EnSolve’s PetroLiminator System Uses Patented Bioremediation Technology to Remove Emulsified Oil EnSolve Biosystems has been awarded a contract from the U.S. Maritime Administration (MARAD) to supply a PetroLiminator Oil Water Separator for treating bilge water from its fleet service craft at the Suisun Bay Reserve Fleet, Calif. The patented PetroLiminator system uses a three-stage process to treat the oily water. In the first stage, free-phase oil is separated and removed to a collection tank, where it can be recycled or burned. In Stage II, the oily water passes through a bioremediation chamber containing hydrocarbon-degrading microbes, which consume the emulsified oil droplets.
