Translation of "Hochreines wasser" in English

Preferably, high-purity water or high-purity aqueous solutions are used.

The result is soft, high-purity water.

Here highly pure water is used between the projector lens and the wafer surface as an immersion liquid.

In December, the Industriepark Höchst unveils the world's largest distribution system for purified water.

The result is a very soft, high-purity water.

Furthermore, industry is increasingly using high-purity water for highly sensitive manufacturing processes.

The Process IC requires ultrapure water to run analyses.

Ultra-pure water is split into hydrogen and oxygen through electrical energy in the proton exchange membrane.

In the case of the liquids, preferably high-purity water, having a conductance of preferably below 0.14 uS, particularly preferably of 0.08 uS, is ejected at a pressure of preferably 2 to 20 bar.

In the case of liquids, high-purity water, with a conductance of preferably below 0.14 ?S, particularly preferentially 0.08 ?S, is preferably ejected at a pressure of preferably 2 to 20 bar.

The entire interior of the housing 30 is filled with a sound-carrying liquid 38 with a high dielectric constant, e.g., highly-purified water with a conductivity less than 10 ?S/cm, or silicone lubricant preferably glycerol.

This matches the fact that the coolant system of nuclear reactors contains highly pure (deionized) water, to which only a slight quantity of boron is added.

This takes into account the fact that a cooling system of a nuclear power station contains highly pure deionized water, to which optionally a slight amount, maximally 2200 ppm, of boron is added.

A condition therefor is, however, that very pure or ultra pure water is used as a cooling liquid which comprises only a very low electrical conductivity.

The method according to the present invention is particularly advantageous from a technical point of view (i.e., the products are a high-quality concentrate as well as a reusable high-purity water) as well as from an economical point of view (low energy requirement, low investment).

Devices of such types, reverse osmosis (RO) systems, are particularly used in combination with hemodialysis devices to obtain sterile high-purity water from tap water for preparing the dialysis liquid. SUMMARY OF THE INVENTION

In the proton exchange membrane (PEM), ultrapure water is split into hydrogen and oxygen by electric current.

Therefore the hygienic production requires ultrapure water (highly purified water) which is used for the steam production for sterilisation.

Highly purified water (Water For Injection: WFI) is required for manufacturing products injected directly into the bloodstream or administered as eye or nose drops.

According to information in the literature, the liquid media are usually prepared using high-purity, pyrogen-free water, corresponding to the WFI quality (water for injection) of Pharmacopeia Europe.

The present invention refers to an RO system with which ultrapure water is preferably produced for the operation of dialysis devices.

Furthermore, high-purity water is also required in the semiconductor industry, for example, to rinse silicon wafers, in particular after etching processes.

Preferably, the phase can be dispersed in high-purity water or in a mixture of high-purity water and ethanol, and then distilled off.

High-purity water, in addition, is especially also required in the semiconductor industry, for example, for rinsing silicon wafers, in particular after etching processes.

For injection into the fuel gas, as a rule highly-purified, demineralized water is used, as is also used for NOx reduction when operating on oil.

The advantage of this arrangement is that in a fuel cell system which is operated with an operating medium (such as preferably hydrocarbon or an alcohol or an ether), the ion exchanger unit can be used to clean a mixture of water and the operating medium. This makes it possible to substantially prevent damage to components and lines in the flow path for the mixture caused by corrosive high-purity water, and also makes it possible to suppress harmful deposits on catalytic components.

First, ultrapure water or RO water and/or preferably purified or filtered air can be conveyed through it, for example, for the purpose of dissolving the dry concentrate.
