Reference number : GC-2017-Q4-01315, amendment number : , agreement type : G, recipient legal name : Mulligan, Catherine (Concordia University)|Mulligan, Catherine (Université Concordia), recipient country : CA, recipient province : nan, recipient city : Quebec|Québec, recipient postal code : nan, program name english : Engage Grants for universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : Nutrients enter into lakes through point and non-point sources are finally settled in bottom sediments where_x000D_
they accumulate and eventually release back into the overlaying water. Sediment phosphorus release is one of_x000D_
the main reasons for eutrophication in many shallow lakes around the world. This present study examines_x000D_
sediment samples collected from Lake Caron, a eutrophic lake to understand the potential removal of_x000D_
phosphorus from the sediment using a resuspension technique coupled with filtration. The average P_x000D_
concentrations in the Lake Caron sediments ranged between 908 and1310 mg/kg P. Depending on the chemical_x000D_
forms of P in the sediments, significant sediment P release was observed at both acidic and alkaline conditions_x000D_
and thus could have a significant influence on lake water quality. It is proposed to develop a filtration_x000D_
technology with geotextile technology with Texel for the removal of organic matter, algae and nutrients. The_x000D_
system will done in the laboratory and will consist of a tank, tubing and aeration for suspension of sediments, a_x000D_
pump for removal of the suspended material and a filtration apparatus for removal of the water from the_x000D_
suspended matter. Trials in the laboratory will begin early spring using various samples of phosphorus_x000D_
containing sediments taken in 2017. Nonwoven geotextiles (Texel) will be used as the filter materials for_x000D_
suspended matter from resuspension of sediments. Various pore size geotextiles will be evaluated to determine_x000D_
the optimal for removal of nutrient based resuspended sediment. As the ice melts, fresh surface sediment_x000D_
samples will be obtained from Lac Caron. Filtration tests will determine removal of organic matter, SS,_x000D_
nutrients from the sediments. Development of the filtration module will significantly expand the applicability_x000D_
of the geotextiles for sediment treatment to reduce occurrence of blooms due to high nutrient levels. Various_x000D_
geotextiles will be evaluated. The protection and improvement of the water quality by nutrient reduction will_x000D_
improve the aesthetics of the water, health of the community and allow the water to be used for recreational_x000D_
purposes and will ensure the protection of the property values., program purpose french : Nutrients enter into lakes through point and non-point sources are finally settled in bottom sediments where_x000D_
