There exist few technologies worldwide for the treatment of large areas of polluted salt and fresh water. The approach under development in partnership with Titan Environmental Containment is for the treatment of surface water for the removal of nutrients such as phosphorus, cyanobacteria, algae and other components that cause undesirable characteristics such as colour or odor. The long-term objective is thus to develop as system for the restoration, management and control of water quality in situ. The short-term objectives are:**- To determine the parameters that influence the nutrient removal efficiency**- To determine the mechanisms of treatment**- To determine the factor for scale-up**- To investigate the relationship between sediment and water quality.**The project is scheduled for two years. The first years will involve sampling of water and sediment quality at two different lakes (Lac Caron and Lac Johanne) in the Sainte-Anne-des-Lacs region, of the Laurentians, Quebec. Geotextiles will be used as the filter materials based on laboratory and on-site testing. The testing at Lac Caron ( a lake with the lowest quality in the region where swimming is banned) will begin once the levels of phosphorus increase to above acceptable levels. A small unit will be placed in a isolated section in the lake to evaluate its ability to removed suspended solids, phosphorus, chlorophyll, bacteria and other parameters in the first and second years over various seasons. Water treatment efficiency and parameters for scale-up will be determined. At Lac Johanne, some preliminary tests will be done in the first year to determine the filter`s ability to remove organic matter that caused a brown colour. The second year will involve more extensive in situ testing. The sediment quality will also be monitored during the in situ tests as it will have an influence on the water quality. The protection and improvement of the water quality by nutrient reduction will improve the aesthetics of the water, health of the community and allow the water to be used for recreational purposes and increase property values. ****

全世界很少有技术可以治疗大片污染的盐和淡水。与泰坦环境遏制合作开发的方法是用于处理地表水，以去除磷，蓝细菌，藻类和其他引起不良特征（例如颜色或气味）的养分。 因此，长期目标是发展为原位恢复，管理和控制水质的系统。短期目标是：** - 确定影响养分去除效率的参数** - 确定治疗机制** - 确定扩展因素**的因素** - 研究沉积物与沉积物之间的关系水质。**该项目计划进行两年。第一年将涉及在魁北克劳伦斯人的Sainte-Anne-Des-Lacs地区的两个不同湖泊（Lac Caron和Lac Johanne）的水和沉积物质量进行抽样。基于实验室和现场测试，土工布被用作过滤材料。 一旦磷的水平增加到可接受的水平，将开始在LAC Caron（禁止游泳的地区质量最低的湖泊）进行测试。 一个小单元将在湖中的一个孤立区中放置，以评估其在各个季节的第一年和第二年中去除悬浮固体，磷，叶绿素，细菌和其他参数的能力。将确定水处理效率和用于扩大的参数。在Lac Johanne，将在第一年进行一些初步测试，以确定过滤器去除导致棕色的有机物的能力。第二年将涉及更广泛的现场测试。在原位测试期间，还将监视沉积物质量，因为它会对水质产生影响。通过减少营养的保护和改善水质将改善水的美学，社区的健康，并允许水用于娱乐目的并增加财产价值。 ****
