Cochrane Ultra Pure Water

An EDI water treatment system is a continuous electrically driven membrane and resin ion separation technology. RO product water  from the DELTA  RO unit enters the EDI module through an inlet valve and then enters stack of cells with cation and anion membranes separated by spacers. On opposite ends of the stack is a cathode and anode – each providing an electrical potential to drive the cations and anions through the respective one way membranes to a waste channel. The product and waste channels contain a thin layer of mixed bed resin to provide a conductive path to facilitate the process. The result is a highly efficient system that removes all dissolved solids with very close to neutral pH. The purified water is then piped out of the stack. Modules of different flow rates can be plumbed together to provide higher flow rate capacities.
