Preparation and testing of a sawdust-based phosphate filtration matrix

High concentrations of phosphate in the waterways cause algae blooms which are detrimental to water quality and fish habitat. The research project conducted by the Department of Chemistry & Biochemistry and the Upper Thames River Conservation authority, is attempting to alleviate this problem by chemically altering sawdust so that it can act as a phosphate filter thus removing excess amounts of phosphate. This filtration system is being tested with phosphate-rich wastewater produced from manure at a truck wash operation in the Upper Thames river basin.

Improving the reliability and accuracy of flood forecasting and warning systems

Hydrologic models, applied by engineers and hydrologists for flood forecasting and water budget modeling, are used to reproduce and predict the rainfall-runoff process to determine the response of the fluvial network (rivers, streams, etc.) to precipitation events. Changes in flow regime associated with precipitation events can result in flooding, drying up of stream flows, water quality degradation, loss of aquatic habitat, alterations to sediment transport processes, and damage to engineering infrastructure (e.g., bridge piers, drinking water intake pipes, water control structures, etc.).

Electrokinetic Dewatering of Orr Dam Sediment

This project involves a technical evaluation of the use of electrokinetic (EK) technology to dewater sediments that built up behind the Orr Dam in Stratford, to facilitate their removal and the continuation of normal Dam activities. EK dewatering involves the use of an applied electric field to a mass of soil in order to facilitate the removal of water from the soil. When an electric field is applied, the water is moved from the anode (positively charged electrode) to the cathode (negatively charged electrode).
