Background

  • Laborator y microcosm tests performed at Penn State Univer sity to determine the e ectiveness of CHITOREM in treating mine in¬uenced water (MIW).
  • MIW collected from Kittanning Run in Altoona, PA exhibiting pH of 3.21, acidity of 192 mg/L and alkalinity of 0 mg/L.
  • CHITOREM ch itin complex compared with mushroom mulch and sodium lactate as potential biochemical reactor substrates.

Project Status

  • Over 99% Fe and Al removal in 9 days with CHITOREM chitin complex.
  • Mn decreased by 81% in 37 days.
  • pH increased to 6.79 and acidity decreased from 192 to -114 mg/L.
  • Sulfate reduced from 489 mg/L to 303 mg/L in 2 days and exhausted at 37 days confirming the activity of sulfate reducing bacteria.
  • CHITOREM chitin complex significantly outperformed other substrates for MIW treatment.
