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.
