Membrane Filtration Development for Treatment of Shower Greywater in Real Time

加拿大人平均每天用水329升，洗澡和淋浴约占家庭用水的35%。这种水的再利用潜力很大，因为典型的淋浴水在进入废水处理系统之前只被轻度污染物（例如溶解的肥皂，身体油）轻微污染。水资源短缺促使人们需要从目前的取水-利用-处置水的线性经济模式转向处理-回收-再利用的新的再生循环模式。 Pledge Resource Managers Inc. dba RainStick Shower（RainStick）是一家位于安大略省的公司，开发灰水解决方案，能够捕获淋浴水的潜热能量。该公司的旗舰技术--闭环淋浴器（RainStick ShowerTM）可节省80%的水和能源消耗。该产品在每次淋浴后循环，处理，加热和重复使用灰水，帮助恢复一些从温水循环到下水道中损失的水和热量。RainStick希望克服与淋浴过滤技术相关的一些操作挑战，以便在北美实现RainStick淋浴的商业化。 该公司将与弗莱明学院的水和废水技术促进中心（CAWT）合作，在那里，该公司的技术将在受控条件下安装、运行、评估和优化。将特别注意膜过滤过程，确保过滤器始终如一地处理所需体积的水，而不会影响其寿命。该项目将提高RainStick的技术可信度，并将该技术商业化和营销。

The average Canadian uses 329 litres of water per day, with bathing and showering accounting for approximately 35% of water use in homes. There is a great potential for reusing this water, as typical shower water is only lightly soiled with mild pollutants (e.g. dissolved soaps, body oils) before entering a wastewater treatment system. Water scarcity is driving the need to move from the current linear economic model of take-make-use-dispose of water to a new regenerative circular model of treat-recycle-reuse. Pledge Resource Managers Inc. dba RainStick Shower (RainStick) is an Ontario-based company developing greywater solutions with the ability to capture the latent heat energy of shower water. The company's flagship technology, the closed-loop shower (RainStick ShowerTM), saves both water and energy consumption by 80%. The product recirculates, treats, heats, and reuses greywater after each shower, helping recover some of the water and heat that is lost from warm water cycling down the drain. RainStick is looking to overcome some of the operational challenges related to the shower's filtration technology, to allow for commercialization of the RainStick Shower within North America. The company will collaborate with Fleming College's Centre for Advancement of Water and Wastewater Technologies (CAWT), where its technology will be installed, operated, assessed and optimized under controlled conditions. Particular attention will be paid to the membrane filtration process, ensuring filters consistently treat the required volume of water without compromising their longevity. The project will lead to RainStick's increased technical credibility as well as commercialization and marketing of this technology.
