Pressure on surface waters is being increased due to human actions on land and new climate change scenarios. These new variables are causing impacts on water resources and sediment by watershed discharge or direct release of contaminants such as phosphorus and nitrogen, which are considered important factors for primary productivity. For this fundamental reason, eutrophication scenarios are augmented. In eutrophication occurrence, surface water will go through physical chemical and biological change including obnoxious smells, decrease of dissolved oxygen, and harmful toxin production. The market needs for remediation procedures to attenuate the presented issue are increasing as the occurrences of eutrophic water resources are growing every year. The eutrophication scenario attenuation is being addressed by the removal of suspended particles which are associated with nutrients using a floating filtration system, a silt curtain (i.e., for containment of a specific area), and geotextiles (woven and non-woven) as filter media. A novel, flexible, reactive and potentially economic environmental remediation is under development. Up to this date there is no similar treatment is being proposed in the specialized literature. By the geotextile filtration presented, removal of suspended solids and particulate phosphorus could be achieved reducing the likeability of eutrophication scenarios, improving the water resource quality and possibly decreasing/suppressing algal/cyanobacteria blooms. Therefore this Lab 2 Market application will assess the market for this technology to help prepare for the NSERC I2I Phase I proposal. Potential customers, their business model, and market entry point will be determined. These hypotheses are then validated through market research. The program is of four months in duration and is broken up into three distinct training phases. The Entrepreneurial Lead (EL) will be a full time PhD student who will work on the project full-time (20 to 40 hours/week) over the duration participating in all training sessions and all activities. By the end of the program, the appropriate path forward for the filtration project will be determined.

由于人类对陆地的活动和新的气候变化情景，地表水的压力正在增加。这些新变量通过流域排放或磷、氮等污染物的直接释放对水资源和沉积物造成影响，这些污染物被认为是初级生产力的重要因素。由于这个根本原因，富营养化的情况更加严重。富营养化发生时，地表水会发生物理化学和生物变化，包括恶臭、溶解氧减少、有害毒素产生等。随着富营养化水资源的出现每年都在增加，市场对缓解所出现问题的修复程序的需求也在增加。通过使用浮动过滤系统、淤泥幕（即用于限制特定区域）和土工织物（机织和无纺布）作为过滤介质去除与营养物相关的悬浮颗粒来解决富营养化情况的衰减。一种新颖、灵活、反应性且具有潜在经济性的环境修复方法正在开发中。迄今为止，专业文献中尚未提出类似的治疗方法。通过提出的土工织物过滤，可以实现悬浮固体和颗粒磷的去除，降低富营养化情景的可能性，改善水资源质量，并可能减少/抑制藻类/蓝藻水华。因此，此 Lab 2 市场应用程序将评估该技术的市场，以帮助为 NSERC I2I 第一阶段提案做好准备。 潜在客户、他们的商业模式和市场切入点将被确定。然后通过市场研究验证这些假设。 该计划为期四个月，分为三个不同的培训阶段。创业负责人 (EL) 将是一名全职博士生，他将在参与所有培训课程和所有活动期间全职（每周 20 至 40 小时）从事该项目。计划结束时，将确定过滤项目的适当前进路径。
