Industrial Water Treatment
While the advantages of Electro Chemical Oxidation have been known and documented for many years, the technological barrier has been a material on the anode that has high overpotential and is commercially viable. Magneli Materials has developed coating technology that allows for Ti407 to coated on Anodes that are allow for Electro Chemical Advanced Oxidation systems to be created in the industrial waste water treatment industry.
Magneli’s engineering team began testing new Ti407 anodes in a new reactor configuration 2 years ago in our first pilot water treatment plant, a coke facility supplying the steel industry. In the past, anodes utilized in the oxidation wastewater treatment process could not withstand the high current densities, nor did they have the needed oxidizing power required in many hard COD situations. Our reactor design, anodes, and anode arrays performed above and beyond the current standards. Our engineers have evolved the anode technology continually over the last two years. Beginning with standard flat anodes with Ti407, advancing to mesh anodes with advanced catalysts coatings.
Two generations later, we have a state of the art reactive membrane anode as well as a new integrated reactor design, which can reduce operating expenses over previous technologies by 50% and decreased processing time for hard COD contaminant by 50%.
Our new Reactive Membrane technology incorporates a 3-dimensional ceramic Ti407 anode which has all the characteristics and performance of a Ti407 anode, but performs at a more advanced level due to a larger surface area than traditional anodes and the ability to allow for catalyst coats to be applied to support high current density operations. Standard Accelerated Life tests on the new Magneli Reactive Membranes have shown at 40,000 amps/m2 these anodes will last for over 110 hours, sulfate acid of 160 grams per liter.
