filtration systems at a variety of project sites managed by Dillon Consulting. Dillon Consulting Ltd. approached_x000D_
us to understand the causes and provide potential remedies to such clogging issues. Precipitants will be_x000D_
collected and analyzed for iron, calcium, sulfur, carbonate, magnesium, phosphorus, nitrogen, organic carbon,_x000D_
protein, potassium, and sodium to determine the composition of the clogging agents. Analysis of physical and_x000D_
chemical conditions occurring upstream of the precipitation problems will be conducted to determine combined_x000D_
effects of ion concentration, water flow rate, temperature and pH on precipitation. Process design alterations_x000D_
and flow configurations to mitigate precipitate formation and accumulation will be determined. Of particular_x000D_
interest is precipitation occurrence in conditions of low ion concentration and what changes can be made to_x000D_
avoid these problems. Test columns of filter media of different porosity and character (e.g. sand and inert_x000D_
recycled glass as control) will be evaluated to determine optimum percolation rates to avoid clogging. Through_x000D_
another research project, a site is available to us in the Village of Dunnottar, MB for pilot scale testing of_x000D_
precipitate forming conditions as well as remediation options. Dillon Consulting will benefit from this study, as_x000D_
they will better understand operational challenges associated with inorganic precipitation and consider design_x000D_
changes to existing and future sites., program purpose french : In this research project, we will survey clogging problems currently experienced in wastewater sub-surface_x000D_
