Abstract:

An improved electrolytic cell, its method and system is disclosed. The electrolytic cell () is configured, at least in one design, to recycle the catholyte to increase chlorine capture and concentration in the output solution. The cell () includes at least an anode chamber () and a cathode chamber (). And in one design, a chamber or reservoir () for that serves as a source of anions and cations for the anode and cathode chambers. The outlet () of the cathode chamber is preferably connected in fluid communication with the inlet () of a degassing chamber () and the outlet () of the degassing chamber is preferably connected in fluid communication with the inlet () of the anode chamber.
