On the THM Formation during Inline Electrolysis – First Systematic Laboratory-Scale Studies

On the THM Formation during Inline Electrolysis – First Systematic Laboratory-Scale Studies

Formation of THM species was studied using parallel plate cells and water systems typical for drinking water composition. Current density was varied between 50 A m-2 and 200 A m-2 at room temperature on mixed oxide electrode material as used under practical conditions. Partially, at higher specific...
