Fusion Bonded Epoxy Tanks for Physical Wastewater Treatment: Robust Containment for Screening, Sedimentation, and Filtration

Physical wastewater treatment is the critical initial stage in almost every purification facility, removing coarse materials and bulk suspended solids before advanced biological or chemical processes begin. This stage, encompassing screening, sedimentation, and filtration, is characterized by high levels of abrasion, continuous dynamic loading from flow, and the corrosive nature of raw effluent. The containment vessels must be exceptionally robust to withstand the mechanical wear from grit and the stress from heavy mechanical equipment within large basins. The Fusion Bonded Epoxy (FBE) Tank provides this necessary combination of structural strength and abrasion-resistant protection. At Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel), we engineer FBE bolted steel tanks to deliver durable, low-maintenance containment that anchors the efficiency of primary wastewater treatment.

The Abrasive and Dynamic Environment of Physical Treatment

Infrastructure dedicated to physical wastewater treatment is subjected to unique and severe operational challenges:

Abrasive Wear from Solids: Processes like screening, sedimentation, and filtration concentrate large amounts of grit, sand, and non-biodegradable solids. The internal tank surfaces are constantly scoured by these abrasive materials, demanding a hard and resilient lining to prevent substrate erosion.

High Hydraulic and Dynamic Loads: Primary clarifiers and large sedimentation basins handle immense, continuous flows. The vessels must be structurally sound to manage extreme hydrostatic pressure, and the installation must withstand the torque and load exerted by heavy internal mechanisms like scrapers, rakes, and filters.

Corrosive Raw Effluent: As the first line of defense, these tanks contain the raw, untreated waste stream, which often contains high concentrations of corrosive agents like (in sewage) or strong chemicals (in industrial waste). The containment must be robust against this continuous chemical attack.

Need for Accessibility and Maintenance: Physical treatment tanks require frequent inspection and maintenance (e.g., removing settled grit). The tank structure must support easy access and resist damage from jet cleaning or periodic desludging operations.

The solution must be robust containment that can absorb high physical and hydraulic stresses while providing permanent corrosion protection.

The FBE Solution: Robust Containment for Screening, Sedimentation, and Filtration

Center Enamel’s Fusion Bonded Epoxy Bolted Steel Tanks are engineered for the rigorous demands of physical wastewater treatment, ensuring robust containment for screening, sedimentation, and filtration stages:

Hard, Abrasion-Resistant Surface: The FBE coating is a high-density, factory-applied polymer molecularly bonded to the steel. This creates a tough, hard-wearing surface that resists the continuous scouring and erosion caused by the high concentration of grit and suspended solids in raw wastewater.

Structural Integrity for Clarifiers: Constructed from high-tensile, factory-engineered steel, FBE tanks offer the superior structural strength required for the large diameters and deep wall depths of primary and secondary clarifiers. This stability is crucial for supporting heavy internal mechanisms like sludge scrapers and skimming arms.

Corrosion Resistance to Raw Effluent: The FBE barrier provides a permanent defense against the corrosive gases and chemical agents present in raw, pre-treated sewage and industrial effluent, protecting the steel substrate from the moment the wastewater enters the facility.

Versatility Across Stages: FBE tanks offer a standardized, robust platform for all physical treatment stages, including circular clarifiers, rectangular basins (via modularity), and grit chambers, simplifying facility design and material specification.

Rapid, Quality-Controlled Installation: The modular, bolted design ensures fast, predictable construction with factory-verified quality, resulting in a reliable asset that begins protecting the pre-treatment process quickly.

Product Industry Application: FBE Tanks in Physical Treatment Infrastructure

The high structural strength and durability of FBE tanks make them indispensable for all phases of physical wastewater treatment:

Grit Chambers and Skimming Tanks: Providing robust containment to manage the highest abrasive load and facilitating the removal of heavy solids and surface scum.

Primary Clarifiers (Sedimentation): FBE tanks serve as the main circular or rectangular basins for gravity settling of suspended solids, relying on the tank's size, structural integrity, and resistance to raw effluent corrosion.

Secondary Clarifiers: Used downstream to settle biological solids (activated sludge), requiring precise structural integrity for optimal settling characteristics.

Equalization Basins: Used to stabilize the highly variable flow before it enters the physical treatment train, protecting the system from hydraulic shock loads.

Sludge Thickeners: Providing robust containment for concentrated sludge, which is dense and highly abrasive, often requiring the use of specialized scraper mechanisms.
