- Chitin Complex Inherent Buffering Agent


Long-lasting, inherent buffering agent perfect for excavations and acid mine drainage. Long-Lasting: Provides both a fast and slow release carbon source and nutrients.

Inherent Buffering Agent

  • Contains calcium carbonate which serves as a natural buffering agent for low pH applications.

Niche Application for Acid Mine Drainage

Contaminants Treated:

  • Halogenated aromatic and aliphatic hydrocarbons such as PCE
  • Oxidizers such as perchlorate
  • Explosive and ordnance compounds such as RDX
  • Reduction of metals, such as arsenic, chromium, uranium, and manganese.

Treatment Configurations:

  • Open excavation backfill
  • Source treatment
  • Permeable reactive barriers
  • Bioreactor treatment
  • Constructed wetlands

Delivery Methods:

  • Direct push methods
  • Hydraulic fracturing

CHITOREM has been used successfully at PCE sites with low pH aquifers.

At a field site with pH in the range of 4 -5.5, addition of CHITOREM to the open excavation resulted in contaminant concentrations below MCLs in less than two years.
