AQUABOX 50 and MARABU Packed Biological Reactor System June 2000
This bilateral SITE demonstration of the AQUABOX 50 and MARABU packed biological reactor systems was designed with two primary and three secondary objectives. The objectives were chosen to provide potential users of the technology with the information necessary to assess the applicability of the biological reactor technology for treatment of groundwater at other contaminated sites. The following primary and secondary objectives were selected to evaluate the technology:
- P1 Demonstrate greater than 95 percent average removal efficiency for total BTEX and greater than 60 percent average removal efficiency for the three most prevalent PAHs (acenaphthene, fluorene, and naphthalene) for the overall system. The overall system includes the AQUABOX 50, MARABU, and sand filter, but excludes the activated carbon system component.
- P2 Measure the removal efficiencies for BTEX and the three most prevalent PAHs across each of the treatment units, including the AQUABOX 50, MARABU, and sand filter.
- S1 Determine the percent of total BTEX and naphthalene that is stripped from each aerated component of the system.
- S2 Document the physical and chemical characteristics of the treated water that could affect the performance of the evaluation system and document how these parameters change with treatment.
- S3 Document the capital and operating costs of the SWD AQUABOX 50 and MARABU packed biological reactor system based on observations during the evaluation and data from the engineering designers and from the operator of the system.
