What is a Reed Bed?

Oceans ESU Ltd reed beds are highly engineered systems which are planted with Phragmites australis. These reeds have an extensive root system which provides an ideal habitat for natural soil bacteria to thrive. These bacteria are very efficient at degrading a wide range of common chemical pollutants. Oceans-ESU Ltd reed beds are designed and engineered to maximise the treatment efficiency depending on the effluent.

How long does the construction of Reed Beds take?

Depending upon the required application, local environment and location, construction could be as short as two weeks for a reed bed treating small scale industrial effluent, or domestic sewage. Larger projects will take longer, depending on the volumes of water to be treated, and their contaminant loading.

A RIB can be installed in a day, the largest reed beds in the world took 12-16 months to construct, in challenging political and environmental conditions. During the feasibility stage of all projects we will be able to apply our experience from the many varied projects, to provide accurate time scale estimates.

What can Reed Beds treat?

Reed beds are very efficient at treating a wide range of common chemical pollutants and waste water effluents. Examples include hydrocarbons, pesticides, domestic sewage, produced water, composting leachates, fire waters, chemical industry effluents, landfill leachates and many more. Contact us to discuss your requirements.

Why use Reed Beds? (Advantages of Reed Beds)

Reed beds provide environmentally friendly solutions for contaminated waste water problems. As well as providing a valuable wetland habitat for wildlife, they can also be an aesthetically pleasing feature to your development. Furthermore, reed beds are cost effective solutions with very low maintenance requirements (they regenerate naturally!). Oceans-ESULtd has provided waste water remedial treatment systems for many blue chip companies resulting in significant cost savings for the client.

Why are Reeds Beds better than the alternatives?

The majority of waste water treatment systems available utilise four main techniques: Aerobic digestion, anaerobic digestion, ion exchange and filtration. When tailored to a specific source of contamination, the design of reed bed system combines all four of these treatment techniques to produce the optimum treatment method. Soil based reed bed systems encourage bio-reactions to balance the aerobic and anaerobic digestion requirement with chemical absorption and adsorption in a filtering medium.

Reed bed systems are an effective and sustainable method of providing low maintenance solutions to waste water treatment. Once established the reed bed treatment system will require no electricity or chemicals and minimal operation cost. The initial CAPEX costs are equivalent to other treatment systems, provided suitable land area is available.

In addition, a reed bed treatment installation is sympathetic to the environment, aesthetically pleasing and provides an ecological habitat for a wide range of species, in a wetland environment that sustains its own treatment capabilities.

What are the disadvantages of Reed Beds?

There are few disadvantages associated with reed beds as they are cost effective and they can meet or exceed the treatment capabilities of many mechanical alternatives. Reed bed size depends on the volume and chemical composition of the effluent, and so for certain applications a significant amount of land may be required. However, Oceans-ESU Ltd have also developed small modular reed bed systems (RIBs) for sites where space is limited, which can be as small as 3m by 2m. Contact us to discuss solutions for your application.

What is a RIB?

A RIB “Reeds In a Box” is an Oceans-ESU Ltd designed modular reed bed treatment system. It is an ideal solution for small scale effluent problems where space is limited. For larger scale remediation, a number of RIBs can also be installed in series. Typical applications include treatment of small volumes of domestic and industrial waste waters. For example, our RIBs are used on petrol forecourts as an alternative to an interceptor for the treatment of hydrocarbon contamination. The modular nature of the system means that the system is quick to install and larger scale remediation can be achieved using a series of RIBs.

What air/dust monitoring services do you offer?

Typically, air monitoring surveys are used to protect the public and/or employees by ensuring that no one is exposed to harmful levels of dusts and vapour in the air. Oceans-ESU Ltd can offer a wide range of monitoring surveys tailored to meet the needs of each individual client. Assessments are made in line with COSHH (Control of Substances Hazardous to Health) regulations and Workplace Exposure Limits. Our multi-disciplined team includes experienced chemists and toxicologists who make impartial assessments and recommendations for improvement. For further details, see our case studies or contact us.

Can you offer any bespoke monitoring packages to reduce client costs?

By combining our inter-disciplinary approach to environmental projects with our experience of working both in and for diverse industries, we are able to provide suitable solutions tailored to the clients’ needs, whilst maintaining a prudent approach to project spending.

Our senior management team have all held senior positions within industry and are therefore familiar with constraints that the realities of commerce require.

What is a Phase I Contaminated Land Survey (Desktop Study) and why do I need one?

This is usually a requirement of planning permission for a new development. Your local authority may ask that this is carried out to assess the risk that the site may be contaminated. The study involves examining historic maps and environmental databases to determine any past or present land uses which may result in contamination. A preliminary risk assessment and “conceptual model” is also provided – this is a summary of the findings presented in a format which is required by the council.

What happens if contaminated land is suspected?

The preliminary risk assessment contained in the Desktop Study will determine whether the risk of contamination is high enough to require extra work. Should significant contamination be suspected, then it may be necessary to do some further work. For example, this may involve visiting the site to collect soil samples for chemical analysis. This is known as “Phase II Intrusive Investigation” and the outcome is a detailed report including quantitative risk assessment. The outcome of this report will conclude whether or not the actual levels of contamination on the site represent a risk to human health or the environment. If the land contamination is significant, Oceans-ESU Ltd will work with you to develop a suitable remediation strategy to make the site suitable for development. At all stages, we will consult with the local authority on your behalf to ensure that decisions taken meet the requirements of the planning and environmental health departments.

Do I need an ecological survey for development projects?

The need for ecological surveys may arise for many reasons, but often it is required to support a planning application for a development (e.g. change of land use or new development). Surveys are conducted in the context of the project’s immediate footprint and the surrounding area. An expert ecologist will conduct the site survey which involves the examination of the site habitats and surrounding area. A data search will also be conducted for relevant information held by third parties, and a report will be produced to fulfil the requirements of the local authority planning department.
