Containerised Oil-Water Separator

CE Certified / ISO 9001

The RB-C Oil-Water Separator is a fully containerised treatment plant designed for rapid mobilisation to oil & gas fields, refinery sites, marine terminals, and industrial wash-down facilities. Each unit is factory-tested and delivered ready for connection, minimising on-site installation time and cost.

Key Features:

  • API 421 compliant gravity separator design
  • Corrugated plate interceptor (CPI) coalescing media
  • 5-15 ppm oil-in-water outlet achievable
  • Integrated sludge handling and oil collection
  • ATEX Zone 1/2 electrical packages available
  • PLC-controlled operation with remote monitoring
  • 20ft or 40ft ISO shipping container enclosure

Container Constraints & Layout

Every RB-C separator is designed around the physical limits of standard ISO containers while maximising treatment volume and operational access. Internal layout is optimised for operator safety, maintenance clearance, and efficient process flow.

Separator Length 4-10 m

API and CPI separator sections sized to fit within 20ft (6m) or 40ft (12m) container envelopes with end clearance for access and piping.

Coalescer Height Max 1.8 m

CPI coalescing packs and cross-flow media assemblies designed to clear container roof structure while maintaining plate settling area.

Oil Collection 0.5 m Top Section

Dedicated free-oil accumulation zone at the water surface with automatic skimmer and level-controlled transfer to collection drum.

Sludge Zone 0.5 m Bottom Section

Hoppered or sloped bottom with 0.5 m sludge storage depth, timer- or level-controlled progressive cavity pump for automated desludging.

Pumps & Equipment

Feed Pump

Centrifugal cast iron construction with variable frequency drive (VFD) for flow modulation. Handles inlet flow range 5-50 m³/hr with reliable solids passage.

  • Centrifugal cast iron
  • VFD speed control
  • Flow 5-50 m³/hr

Oil Skimmer

Tube or belt type skimmer for continuous automatic oil removal from the separator surface. Discharges to a dedicated oil collection drum for off-site recovery.

  • Tube or belt type
  • Auto oil removal
  • Oil collection drum

Sludge Pump

Progressive cavity pump with bottom suction for reliable sludge withdrawal from the separator hopper. Timer-controlled operation with optional level-based override.

  • Progressive cavity
  • Bottom suction
  • Timer controlled

Piping & Connections

Process Piping

SS 316L or carbon steel process piping rated for oily wastewater service. Inlet and outlet connections DN80-DN150; sludge discharge DN50-DN80. Flanged or Victaulic couplings for rapid site hook-up.

Oil Collection

Collection drum or tank with level sensor and auto transfer pump. Oil phase is continuously skimmed and pumped to storage for recycling or disposal.

Control Panel

The RB-C control system provides fully automated separator operation with local touchscreen interface and remote connectivity options. ATEX-rated enclosures are available for hazardous area installations.

PLC: Siemens S7-1200

Industrial-grade programmable logic controller with expandable I/O. ATEX-option available for Zone 1/2 deployment.

HMI: 7" Touchscreen

Colour touchscreen human-machine interface for local status viewing, alarm management, and manual override control.

Oil Level: Auto Skimmer Control

Capacitive level sensor automatically starts and stops the oil skimmer and transfer pump based on oil layer thickness.

Sludge: Timer or Level Based

Progressive cavity sludge pump activated by programmable timer with optional ultrasonic level switch for demand-based desludging.

ATEX: Zone 1/2 Options

Ex-d or Ex-e control enclosures, intrinsically safe instrument loops, and certified components for hazardous area compliance.

Instrumentation Specification

Parameter Type Range Output
Inlet Flow Electromagnetic 0-50 m³/hr 4-20 mA
Oil Level Capacitive 0-500 mm 4-20 mA
Sludge Level Ultrasonic 0-1 m 4-20 mA
Oil-in-Water UV Fluorescence 0-30 ppm 4-20 mA
