  • Evaluation of the FCI Fiber Optic Chemical Sensor (FOCS)™ for BTEX in Water Against EPA`s Method 8020

    The patented fiber optic chemical sensor (FOCS)™ technology is based on the principle of modulation of light transmitted along an optical fiber. A portion of the cladding of a small segment of the optical fiber is replaced by a proprietary chemical coating, which changes the refractive index in the presence of hydrocarbons. This change in the index is proportional to the concentration of ...

  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...
