Electrocoagulation
Process Principles: Electrocoagulation
Electrocoagulation is a water treatment process whereby an electric current is applied across metal plates to remove various contaminants from water. Heavy metals (ions) and colloids (organics and inorganics) are primarily held in solution by electrical charges and particle size. By applying an electrical charge to a solution of contaminated water, you can destabilize the charges on the various particles and generate a coagulation reaction.
The WaveIonics System
WaterTectonics has been designing, manufacturing, and deploying high-flow, packaged electrocoagulation systems since 1999. From the start, our primary goal as a company was to build the best electrocoagulation system in the world. After 10 years of research and development, we built our first full-scale system. Over the next 13 years, we put our technology to work in full-scale operation at some of the dirtiest, most challenging sites we could find - from contaminated construction sites to scrap metal processing yards to natural gas drilling pads. Our broad exposure to multiple applications and continued commitment to improvement has made our WaveIonics technology higher performance, more robust, and more reliable.
Technology Specifications
- All systems are pre-engineered and can be delivered packaged, weatherized, and mobile
- Scalable design includes 100gpm systems packaged in 10' containers all the way up to 15,000+ gpm packaged plant systems
- Non-selective treatment is broadly effective and largely independent of contaminant species, concentrations, and competing properties
- Extensive automation controls with web-based remote monitoring and alert systems significantly reduce operational maintenance and labor
- All systems are UL rated; intrinsically safe Class 1, Div 2 systems are available
- Subtractive process does not require any chemical reagents or polymers; typically produces 30-70% less sludge than conventional chemical processes
- Approved as a General Use Level Designation (GULD) technology by the Washington State Department of Ecology (Click here to view)
- Third-party verified safe for chronic and acute toxicity; no risk of over-dosing as with chemical treatment
