| 摘要 |
The invention relates to a method and an installation for producing pure water from untreated water, in particular, surface water. Said method comprises a final treatment stage including a membrane filtration, which is preceded by at least one biological treatment stage (biosorption stage). The aim of the invention is to provide a method and an installation of this type, which permit ultrapure water to be produced from untreated water in the most cost-effective manner possible, whilst at the same time suppressing biofouling to a great extent, without the addition of biocidal active substances or other chemical substances. To achieve this, an inoculum is added to and incubated with the untreated water in the biosorption stage, said inoculum being produced by the external reproduction of at least one part of the biocenosis contained in the untreated water. |
