Abstract: This presentation focuses on some of the challenges faced in providing wastewater treatment in remote northern communities. Xogen Technologies, a startup company based in Orangeville is working towards the development of an electrochemical wastewater treatment process that occupies a small footprint and that can be integrated with renewable forms of energy. The challenges include designing electrodes which have an acceptable lifetime (corrosion is inhibited), have an activation potential that creates desirable electrochemistry at the electrode surfaces and is energy efficient, and designing a power source which is fault tolerant, has high availability, is modular and accounts for changes in the electrical conductivity of the wastewater.

The presentation begins with a review of the energy, environmental/geographical and wastewater issues in remote northern communities followed by a brief review of conventional wastewater treatment processes. The presentation will conclude with the research we are undertaking with Xogen Technologies towards developing an electrochemical treatment process.

Professor Lian in Materials Science is a cosupervisor on this project and Essam El Sahwi is the MaSc student who will be working on the power supply and the design of a controller for the electrochemical cell.
