E2Metrix has developed an advanced electro-coagulation process for the reduction and recovery of nutrients in wastewater. The ECOTHORTM process uses a unique, magnesium-alloy, sacrificial electrode and advanced power management to remove phosphorus down to <0.01 mg/l and recover struvite, and to also remove suspended solids, FOG (fats, oil and grease) and other micro-contaminants. Full-scale installations are already in operation at food processing facilities, landfill leachate sites, mines (ammonia reduction in contaminated groundwater at a Quebec gold mine) and on sanitary wastewater. The technology has been developed as a modular, Plug ‘n Play tertiary filtration solution that may be incorporated easily into any green field or retrofit application, from <20 to >4,000 m3/d. In joining ESPP, which provides a forum for sustainable phosphorus information transfer, E2Metrix is eager to share its experience in the use of electro-coagulation as a mechanism for effective phosphorus removal and recovery, particularly for smaller municipal and industrial applications where alternative processes may not be practically or economically feasible.
