Frac Biologics, Inc., is a company formed to provide innovative, cost-effective treatment of frac water and acid mine drainage Frac Biologics technology uses an on-site, environmentally-friendly process to remove the heavy metals from the recovered frac water. This unique technology uses naturally-occurring bacterial biofilms, which are complex, slime-enclosed communities that are found in all ecosystems. The removal of dangerous metals by biofilms is rapid and highly efficient. Acid Mine Drainage (AMD) results when atmospheric oxygen penetrates rock and oxidizes pyrites (ferric sulfides), to form sulfuric acid, which then etches the rock and liberates iron salts. AMD occurs very rarely in nature, even in areas of very high pyrite concentration, because a biologically active crust develops on all rock surfaces through the oxidation of small amounts of minerals, the accretion of dust, and the growth of microbial biofilms.
