Flat Wall Process Tanks
Engineered Atmospheric Tanks for Industrial Separation and Wastewater Processing
We manufacture flat wall atmospheric process tanks designed to support separation, clarification, and industrial wastewater treatment across energy and water infrastructure markets. Built-to-specification, these tanks provide dependable fluid management and controlled-flow conditions for facilities requiring hydrocarbon removal, solids separation, and regulatory compliance.
Each tank is engineered to integrate with CPI systems, API gravity separators, DAF clarification units, filtration systems, vapor-control equipment, and associated process components. Designs are customized to align with specific operating parameters, chemical compatibility requirements, and site conditions, ensuring long service life and consistent performance under variable process demands.
Fabricated to applicable industry standards and supported by advanced coatings and corrosion resistant material options, these tanks serve as essential components within high-efficiency separation systems and multi stage treatment processes across refineries, petrochemical plants, oil and gas production sites, and industrial wastewater facilities.
Our flat wall process tank offerings
Corrugated Plate Interceptor (CPI) Tanks
CPI Tanks provide high efficiency primary separation for oily wastewater streams, using inclined corrugated plate packs to remove free oil and suspended solids. Ideal for industrial wastewater pretreatment, produced water systems, and refinery operations requiring compact, low energy gravity separation.
API Tanks
API Tanks support upstream and midstream oil and gas operations as reliable storage and process vessels for production liquids, crude oil, and produced water. These tanks enable gravity settling, basic separation, and temporary storage within tank batteries, central facilities, and industrial sites.
Dissolved Air Flotation (DAF) Tanks
DAF Tanks deliver advanced clarification for wastewater applications where high removal of suspended solids, fats, oils, and greases is required. These units are engineered to integrate with pressurized air saturation systems, flocculation equipment, skimming assemblies, and downstream filtration.
