GeoPro Talks - Electro-Coagulation for Groundwater Treatment
Webinar Wednesdays
Course Description
Now EC is seeing increasing use in another world entirely – the treatment of contaminated water including groundwater, landfill leachate, industrial wastewater, oily bilge water, greywater and blackwater from ships, municipal sewage, and household domestic greywater for reuse. Recently, Golder has started to apply this technology in the mining, solid waste and transportation sectors.
Recent research has shown the ability of EC to be modified to remove specific contaminants in the water – anodes made with magnesium, for example, have been shown to be successful in removing ammonia nitrogen during an EC-assisted struvite (a molecule made of equimolar concentration of orthophosphate, ammonium and magnesium) formation process. Also, major improvements have been made in recent years in anode and cathode cleaning methods in order to displace contaminants and debris from the anode and cathode surfaces, so that they retain their abilities to release cations, hydroxyl and hydrogen bubbles. EC can remove contaminants that are soluble as well as in suspension, and it works with a wide range of contaminants. That includes many contaminants that are difficult to remove by other methods, including cyanide, fluoride, sulfur and phenols. This makes EC a good solution particularly when there is a waste stream with many different contaminants, and where there is a need to treat the water with a single process.
Éric Bergeron
Mr. Éric Bergeron, Chemical Engineer, works as the leader of the water treatment group of the Golder Montréal Office. Mr. Bergeron has completed his undergraduate and postgraduate studies in Chemical Engineering at Sherbrooke University as process engineer. His thesis topic was the liquid waste plasma reforming. Before working for Golder, Mr. Bergeron has been in charge of the wastewater and air emission groups at Sodexen Inc. and more recently, Technical Director of Elite Technologies Inc. - Environmental division, a company specializing in instrumentation.Mr. Bergeron has over 25 years of professional experience in studies related to water treatment and soil remediation. As senior design process engineer, he has worked on several projects involving physical, biological and chemical process in-situ or ex-situ in Canada, USA, Australia and Europe.Mr. Bergeron was the design leader in the Nitchequon project, a chemical oxidation project performed in a remote site, a project that have won the Award of Excellence in the field of contaminated sites, at the 2008 Federal Contaminated Sites National Workshop. Mr. Bergeron was also the design leader for the Dow-Petromont remediation projects that has been named a winner by the Association of Engineers of Québec. Finally, Mr. Bergeron was the design leader for the bioremediation of a former tank farm, a project awarded for a Brownie Award in the category of Sustainable Remediation.
