Sanford is calling on two state agencies to say what they know regarding the 1,4-dioxane contamination first discovered a decade ago in the city’s wells, including at what concentration and over ...
Electro-oxidation (EO or EOx), also known as anodic oxidation or electrochemical oxidation (EC), is a technique used for wastewater treatment, mainly for industrial effluents, and is a type of advanced oxidation process (AOP). [1] The most general layout comprises two electrodes, operating as anode and cathode, connected to a power source.
