REED BED TECHNOLOGY PROVIDERSReed Beds are a natural way of treating contaminated water. The pollutants are decomposed by the actions of bacteria and other microbes living within the soil.

The reeds provide the soil structure and the habitat for microbes to thrive amongst the plant roots.

04 05

We specialise in soil based reed beds

which offer much better treatment

capabilities than gravel based systems,

and they have the added advantage that

they don’t need periodic digging out

and replacement like many gravel based

constructed wetlands do.

Soil based reed beds are very versatile

and can be used to treat a wide range

of different pollutants and waste waters.

They can be designed to work in

different climates and to solve waste

water problems of different scales. For

example, small containerised systems

treating waste water from a single house,

to large scale systems for oil fields

treating more than 50 million litres of

contaminated water per day!

Not only are reed beds an environmentally friendly solution, they can be very cost effective too.

Often, they can be designed to be

entirely passive systems, operating by

gravity with no mechanical or electrical

parts. This means operational costs are

minimal, and they only require basic

horticultural care to ensure they continue

to achieve the relevant water quality

requirements.

CASE STUDY 1 GNPOC, Sudan

We were engaged by GNPOC in 2002 to provide consultancy for the treatment of oilfield produced water, contaminated with hydrocarbons based compounds and heavy metals. A pilot system was implemented and achieved approval from the Sudanese government (Ministry of Energy and Mining) in 2005, whereby the treatment methodology and its implementation under our authority was recommended by the government for extension to cover all water treatment within the Sudanese Oil Fields.

Attached is a copy of the letter from the Sudanese government confirming approval.

In 2007 a further 8 produced water treatment systems were designed by and constructed under our supervision. This represented a total investment of US$100m by GNPOC and their shareholders.

The pride taken by the GNPOC shareholders in the success of the work undertaken by us is highlighted by the use of the project as a case study within multiple group wide reports published by the Petronas Group. 

Attached is an extract from Petronas Sustainability Report, 2009 (page 23).

Attached is an extract from Nada (Corporate Newsletter of the Petronas Group), Q3 2009 (pages 18, 19 & 20).

In 2010, Sir Mark Moody-Stuart (ex-Chairman of Royal Dutch/Shell Group) acting in the capacity of Chairman for the United Nations Global Compact group visited the Heglig oilfield within the GNPOC concession. His summary letter complimented GNPOC and Oceans-ESU on the standard of their work

CASE STUDY 2 DPOC/WNPOC/PDOC/GPOC/SPOC, Sudan & South Sudan

Following the recommendation from the Ministry of Energy and Mining (Government of Sudan) that the produced water treatment technology implemented by us be extended to all Sudanese oilfields, we were engaged as consultants by White Nile Petroleum Operating Company (WNPOC) and Petrodar Operating Company (PDOC).

During the period of 2007 to 2010, three reed bed treatment systems were designed by and constructed under our supervision within the PDOC concessions. Within the WNPOC concession, one reed bed treatment systems was designed by and constructed under the our supervision during the period of 2008 to 2009.

Following construction, we were contracted to operate, monitor and maintain the treatment systems as consultants to WNPOC and PDOC.

Following the cessation of South Sudan from the Republic of Sudan in 2011, the oilfields of Sudan were split. As a consequence the oilfield operators (GNPOC, WNPOC and PDOC) were required to divide their structure across the border, in effect giving birth to 3 South Sudanese oilfield operators (DPOC, GPOC, and SPOC respectively).

We were engaged as environmental consultants to the three new companies, primarily for the management and treatment of oilfield produced water, whilst remaining contracted as environmental consultants to the three North Sudan based operators.

Attached are a series of letters from the oilfield operating companies providing reference for the consultancy works undertaken by Oceans-ESU.

CASE STUDY 3 Petronas

Following the success of the produced water treatment systems in Sudan and South Sudan, of which Petronas were a major shareholder in each of the oilfield producing companies, Petronas engaged us to provide consultancy to the Petronas Group within Malaysia.

In 2008 we provided an educational programme to the Central Technical Services Department based at Petronas headquarters in Kuala Lumpur so as to educate CTSD team on remediation techniques and technologies that we had successfully implemented in Sudan and on other projects. The scope was devised so as to enable CTSD and ourselves to identify and deliver sustainable remediation projects throughout the Petronas Group. Following a successful delivery of the educational programme, a feasibility study was undertaken across numerous sites to identify the sites of particular concern and produce a roadmap to implement improvement and/or remediation strategies.

In 2010 we and CTSD worked in collaboration to remediate an oil sludge farm heavily contaminated with hydrocarbons and heavy metals.

In 2012 we were engaged by CTSD and Petronas Chemical Fertiliser Kedah (PCFK) to design, build and establish a treatment system for the treatment of wastewater produced as a by-product of fertiliser production. In 2016 the system successfully passed its final chemical performance test and we are still providing ongoing consultancy services for the system which is still in full operation.

In 2013 we were contracted by CTSD and Petronas Vinyl Chloride Malaysia (VCM) to remediate groundwater, contaminated with 1,2-dichloroethylene and vinyl chloride, found beneath the VCM site that was undergoing deconstruction. Works included initial groundwater and contamination modelling as well as the design, construction supervision and establishment of the extraction, treatment and reinjection systems.

In 2016 the project passed its final performance tests and it continues to passively remediate the groundwater.

Attached is a letter from Alias bin Mamat, Head of Plant for VCM, outlining his positive experience working with Oceans-ESU. In 2014 the VCM groundwater treatment project was highly commended by the Institute of Chemical Engineers (iChemE) Awards.

CASE STUDY 4 Sainsbury’s, UK

Sainsbury’s is widely accepted as one of the ‘big four’ supermarket retailers in the UK.

From 1986 to 2005 we were engaged by Sainsbury’s to assist and provide consultancy to Sainbury’s for remediation of sites owned by Sainsbury’s, so as to allow for the future development of the contaminated sites.We had responsibility remediation and clean-up of 450 sites across the UK as the lead Environmental Consultant to Sainsbury’s. As part of the works we designed and implemented an environmental risk management database so as to allow efficient and effective management of the contaminated sites by Sainsbury’s.

After successful remediation of the portfolio of contaminated sites owned by Sainsbury’s, our direct consultancy to Sainsbury’s ended.

CASE STUDY 5 Braehead Development Consortium, UK

Following the success working with Sainsbury’s as their lead Environmental Consultant, we were recommended by Sainsbury’s to the Braehead Development Consortium in Glasgow. The Braehead Development Consortium was a consortium of UK retail giants, including Sainsbury’s and Marks & Spencer, tasked with the re-development of 100 hectares of old industrial land on the South bank of the River Clyde in Glasgow.

We were first contracted in 1994 to undertake the site investigation and make recommendations for the area designated for development of leisure and retail by Capital Shopping Centres. In 1995 we were re-engaged to carry out the recommendations for land and soil remediation, culminating in the successful development of the land for the Braehead shopping and leisure centre. We have since been repeatedly contracted to continue the remediation of the wider 100 hectare site to allow for development of housing and other commercial developments.

In 2016 we completed the last remediation validation for the 100 hectare site, allowing the last phase of housing developments to be successfully implemented.

CASE STUDY 6 Combining Heavy Metal And Sewage Filtration

Soil based reed beds are very versatile and can be used to treat very different effluent types in a combined system.

In 2003, Oceans-ESU Ltd were asked to provide a water treatment system for a paper recycling facility. The client had two waste waters to treat: wheel wash water which was contaminated with a range of heavy metals; and effluent from a sewage package plant.

Oceans-ESU Ltd designed a combined system. The wheel wash water is passed through 4 containerised soil reed beds (RiBs, or Reeds in a Box), which contain a specific soil blend designed to entrap the metals.The water then passes to a standard two stage soil based reed bed where is it joined by the sewage effluent. This phase is designed to breakdown organics, reducing COD, BOD and ammonia to meet the relevant discharge criteria.

The 4 containerised reed beds are designed so that the media can be dug out and replenished periodically (in this case every 3-5 years) to remove the heavy metals from the system. This represents low operating cost for the client as the cost of waste disposal is reduced to a few tonnes of soil every few years eliminating the need to pay to dispose of the daily influx of metal contaminated water.

The organic treatment reed beds do not need refurbishment and are still successfully treating the water 15 years on.

CASE STUDY 7 Treating mixed waste waters for more than 20 years

Billingham reed beds were designed and built by Oceans-ESU Ltd in 1990 to treat mixed waste waters from ICI, then the largest chemical facility of its type in Europe.

The waste water was highly contaminated with amines and phenols (COD up to 5000mg/l). The facility used a batch processing method, which meant the water was highly variable, and very difficult to treat by conventional methods.

Oceans-ESU Ltd demonstrated that soil based reed beds were the ideal solution as they were versatile enough to handle the variation and mix of contamination, they could accommodate shock loadings and they could even adapt to different waste water types.

The resulting system consists of 7 reed beds totalling 5 hectares in area with a treatment capacity of up to 3,000m3 of water per day.After many years of successful water treatment, the facility closed and the reed beds proved invaluable during this time as they provided treatment for all the washdown waters created during the decommissioning process.

Today, the site is owned by a waste management company who continue to use the reed beds for the treatment of tankered liquid waste (landfill leachates and gully waters).

The system has since received two prestigious awards: a LARAC award for “Best New Idea” and CIWM’s “Innovation in Waste Management and Resource Recovery”.
