Electro-diaphragm analysis

The method of electro-diaphragm analysis (also membrane cell electrolysis) based, as the name suggests, on the long-known method of electrolysis. In contrast to this, in electrodiaphragmal analysis, however, the anode is separated from the cathode by an ion-selective membrane (see diagram).

In August 2007, on-site production of neutral sodium hypochlorite by means of membrane cell electrolysis was added to the list of approved germ reduction methods in §11 Drinking Water Ordinance.

Since the release of the process, numerous plant types have been developed. Mainly, these differ mainly in the ingredients of the produced disinfectant (anolyte), the required amount of sodium chloride (salt) and the required space.
