Abstract
AbstractA synthetic fibers manufacturing facility is implementing an integrated phased program to upgrade its existing wastewater treatment plant (WWTP) to comply with both the Clean Water Act and the Resource Conservation and Recovery Act (RCRA). The existing WWTP consists of an influent settling basin, two equalization basins, two aeration basins with low‐ and high‐speed aerators, three secondary clarifiers, post‐aeration, and belt filter press dewatering with on‐site landfilling. The existing WWTP will be replaced with a tank‐based system that will include equalization, biological treatment, clarification, effluent filtration, and effluent diffusion. RCRA regulatory compliance incorporated the Corrective Action Program, the Toxicity Characterstic Rule, the Land Disposal Restrictions, and closure/postclosure requirements. Clean Water Act compliance incorporated the Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF) effluent guidelines, effluent toxicity, and general water quality requirements. Logistically, project implementation involved fast‐track design and construction, close regulatory interface, and maintenance of production process continuity.
