Title (EN) METHOD OF WATER PURIFICATION
(FR) PROCEDE DE PURIFICATION D'EAU
Abstract:
(EN) A method of water purification provides for introducing into the water a sorbent-suspension obtained by electroerosive dispersion of ferrous metals in the water and containing no more than 3 % of magnetite, mixing and subsequent separation of the solid phase. The suspension is fed into the water at a quantity of 3 to 120 g of dry substance for 1 g of impurities. Mixing of the suspension with the water is effected at a temperature of 20-70 °C.
(FR) Un procédé de purification d'eau consiste à introduire dans l'eau une suspension de sorbant obtenue par dispersion électroérosive de métaux ferreux dans l'eau, et ne contenant pas plus de 3 % de magnétite, à procéder à un mélange puis à une séparation de la phase solide. La suspension est acheminée dans l'eau en une quantité de 3 à 120 g de substance sèche pour 1 g d'impuretés. Le mélange de la suspension avec l'eau est effectué à une température comprise entre 20 à 70 °C.
