ChitoRem® Chitin Complex

ChitoRem® Chitin Complex is a 100% natural product that is comprised of chitin (a natural polysaccharide), proteinaceous material, and calcium carbonate. This product is used in bioremediation as a carbon source and subsequent electron donor for the microbial degradation of chlorinated solvents, heavy metals, perchlorates, and acid mine drainage in contaminated aquifers. It is solid material that provides both a readily soluble carbon substrate as well as a slow-release carbon source. It is perfect for open excavations, direct push applications, acid mine drainage and low alkalinity halogenated solvent sites.

Technical Details & Test Data

Dechlorination in Open Excavations

Former Dry Cleaning Site: Jacksonville, FL

Following excavation of the source area, CHITOREM® was applied to the excavated area.  Dechlorination of residual PCE and its daughter products to below MCLs was seen in less than two years.

Dechlorination in Low pH Aquifers

Electroplating Facility: Ormond Beach, FL

CHITOREM® has been used successfully at sites with low pH aquifers.  At a site with pH in the range from 4-5.5, dechlorination of residual PCE and its daughter products to below MCLs was seen in less than two years.

Acid Mine Drainage Applications

National Tunnel Superfund Site: Black Hawk, CO

CHITOREM® has been used successfully as a carbon substrate in biochemical reactors:

  • Shown to remove metals including Fe, Zn, Cu, and Mn to below treatment objective levels.
  • Increased pH from 4.55 to 6.98.
  • Increased alkalinity from 0 to 2,000 mg/L (as CaCO3).

Storage & Handling

Shelf Life
2 Years (Unopened), 1 Year (Kept in Dry)
Storage and Shelf Life
  • Store unopened under dry conditions at temperatures between 35°F and 85°F.
  • The shelf life of the unopened products is 2 years
  • If kept dry, opened product can be stored for 1 year
  • Equipment decontamination should follow site-specific requirements. In most situations, any product residual should be flushed into the aquifer and then chased with clean water.
