Case Studies

Environmental management solutions developed by Oceans-ESU Ltd have been used for a wide range of applications to benefit organisations all over the world.  Here are just some examples of the challenges we have overcome for our clients and the benefits our solutions can bring. If you would like to discuss any of these projects or any related issues please contact us.

Reed Beds

Reed Bed Holding and Filtration for Maltings
Oceans ESU were approached by a maltings company to provide a solution for the treatment of steep water effluent.

Treatment of High Strength Waste from the Food Industry
Oceans-ESU Ltd have developed the use of reed bed technology to treat high strength wastes from the food industry, namely in the yeast manufacturing sector, and also with success in the starch manufacturing sector.

Game Conservation Reed Bed for Domestic Waste
In November 2013 Oceans ESU Ltd were commissioned by a UK game conservation charity to refurbish a horizontal flow gravel based reed bed. The bed is designed to treat sewage effluent from 8 properties within the area.

Groundwater Remediation – Shale Oil Refinery, Pumpherston
Oceans-ESU Ltd designed and constructed a reed bed treatment system to remediate the groundwater at a former shale oil refinery and detergents manufacturing facility at Pumpherston.

Treatment of Effluent Containing Ammonia and Phenol Derivatives, Llanwern
Llanwern Steelworks was the first oxygen-blown integrated steel works in Britain when it opened in 1962. In 1986, Professor Lucian Gill was contacted by British Steel who were looking for a way to dispose of the wastewater effluent produced on site.

Coke Oven Wastewater Remediation, Whyalla
The Whyalla steelworks is located South Australia, approximately 400km North of Adelaide. In Australia, reed beds have been used for storm-water run-off and sewage treatment, but little was known about applications to steelworks wastewater treatment.

Recycling Facility Waste Water
Oceans-ESU Ltd were commissioned to design and install a waste water remediation system for a materials recycling facility.

Reed Bed Treatment of Amine/Phenol Wastewater, Billingham
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, the ICI had 250 batch manufacturing units spread over 650 hectares. This made it the largest integrated facility at the time in Europe. They were looking for a way to dispose of the wastewater effluent produced on site.

Produced Water Bioremediation with Beneficial Reuse
Commissioned by PDO, Oman, Oceans-ESU/Danish Rootzone designed and constructed the world’s first dedicated application of reed beds to produced water. This produced water treatment system was designed with the inclusion of onward design for forestry and agriculture to establish the concept of beneficial reuse.

Sewage and Petrol Station Runoff, BP Raunds
The BP development at Raunds is believed to be the most environmentally friendly service station in the UK! Oceans-ESU Ltd designed a reed bed system that treats all the foul drainage and hydrocarbon-contaminated surface run-off, while ensuring safe operation of the facilities in terms of odour and contamination risk. The treated water is discharged into a stream.

Reed Bed Remediation of Landfill Leachate, Dumfries
In 2004 Dumfries & Galloway Council commissioned Oceans-ESU Ltd to provide an innovative remedial solution to the problem posed by leachate from a capped landfill site.

Airport Fire Training Effluent Treatment, Humberside
Airports typically have their own fire and rescue service, and often have a training area on site where they can practice various fire fighting scenarios. The water resulting from the training is generally contaminated with partially burnt fuels, and fire fighting foams. The foam is of particular concern, due to the environmental persistence of some of the components, such as fluorosurfactants including PFOS.

Reed Bed Treatment of Municipal Sewage, Turlinjah
Turlinjah is a small community of 70 people on the NSW South coast of Australia. Previously sewage was collected in septic tanks located less than 200 meters from extensive oyster leases in the Tuross Lake. There was concern about the untreated septic discharge into this sensitive receiving environment.

Pesticide Contaminated Soil & Groundwater, Wheathampstead
Oceans-ESU Ltd were asked to remediate an old industrial site in South East England. The site was formerly a pesticide research and development factory which had been a manufacturing base for a wide range of agricultural, horticultural and garden chemical products.

Secondary Sewage Treatment, Tufton
Oceans-ESU Ltd were asked to design and install a reed bed system to provide treatment of sewage from a Christian retreat in the South East. The retreat is located in a rural setting and is not connected to the mains sewer. The client was looking for a low cost and environmentally friendly solution which was in keeping with the location

Hydrocarbon Removal from Oilfield Produced Water, Sudan
In 2003, Oceans-ESU Ltd was commissioned by GNPOC to undertake the construction, management and maintenance of reed beds in Heglig, Sudan. The reed bed functions as a means to clean produced water by removing oil contamination.

Reeds in a Box – Smart Award
Oceans-ESU Ltd won a ‘Smart’ Award in 1998 to develop a new reed bed technology for treating hydrocarbon-contaminated wastewater from petrol station forecourts. In 1999, we were awarded a second Smart Innovation Grant to partially fund an ambitious £300,000 development project to develop the prototype Reeds in a Box (RIB) to a marketable stage.

Land Remediation

Acidic Landfill Leachate Remediation, Tanfield Lea
Oceans-ESU Ltd were commissioned to identify solutions for large consistent volumes of landfill leachate emanating from a restored landfill site. The landfill had been used for many years, for the disposal of domestic and vehicle batteries and it was believed other wastes were also tipped. This leachate posed a threat to local surface and groundwaters.

Chlorinated Solvents Groundwater Cleanup, Hitchin
Oceans-ESU Ltd was called in to advise upon the clean-up of a site affected by chlorinated solvents. The site was a former tannery, and had been derelict for a number of years. The ground was very porous, with an important chalk aquifer beneath. These conditions left the groundwater vulnerable to soil contamination.

Remediation Project Management, Braehead
Oceans-ESU Ltd led the remediation of a massive multiphase development of old industrial land on the south bank of the River Clyde. 100 hectares of land were being developed for leisure and commercial use by Capital Shopping Centres in Glasgow. Oceans-ESU Ltd has been involved since the onset of the project in 1994.

Methane Protection Systems
In the early 1990s a major UK retailer approached Oceans-ESU Ltd requiring a land contamination and methane gas investigation, for a number of its stores. This resulted in Oceans-ESU Ltd designing one of the first ‘retrofitted’ methane protection systems in the country

Asbestos Project Management
Oceans-ESU Ltd were appointed as Asbestos Project Managers for an internationally recognised company that has over 450 retail outlets throughout the United Kingdom.

Monitoring for Nuisance Dust at a Recycling Site
Oceans ESU were approached by a recycling company who required an assessment of dust generated on their site, in order to determine any impact of their operations on surrounding properties.




Environmental Impact Assessment
Oceans-ESU Ltd carried out a Baseline Environmental Impact Assessment to establish the impacts of the installation of a reed bed treatment system in Heglig, Sudan.

Control of Major Accident Hazards (COMAH) Assessments
Oceans-ESU Ltd undertook a COMAH assessment for a chemical storage facility in Glasgow .
