Abstract:
The specification describes an oxidation and adsorption method for removing contaminating materials (pollutants) from aqueous liquids. The liquids are first subjected to an electrochemical treatment for the purpose of coagulation or agglomeration and partial oxidation by addition of NaOCl. Following this, using sedimentation and/or flotation, the agglomerated and coalesced sludge is removed from the liquid. In the liquid an excess of OCl.sup.- remains and this liquid, enriched in this manner, is supplied to adsorption columns, in which inorganic adsorption compositions are located having a high specific surface area so that a further oxidation is achieved by the excess OCl.sup.-, together with a partial adsorption and by addition of O.sub.3, complete oxidation is achieved. The organic contaminating materials are converted into CO.sub.2 products of adsorbing materials of different grain sizes and specific surface areas made of inorganic materials, following which the CO.sub.2 escapes from the liquid and is stored. The thus cleaned liquid then leaves the oxidation and adsorbing columns.
Abstract:
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.
