Abstract

1417078 Removing organo-lead ions from aqueous effluents ASSOCIATED OCTEL CO Ltd 25 Oct 1974 [9 Nov 1973] 52181/73 Heading C1 Aqueous effluents containing organo-lead ions in solution in amounts of 100 p.p.m. (calculated as Pb) or less, are treated to remove the ions by feeding the effluent at a pH of 7 or above downwardly through a column of Zn particles which are substantially free of surface oxidation and periodically interrupting the flow and backwashing the column with water at sufficient pressure to fluidize the Zn particles.
