Fly ash from solid waste incineration plants is a source of significant mass flow Zn- and Pb-containing waste. Acidic leaching removes most heavy metals fly ash, but leads to high concentrations soluble salts in the solution, resulting saline solution enriched metals. Common treatment methods cause voluminous sludge that mostly disposed as hazardous hence loss Zn other On laboratory scale, precipitation experiments with 2000 mg/L were performed investigate impact salinity (0 >70,000 Cl, 0...
The usual way to treat heavy metal containing industrial wastewater leads large amounts of hydroxide sludge.In general, the concentration non-ferrous metals in sludge is too low for an efficient recovery these elements and consequence, secondary raw materials dissipate.New procedures were developed from traces up 25 g/l like Cu, Ni, Zn, Mn, Pb, Sn, Pd Ag.Using modified ferrite process with Fe/M = 2/1 specific products free can be produced.The precipitates are most cases a mixture ferrite,...
