A micro-reactor system for contacting fluids is described. The system comprises a first microfluidic channel structure for guiding a first fluid to at least one output nozzle thus generating a first sub-flow, a second microfluidic channel structure for guiding a second fluid to at least a second output nozzle thus generating a second sub-flow, said first output nozzle being aligned with said second output nozzle and arranged for contacting the first sub-flow and the second sub-flow. The micro-reactor comprises at least a third microfluidic channel structure for at least a third, inert, fluid generating at least a third sub-flow arranged to be positioned adjacent at least the first and/or the second sub-flows so as to act as a wall between said first and/or second sub-flows.

A water treatment system is disclosed having 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.
