Featured Case Studies


Hydrocarbon Removal from Oilfield Produced Water: Heglig, Sudan

In 2003, Oceans-EWS partner, UK based Oceans-ESU Ltd, was commissioned by GNPOC to undertake the construction, management and maintenance of reed beds in Heglig, Sudan. The reed beds function as a means to clean produced water by biological treatment removing oil contamination.


Contaminated Water Solutions: Billingham, UK

The 1930s saw the merger of four local chemical companies to form the industrial giant, Imperial Chemical Industries (ICI). Billingham chemical plant grew to become a multi function organic and fine chemicals production unit. In 1986, when Oceans-ESU Ltd were contacted, ICI had 250 batch manufacturing units spread over 650 hectares.


Remediation: Llanwern Steelworks, UK

Llanwern Steelworks (formerly the Spencer Works) is located in Llanwern, east of the City of Newport, South Wales. Built by Richard Thomas & Baldwin Ltd, the works was originally referred to locally as “The RTB”, before being called Spencer Works and later Llanwern.

The Technology

MSR-Technology™ “Microbial-Soil-Reed Beds” is providing world-leading treatment of industrial wastewaters including hydrocarbons from numerous producing oil fields. All stable processes for treatment of organic contaminants involve the degradation of common and complex compounds with the use of microbial action in either anaerobic or aerobic conditions. Organic wastes provide nutrient for microbial growth.
