A water treatment system is disclosed having an electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite or potable water to be oxidized. The cell has first and second opposing electrode end plates held apart from each other by a pair of supports such that the supports enclose opposing sides of the end plates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.

A microchannel-membrane device comprises a microchannel extending through at least one electrode, the microchannel having a predetermined depth; an ionic permselective medium, such as a membrane, across the microchannel between the electrodes; and a heater, or array of heaters, embedded below the microchannel on at least one side of the permselective membrane. The heaters can be either prefabricated or dynamically patterned using laser illumination with/without photoconductive coating. The heaters are on the depletion side of the membrane and induce a vortex which limits the growth of the diffusion area. Operation of the heaters allows for controlled positioning of the end of the diffusion area and with it also the position of the preconcentrated molecule plug.
