The best method for ecological water treatment : SEPTRON

Compared with conventional EDI modules, the special hydrodynamic design of the SMH 3000 permits a higher sanitisation flow rate of up to 70 per cent of the ultrapure water output with a pressure drop of 1 bar. The innovative electrodeionisation method of CHRIST fully complies with our responsibility for the environment. Pre-treated water (e.g. of a reverse osmosis stage) flows into the patented SEPTRON® module, where it is continuously deionized.

This is carried out with an electric current, without the need for chemicals and with only a low power consumption. Water enters a chamber which is filled with an ion exchanger. The electrical potential applied to the electrodes causes charged ions, such as sodium and chloride, to pass through the ion exchange membrane into a concentrate chamber, from which they are discarded. The ion exchanger inside the SEPTRON® module reduces the electrical resistance, which means that the power needed to achieve the desired deionisation is also low.

This method permits the removal of ionic components out of the water without increasing the total amount of salt (from the viewpoint of the entire process).
