  • Process for the galvanic purification of the waste waters
    Patent number: 4035269
    Abstract: A method for removing metals from waste liquids without the use of an externally supplied source of current. The method consists in (i) immersing in the waste liquid at a pH of less than 3.5, two materials which are different from each other and the metal to be removed, one of the immersed materials being electropositive, the other being carbon or electronegative, (ii) connecting the two immersed materials to each other, thus giving rise to an electric current, (iii) precipitating the metal or metals to be removed, and (iv) recovering the purified waste liquid.
