technologyComment of water production, deionised (Europe without Switzerland): The process includes an anionic resion or combined cation/anion exchange resin. The unit is operated with counterflow regeneration. Obtained water quality: about 1-0.1 uS/ cm for the conductivity and a silica content (as SiO2) of 5-25 ug/l. For the water source, tap water from a public supply with a total hardness of 1.71 mol/m3 (range 0.7 - 3.2) was assumed.
