Electrolysis of potassium dichromate acid wastewater with iron electrode
Polyacrylamide for steel wastewater
Polyacrylamide for steel wastewater

The treatment of mine acid wastewater generally adopts the lime neutralization method. Iron and steel plant wastewater treatment uses anionic polyacrylamide as a flocculant to treat wastewater produced in steel plants. Anionic polyacrylamide only needs to be used in industrial wastewater treatment.

Iron, in titanium‐dioxide plant industrial ,wastewater, is removed by limestone in the dune sand into which the waste is disposed. A pilot scale laboratory column experiment to investigate the interactions between the waste and the sand showed that the ,iron, was removed from solution as ,iron, carbonate just beyond the ,acid, neutralization zone.
