Arsenic and fluoride removal by electrocoagulation process

Jan 20, 2021 Arsenic/fluoride removal efficiency has been observed to decrease when there is i) a larger distance between the electrodes, which results in a growing passive layer and poor mass transfer affecting the production rate of the coagulating agents and ii) a narrower interelectrode gap, which results in the accumulation of gas bubbles, increasing the electrolyte resistance and flocs damage due to excessive collisions
