前的主要或 二级污水处理厂的设计不能始终如一地实现。这项为期6个月的研究项目将有利于市政 污水处理部门的调查，在试点规模的有效性，使用膜技术， 二级出水，并确定可以达到的排放水质。研究结果将 提供新的信息，可用于废水处理行业，以实现目标水质，以满足 新的排放标准和/或系统正在设计/修改用于水回收应用。

Existing municipal wastewater treatment plants (WWTP) in Canada may face challenges meeting new effluent discharge regulations for total suspended solids (TSS) and biological oxygen demand (BOD) under the CCME Canada Wide Strategy for the Management of Municipal Wastewater Effluent regulations. Wastewater utilities will be looking for alternative technologies in the coming years to meet more stringent national water quality standards for sewage treatment effluents. The use of membrane technology to treat secondary effluent from municipal wastewater treatment plants continues is an emerging field for systems that require tertiary treatment for potable and non-potable water reuse applications. The use of low-pressure membranes, specifically ultrafiltration (UF) modules may offer an alternative, cost effective approach to achieve superior water quality on treated effluents that can meet the new national discharge standards without major system upgrades or redesign of existing systems. UF membranes can provide an absolute barrier to particulate material as small as 0.01 µm which would achieve efficient removal of the target constituents that many current primary or secondary WWTP designs cannot consistently achieve. This 6-month research project will benefit municipal wastewater treatment sector by investigating at pilot-scale the effectiveness of using membrane technology on secondary effluent and determining the discharge water quality that can be achieved. Results of the study will provide new information that can be used by the wastewater industry to achieve target water qualities to meet new discharge standards and/or systems that are being designed/modified for water reclamation applications.
