Limestone Buffered Organic Substrates (LBOS)

Limestone Buffered Organic Substrate passively treats acid mine drainage (AMD) and coal pile ash ponds and runoff.

A passive treatment media for acid mine drainage (AMD), coal pile ash ponds and runoff is engineered to overcome armoring that causes other limestone-based passive treatment systems for AMD to fail. Rather than rely solely on alkalinity provided by limestone, LBOS generates additional alkalinity within the treatment system.
