| Abstract | The report gives results of laboratory jar tests to develop data on the removal from aqueous solution of 12 metal ions of environmental concern. The project, of very limited scope, provides initial screening data only: coagulants were evaluated at only two dose levels (1.1 and 1.5 stoichiometric), no combinations of metals or coagulants were evaluated, and no attempt was made to optimize precipitation conditions. The 12 metal ions were: Al(+3), Be(+2), Bi(+3), Cr(+3), Mo(+3), Sb(+3), V(+3), Zn(+2), Ti(+3), Se(+4), As(+3), and As(+5). Treatment chemicals used were lime, sodium sulfide, alum, and ferrous sulfate. |
