Development of a safe, compact, highly efficient, economic and fully automatic electrolytic treatment system for separation of emulsified oil from wastewater of ships (bilge) and oil rigs (slop)
The OilEClear consortium aims to develop a treatment system for oily wastewater at ships and oil rigs, enabling these to meet current and future bilge and slop water regulations with regard to oil hydrocarbons (THC), dissolved organics and toxic metals. With the currently available treatment technologies, it is a great challenge for the ship and rig operators to meet the regulations regarding discharge of oily wastewater. A huge market is therefore open for better alternatives. The OilEClear project aims at a new, patentable electro-coagulation treatment system, meeting a THC standard of 5 ppm which also removes organics and toxic metals. The system will separate emulsified oil from water by use of a novel three-phase separator design. Effluent data and operation will be integrated with process control by use of ultrasound measurement of flow and particles and automatic logging and monitoring of THC by UV-fluorescence.
