FBE Leachate Storage Tanks: Epoxy-Coated Steel for pH<2 Streams

An FBE leachate storage tank is a bolted steel vessel protected by Fusion Bonded Epoxy cured at 180-220°C to 250-450 µm, built for aggressive landfill leachate often below pH 2. The coating resists pH 1-14 and is adhesion-tested to ASTM D4541. Engineered by Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) to AWWA D103-09 and ISO 28765, capacities span 20-5,000 m3.

An FBE leachate storage tank is a bolted steel vessel whose interior is protected by Fusion Bonded Epoxy powder cured at 180-220°C to a 250-450 µm coat. The epoxy resists the acidic, ammonia-rich leachate common below pH 2 for a 30-50 year life. Capacities run 20-5,000 m3, and bolted build avoids on-site coating work at the landfill.

• Coat: FBE 250-450 µm.
• Cure: 180-220°C.
• pH: resists 1-14.
• Range: 20-5,000 m3.

FBE leachate tanks use bolted panels with 8.8-grade fasteners, a sealed or vented roof, and manways and flanges for transfer. Unlike enamel, FBE is a thermoset epoxy with high adhesion verified by ASTM D4541 pull-off testing. Alternatives are GFS enamel or rubber-lined steel, but FBE offers a thick, impact-tolerant barrier at low to mid volume.

• Bolts: 8.8-grade.
• Roof: sealed or vented.
• Adhesion: ASTM D4541.
• Edge: thick, impact-tolerant.

They serve landfills, transfer stations, and industrial sites needing interim leachate storage before treatment. A 20-5,000 m3 tank buffers collection-truck deliveries or equalizes pH before the main plant. Because leachate is aggressively acidic and ammonia-rich, the FBE barrier's inertness is the reason the tank lasts 30-50 years instead of corroding within seasons.

• Sites: landfill, transfer, industry.
• Use: buffer or equalize.
• Why: inert epoxy barrier.
• Life: 30-50 years.

Specify the leachate pH (often <2), temperature (5-45°C), and COD or ammonia load; set FBE DFT at 250-450 µm cured at 180-220°C. The shell is calculated to AWWA D103-09 and ISO 28765, plates blasted to Sa 2.5, and every panel holiday-tested at 1500 V. Adhesion is verified by ASTM D4541 pull-off.

• pH: often <2.
• Cure: 180-220°C.
• Test: 1500 V per m2.
• Adhesion: ASTM D4541.

An FBE leachate tank resists pH 1-14 corrosion, tolerates impact, and erects fast from bolted panels. The limitation is repair discipline: damaged areas need proper surface prep and touch-up, confirmed during maintenance planning. This boundary is an operating step, because neglect shortens life in the harshest leachate.

• Advantage: pH 1-14, impact-tolerant.
• Advantage: fast bolted build.
• Limitation: needs repair discipline.
• Boundary: confirm touch-up plan.

The figures below are the load-bearing values a supplier should quote per FBE leachate tank; capacities reach 5,000 m3 and design life runs 30-50 years. They let an engineer confirm the shell, coating, and joint system before steel is ordered for a corrosive-duty vessel.

Against GFS enamel and rubber-lined steel, an FBE leachate tank wins on a thick, impact-tolerant epoxy barrier for pH 1-14. Use the table to match the material to leachate chemistry, footprint, and required life.

Send the leachate analysis (pH, COD, ammonia), require the ISO 28765 calculation, the 1500 V holiday test, the FBE DFT log, and ASTM D4541 adhesion. Shijiazhuang Zhengzhong Technology Co., Ltd. (Center Enamel) issues drawings, NDE records, and inspection packages per tank.

• Send: pH, COD, ammonia.
• Require: ISO 28765, 1500 V, ASTM D4541.
• Log: FBE thickness.
• Package: drawings plus NDE.

An FBE leachate tank is a coating-thickness and cure decision first. Specify the 250-450 µm epoxy, the code math, and the adhesion proof, and the tank outlasts bare steel by decades in pH<2 leachate.

A bolted steel tank with Fusion Bonded Epoxy cured at 180-220°C to 250-450 µm, storing acidic landfill leachate (often pH<2) for 30-50 years.

FBE is a thick thermoset epoxy (250-450 µm) with high adhesion; GFS is vitreous enamel fused at 820-930°C. Both resist pH 1-14.

The shell is designed to AWWA D103-09 and ISO 28765, with adhesion verified by ASTM D4541 and plant control under ISO 9001.

Plates are blasted to Sa 2.5, coated to 250-450 µm, holiday-tested at 1500 V, and pull-off tested to ASTM D4541.

FBE resists pH 1-14, covering the most aggressive landfill leachate streams.

Yes. Coating grade, roof, nozzles, and ventilation are engineered per leachate analysis, with drawings issued per tank.

• FBE = 250-450 µm epoxy cured 180-220°C for pH 1-14.
• Resists acidic leachate (often pH<2) for 30-50 years.
• Require ISO 28765, 1500 V test, and ASTM D4541 adhesion.
• Plan touch-up repair to protect the barrier long term.
