All dissolved salts are removed from the water with full demineralization.
The ion exchanger is loaded with positively charged H+ as well as negatively charged OH- ions. If the water to be treated is now passed through the ion exchanger, all positively and negatively charged ions are replaced or adsorbed (= bound to solid state).
As already described in the section "The principle of ion exchange", ultrapure water is now the result of the emission of H+ and OH-.
(H+) + (OH-) = H2O
As opposed to distilled water, fully demineralized water is not acidic and has decisive advantages compared to osmosis water due to the removal of carbon dioxide.
• Protection against corrosion and insoluble deposits by the removal of chlorides, sulfates and nitrates from the water.
• Depending on the quality of the incoming water, the electrical conductivity drops down to < 0.1 µs/cm1 (TREF25).
• The pH value is in the neutral range because carbon dioxide and silicic acid is removed.
• The low conductance value and neutral pH remain constant and thus guarantee long service life of your machines.
• Dissolved inorganic ions are easily removed.
The resistance after treatment is 18.2 MΩ (at 25 °C) with a TOC value of <1 ppb.
