SBR Technologies conducts develops a design for the biological treatment of groundwater contaminated with volatile organic compounds

Challenge

SBR Technologies, Inc. (SBRT) was hired to conduct laboratory treatability studies in order to assess the feasibility of biological treatment of contaminated groundwater samples from a large chemical manufacturing site in northern New Jersey. Contaminants identified in groundwater samples included BTEX, acetonitrile, methylene chloride, chloroform, and other halogenated volatile organic compounds (VOCs).

Biological treatment of the samples was evaluated in both the SBR and the SBBR. The laboratory study demonstrated conclusively that biological treatment of the groundwater was feasible.

Benefits Achieved

Specific results from the study included:

  • Greater than 95% removal efficiencies for BTEX and acetonitrile were achieved in the reactor systems.
  • Between 50 to 60% of chloroform and methylene chloride
  • More than 95% of other chlorinated VOCs were also removed by the systems

Based on these results, SBRT developed design bases for pilot and full-scale treatment systems.
