Key Features
- Fiberglass Construction: Superior corrosion and chemical resistance (resists over 1000 chemical combinations up to ~148 °C).
- Lightweight Design: Roughly 1/3 the weight of a comparable steel tank, reducing handling and foundation needs.
- Dimensional Stability: FRP does not expand, contract or crack under thermal cycling, unlike concrete or metal.
- Maintenance-Free: Gel-coated, corrosion-proof interior requires no repainting or internal coating.
- Double-Wall Options: Available with secondary containment and interstitial leak detection for maximum environmental safety.
- Instrumentation-Ready: Pre-fitted with provisions for automatic level sensors, radar floats and leak-alarm connections.
- Standards Compliance: Engineered to meet BS EN 858 (Oil/Water separators) and other regional regulations for effluent quality.
Benefits
- Long Service Life: FRP separators last decades with no internal corrosion (service life ~30 years).
- Installation Ease: Delivered as a finished module (often flat-packed) that can be set in place with minimal site work.
- Reliability: Consistent oil/water separation performance with no deterioration or clogging of fiberglass walls.
- Cost Reduction: Lower weight and no need for protective coatings reduce overall project cost.
- Environmental Safety: Double-wall models and electronics provide early leak detection, safeguarding soil/groundwater.
- Regulatory Compliance: Designed to achieve effluent oil concentrations <5 mg/L as required by many environmental agencies.
Applications
- Petroleum Refineries & Terminals: Stormwater drains, spill capture and wastewater treatment (harbors, loading racks).
- Oil & Gas Production: Well-pad and pipeline run-off separators at oil fields and gas processing plants.
- Marine & Shipping: Bilge-water separators on vessels, jetty effluent treatment at marine oil terminals.
- Power Generation: Cooling tower blowdown and drainage systems in power plants and gas turbines.
- Manufacturing & Automotive: Machine sump and washout water treatment in metalworking and automotive plants.
- Airport & Highway Runoff: Roadway and runway runoff interceptors to capture fuel/grease before discharge.
- Chemical Plants: Pre-treatment for oily wastewater streams before biological or clarifier processes.
Technical Specifications
- Capacity Range: From a few hundred to tens of thousands of gallons (e.g. 600 USG up to 50,000 USG tank volume).
- Flow Rate: Handles influent flows from zero up to ~4,000 USG/min (252 L/s).
- Construction Method: Hand-layup or filament-wound FRP with corrosion-resistant gelcoat.
- Separator Type: Parallel-flow gravity units with coalescing baffles, lamella packs or plate separators as required.
- Monitoring: Optional radar level transmitters, electronic oil-level alarms and leak detectors included.
- Standards: Designs comply with BS EN 858-1/2, ASTM D3299 or equivalent.
Unique Selling Points (USPs)
- Extremely Corrosion-Resistant: Unaffected by petroleum, solvents or most chemicals – no lining or coating needed.
- Ultra-Lightweight Delivery: FRP separators can be shipped as finished tanks on a single truck and craned into place, speeding up construction.
- Double-Wall Safety: Underground models include a secondary FRP shell and monitoring fluid for leak detection (best practice in oil & gas).
- Built-In Quality: Each tank is factory-tested for leaks and structural integrity, ensuring a reliable fit-out with instant water-tightness.
- Long-Term Value: Designed for a 30+ year life with virtually no structural maintenance, far exceeding the life of steel or concrete alternatives.
- Turnkey Solution: We supply complete separators with piping, valves and controls as needed for plug-and-play installation.
