Open the CIPO recordAbstract From the Canadian patent
The invention disclosure is a method of bioremediation of wastewater particularly groundwater, by utilizing coupled anaerobic and aerobic biological treatment, more specifically methanogenic (strictly anaerobic) and methanotrophic (strictly aerobic) microbial populations in combination with a , supply of in-situ generated water-dissolved oxygen and hydrogen. Water electrolysis is used to produce water-dissolved oxygen and hydrogen. The immediate advantage of using H2 from the electrolysis is to provide electron , donors to methanogens to reductively dechlorinate the chloroaliphatics and to , reduce the water carbonates and generate methane which is used as energy and carbon source for …
