Domestic Sewage Treatment Plant Oil Interceptor for Workshops and Fuel Sites
Oily wastewater from workshops, fuel stations, and wash areas can contaminate drainage systems and lead to compliance risks. A domestic sewage treatment plant integrated with an interceptor captures oil, grease, and solids before discharge.
Built for domestic sewage treatment plants, our oil interceptor offers advanced oil-water separation, ensuring clean discharge for workshops and fuel sites. The Oil Interceptor system includes gravity, coalescing, bypass, full-retention, and above-ground configurations for varied site needs.
At Dutco Tennant LLC, high-quality interceptor solutions are supplied for contractors and project requirements across the UAE and GCC, including the industrial Oil Interceptor range for demanding environments.
Efficient Separation for Cleaner Discharge
- Multi-compartment baffle design slows flow, allowing sediment and grit to settle before separation
- Coalescing media merges fine oil droplets for faster surface separation
- Built-in storage retains hydrocarbons, preventing carryover during peak flow
- Access risers allow easy sludge and oil removal without confined entry
- Non-return outlet valves prevent backflow during surge conditions
Core Technical Capabilities
- Separation Efficiency: Gravity and coalescing plate units achieve effluent oil concentrations below 100 ppm; coalescing media units achieve below 5 ppm under normal operating conditions
- Construction Materials: Precast concrete, GRP fibreglass, and mild steel with epoxy lining for below-ground installations; stainless steel AISI 304 and 316 for above-ground and corrosive exposure applications
- Flow Configurations: Full-retention and bypass configurations available — full-retention treats all incoming flow; bypass diverts peak storm flows above the rated treatment capacity around the unit
- Inlet and Outlet: Compatible with standard PVC, HDPE, and concrete drainage pipe networks with flexible coupling connections accommodating misalignment and minor differential settlement
- Compliance: Units comply with EN 858-1 and EN 858-2, BS EN 858, and regional municipal drainage authority requirements for hydrocarbon discharge from commercial and industrial premises
Types
