Effective Passive Treatment of Coal Mine Drainage

specializes in passive mine water treatment. Since 1994 HE has designed 47 passive treatment systems that have been installed largely in Pennsylvania. The design of the systems follows guidance presented by US Bureau of Mines Information Circular 9389, Passive Treatment of Coal Mine Drainage (Hedin, Nairn, and Kleinmann 1994).

Passive Treatment of Coal Mine Drainage

PASSIVE TREATMENT OF COAL MINE DRAINAGE By Robert S. ~edin,' Robert W. ~airn: and Robert L. P. ~leinmann~ ABSTRACT Passive methods of treating mine water use chemical and biological processes that decrease metal concentrations and neutralize acidity. Compared with conventional chemical treatment, passive methods

Passive treatment system Wikipedia

Oct 02, 2015· A passive treatment system is a method for removing metals from acid mine drainage. There are several types of passive treatment systems, each of which may be used on their own or in combination to treat effluents. The type of system selected is dependent upon the chemistry of the acid mine drainage and the flow of the discharge, as well as State and Federal regulations.

Passive Treatment of Acidic Coal Mine Drainage: The Anna S

The last major treatment project focused on the Anna S Mine Complex, which discharges approximately 2,800 L min-1 of AMD to Wilson Creek, a major tributary of Babb Creek. In 2003/04, passive treatment was installed for three of the four discharges from the Anna S Mine complex. The passive treatment system is the largest passive treatment

A Summary of Passive and Active Treatment Technologies

passive treatment systems often use organic matter to provide alkalinity and create reducing conditions which favour the precipitation of metal sulphides. 1 Equation 1 is applicable to sites such as coal mines where Fe, Al and Mn represent the dominant components of “Acidity”.

[PDF] DESIGNING AND SIZING PASSIVE MINE DRAINAGE TREATMENT

The passive treatment of contaminated coal mine drainage is a rapidly growing and evolving technology. Passive systems typically require less operation and maintenance efforts and are less expensive than conventional treatment systems. Three principal types of passive technologies currently exist for the treatment of coal mine drainage: the aerobic system, the compost wetland, and the
