Abstract
The Bureau studied two novel approaches to the manganese problem. One was an inexpensive pipeline treatment system device known as the in-line aeration and neutralization system (ils), which was developed by the Bureau to aerate and neutralize mine water. At three mines with influent mn concentrations of 10 to 68 mg/l, use of the ils reduced mn concentrations to less than 2 mg/l at ph values of only 6.8 to 7.3 Another novel approach to mine water treatment is the construction of wetlands on mined sites. Results from ongoing tests indicate that this biological treatment can be engineered to optimize either iron or manganese removal. Moderate mn concentrations (14 to 30 mg/l) have been reduced to 2 to 6 mg/l in constructed wetlands at four minesites in western Pennsylvania.
