Abstract
In a water purification cell, a silver anode and a cathode have a spacing of 1 to 4 mm. The anode surface and the rate of water flow through the cell are related according to the equation F .gtoreq. c .times. V, wherein F is the anode surface area in cm.sup.2, V is the water flow rate in cm.sup.3 /second and c is a constant of the dimension sec/cm, with a value of 2 to 5. The density of the current in relation to the area of the anode surface is between 1.5 and 3.0 mA/cm.sup.2 and the voltage is such that active oxygen is generated at the anode.
