Principle of operation
The disinfectant solution is produced through diaphragm electrolysis, which is based on the
electrolysis technology in which a semi-permeable membrane (5) separates the anode and
cathode compartments and thus enables an ion exchange with simultaneous separation of
the liquids.

In the electrolysis chamber, negatively charged ions of the salt solution (Cl
-
, OH
-
) are
attracted to the anode (3) where they release electrons. In particular hypochloric acid (HCIO)
and further highly reactive oxidants are produced. In addition, innumerable micro-bubbles
develop, which produce the desired physical destruction (hence disinfective) effect on the cell
membranes of bacteria and amoeba. The interaction of all these factors results in an
extremely strong disinfection effect.
The positively charged ions (Na
+,
H
+)
migrate to the cathode (7) to receive electrons there. In
this process, an alkaline solution consisting of diluted caustic soda (NaOH) develops, which
can be used e.g. as cleansing agent.
Depending on the production mode, the following media are produced:
Anolyte
Disinfectant solution in the acidic range (pH
3)
Very high ORP
+1,100 mV
Catholyte
Cleansing agent in the alkaline range (pH
11)
ORP
-800 mV
Anolyte
neutral
Disinfectant solution in the neutral range (pH ≈ 7.2)
Very high ORP
+650 mV
The electro-activated disinfectant solutions may differ in their properties. The efficiency of the
diaphragm electrolysis process can be affected by variable factors such as water temperature,
salt concentration, and flow rate.
