Abstract

In the process, the untreated water is deionised and then filtered to remove organic impurities. The deionised water is continuously filtered and the filtrate is circulated in a circulating flow and returned to the filter. During this, the extra-pure water which is required in each case is removed from the circulating flow. A membrane ultrafilter whose filter residue is continuously removed as concentrate is used as filter. It is cleaned from time to time. This makes it possible substantially to remove bacteria and pyrogens from the extra-pure water, and the undesired variations in quality of the extra-pure water are greatly reduced.
