At least one of an anode and a cathode or at least a cathode has holes or pores for filtration. To remove floating material, soil suspending materials and/or hydroxides such as Calcium formed on the filterable electrode(s), at intervals between the electrolysis processes, the direction of water flow is reversed, and treated water is pulled back through the electrode(s) and electrolyzed again, whereby the materials deposited on electrode(s) is removed.
