As part of an upgrade to its 8.5 mgd wastewater treatment plant, the Township of Neptune (NJ) Sewage Authority (TNSA) has issued a $3.15 million contract to Ondeo Degremont Inc. (ODI) for a Biofor® biological aerated filter system. The system will provide year-round nitrification and will reduce acute toxicity in accordance with New Jersey Department of Environmental Protection standards. ODI will supply process equipment, installation assistance and startup service.
TNSA and Birdsall Engineering, Inc. of South Belmar, NJ, selected the Biofor® system for the Neptune plant upgrade when independent testing demonstrated additional biological treatment was necessary to reduce acute toxicity to below the required limits.
"We conducted extensive tests to confirm the effectiveness of additional biological treatment in reducing acute toxicity from TNSA effluent. The Biofor® technology was considered to be an excellent fit for this upgrade and subsequent analysis and testing confirmed this," said Richard Watson of Birdsall Engineering.
A two-month pilot study finalized design parameters and confirmed the Biofor system's ability to meet stringent effluent standards. The pilot also demonstrated reliability and ease of operation.
Northeast Remsco, Inc. of Lakewood, NJ, has been awarded a contract for the installation of the system.
The Ondeo Degremont Biofor® system is a high-rate, upflow biological fixed-film system that employs a proprietary dense granular support media. The media acts as a biological contactor as well as a filter, eliminating the need for a separate clarification step.
