The specification describes a method for removing pathogenic germs and dissolved organic substances from liquids. Kefir milk acid bacteria in the form of a centrifugate, obtained from washing-out Kefir mold cultures are added to the liquid after suitable electrochemical precleaning. The liquid mixed with the bacteria is passed over a cylindrical column, whose filling bodies consist of cylindrically shaped fabric of antimagnetic stainless steel with a large surface. On this the microorganisms of the Kefir group become deposited, from a biological lawn and in the case of the supply of atmospheric oxygen and multiple passage of the liquid through the column the organic liquid contaminating materials finally take up the pathogenic germs as nutrient material so that owing to the microbiological processes of the Kefir bacteria the liquids are freed from these materials.
