Therefore, the water supply, which contains heavy metals, imports 5-7% of iron with a dispersion of 25-150 mkm, which results in a minimum of 30 WATER PREPARATION AND THEREFORE ARE AVAILABLE FOR ACCOUNTING PROCESSES - SEDIMENTS.

Abstract

L'invention concerne le traitement des eaux et peut être utilisée pour extraire des ions métalliques, des nitrates ainsi que d'autres impuretés pendant la purification d'eaux d'égoût, de lavage et autre. On procède à la purification par sorption des impuretés au moyen d'une suspension obtenue par dispersion par électroérosion dans l'eau d'éponge de fer obtenu, à son tour, par réduction de pellets de minerai de fer.
