Demineralization cartridge \/ VE cartridge<\/h1>\n<\/div>\n\n
\n

A demineralization cartridge \/ VE-cartridge is used to produce so-called demineralized water<\/a> in small quantities of up to 4 m\u00b3\/week; beyond this, demineralization systems that can be regenerated automatically<\/a> are generally used. In this process, all ionogenic substances are removed from the input water, often city water, and replaced with H2O. This produces a high-purity demineralized water (also: DM water or \u201cforklift water\u201d or \u201cbattery water\u201d) for industrial purposes with a conductance of < < 0.1 \u00b5S\/cm in ultrapure water applications up to 0.056 \u00b5S\/cm. <\/p>\n\n\n\n

High-purity water is often required in industrial processes, e.g. in laboratories, for post-purification of pre-purified water or when filling forklift truck batteries. The typical parameters of the available water, usually city water \u201cfrom the tap\u201d, are generally not sufficient, as particularly limescale deposits of the hardness formers calcium and magnesium are disruptive in the processes. <\/em>The VE cartridge or demineralization cartridge contains an ion exchanger resin<\/a> Mixture of cation exchanger resin and strongly basic anion exchanger resin, typically in a ratio of 40:60, so-called mixed bed resin. The strongly acidic cation exchanger removes the cationic ion loads such as sodium, calcium, magnesium and also the copper permissible according to Drinking water ordinance up to 2.0 mg\/L. The strongly basic anion exchanger removes anionic ion loads such as corrosive chlorides or sulphate. Within the scope of their respective capacities, the cation exchanger releases H+<\/sup> ions in exchange and the anion exchanger releases OH– <\/sup>ions in exchange. Together, H20is produced in the outlet of the system instead of the ions in the inlet water. Due to the mixture of the two ion exchangers, the removal of ionogenic substances ensures a low conductance value of typically < 0.1 \u00b5S\/cm at the outlet of the demineralization cartridge \/ VE-cartridge. The capacity of the cartridge depends on the amount of resin used, its type and the composition of the feed water (salt load). Typically, however, a capacity of approx. 2 m\u00b3 of demineralized water can be expected from the average city water of around 350-550 \u00b5S\/cm with a 30L demineralization cartridge and approx. 4 m\u00b3 of demineralized water with a 50L demineralization cartridge. Full capacity utilization can be achieved by connecting 2 VE cartridges in series. After replacing the loaded 1st VE cartridge, the 2nd VE cartridge moves to the 1st position Once the capacity of the demineralized water cartridge is exhausted<\/a>, it is regenerated externally as an ion exchanger regeneration<\/a> service so that it is not overrun<\/a>. <\/p>\n\n\n\n

The demineralization cartridge does not generate any waste water during the production of demineralized water as part of the process water treatment. However, when using the demineralized water product from the demineralization cartridge for operational purposes (e.g. rinsing of workpieces), operational wastewater is still generated, the indirect discharge of which into the municipal wastewater treatment plant is subject to treatment and approval<\/a>. <\/p>\n\n\n\n
