Abstract: An electrochemical cell design is disclosed for the particular application of the electrochemical treatment of contaminants in water. The cell is designed to allow the treatment of low concentrations of contaminants in low conductivity water efficiently, and to be simple to fabricate. The design incorporates tapered inlet and outlet fluid flow manifolds so that the cell pressure drop will be almost entirely due to fluid contacting the electrodes, thus maximising the effective use of the system pump power. A short anode to cathode distance and thin working electrodes are used to minimise resistive electrical power losses. The parallel slacked arrangement of the electrodes and the smooth inlet and outlet designs leads to relatively even distributions of current density and mass transfer resulting in maximal utilisation of the entire active electrode surface area.
