Fortune 100 Manufacturing Plant Utilizes Wastewater Treatment Plant to Bring Highly Complex Wastewater into Industry Compliance
Project Overview
When a Fortune 100 manufacturing facility was challenged to bring their complex wastewater up to industry compliance standards, SAMCO was selected to design, build, own, operate, and maintain (DBOOM) a major wastewater treatment plant (WWTP) at the company’s primary location in the Northeast.
Objective
DBOOM WWTP at client’s main manufacturing location to treat highly complex and variable wastewater per industry compliance standards, including:
- Oil and grease < 60 ppm
- Total suspended solids (TSS) < 100 ppm
- Zinc < 1.5 ppm
- Chromium < 0.5 ppm
- Phenol < 0.8
Scope of Service
The client worked with SAMCO to develop an effective solution that comprised a treatability/pilot study, detailed design/engineering, system fabrication/integration, field installation, commission/ startup, and ongoing operation and maintenance (O&M)
Challenges
- Highly complex contaminants and varied flow
- Plant expansion/increased wastewater volume
- Stringent discharge limitations
- Reduce O&M cost
Solution
Trucked in from multiple locations, the client’s contaminated waste resulted from press pit, zyglo dye, fume exhaust, and high pH etching manufacturing procedures, among others. SAMCO efficiently utilized source-segregation strategies to reduce contaminant loads, chemical feed, and sludge waste. Dissolved air flotation was used in lieu of a clarifier to remove suspended solids, reduce chemical feed and sludge waste, handle the added expansion load, and provide the client with a less-than- one-year payback. A prepackaged system and modular design enabled quick and easy installation with guaranteed performance and future add-on capabilities, and SAMCO also included programmable logic controllers (PLC) that automate monitoring of flow, temperature, pressure, and resistivity.
