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.

Resource utilization of pickling wastewater (waste acid)
Resource utilization of pickling wastewater (waste acid)

A large number of pickling wastewater (waste acid) will be produced in iron and steel processing enterprises. The concentration of heavy metal ions in this kind of wastewater is high. As long as the concentration of heavy metal ions can be reduced, the regenerated acid can be returned to the pickling section for recycling.
