Toxicity Treatment of Mine Final Effluent

Six treatment options were evaluated to remove or reduce toxicity caused by the suspected contaminants. The six treatments investigated included: (1) Granular activated carbon (GAC) + zeolite; (2) air stripping + GAC; (3) zeolite + GAC; (4) multistage GAC; (5) alkaline chlorination + dechlorination; and (6) bentonite clay based polymers.

Mine Water Treatment Solutions for Discharge and Re …

In order to minimize water management problems due to excess water at a mine site, or to address changing constituents or contaminant levels over time, Pall has designed its water treatment system to be highly "modular" and offers it in a multi-rack-based configuration.
