Simultaneous Removal of Ammonia, Urea, and Metals From Water

Overview

Ammonia, urea, and metals are all species that are commonly presented in wastewater that is derived from different sources. There are different processes that facilitate the removal of these species individually, including ion exchange, reverse osmosis, electro-winning, etc. However, none of these processes possess the ability to remove all of these species simultaneously. Such simultaneous removal can be achieved through oxidation by electrocatalysts and other additives. The method includes applying a voltage to an electrolytic cell that compromises an anode, a cathode and an alkaline electrolyte composition having a pH value of 11 or less.
