VERFAHREN ZUR AUFBEREITUNG VON INSBESONDERE NITRATHALTIGEM WASSER

摘要

In a process for the treatment of in particular water-containing nitrate, such as, for example, ground water, brackish water or the like, the water is separated into a low-nitrate permeate and a high-nitrate concentrate by means of reverse osmosis and the latter is evaporated until precipitation of the solid. In order to be able to operate such a process more cost-efficiently, the concentrate is freed from hardness formers, concentrated by means of a membrane separation process to give a salt solution, which is then evaporated.
