Mining Wastewater

The main formation condition and harmfulness of the acidic mining waste water's were analyzed in this paper. The treatment technology of the acid mine drainage's was briefly introduced. The research development of acid mine drainage was summarized in recent years. It was the fact that developing the efficient, cheap, safe and easy treatment technology of acid mine should be necessary and inevitably and some success management experiences of acidic waste water were applied in acidic mining wastewater.

Interesting Alternative

The metal-finishing and tannery industries have been under strong pressure to replace their current wastewater treatment based on a physicochemical process. The electrodialysis process is becoming an interesting alternative for wastewater treatment. Electrodialysis is a membrane separation technique, in which ions are transported from one solution to another through ion-exchange membranes, using an electric field as the driving force. Blends of polystyrene and polyaniline were obtained in order to produce membranes for electrodialysis. The produced membranes were applied in the recovery of baths from the metal-finishing and tannery industries. The parameter for electrodialysis evaluation was the percentage of chromium extraction. The results obtained using these membranes were compared to those obtained with the commercial membrane Nafion 450.
