Imtech wins £75m Thames Water project for digestion of waste water sludge

April 4th, 2013 by nwp

Technical services provider Imtech, as part of the Tamesis team – a joint venture between Laing O’Rourke and Imtech Water, Waste & Energy – has been awarded a £75 million contract by Thames Water to develop two Advanced Digestion plants at wwtp Crossness and wwtp Beckton in London.

By advanced anaerobic digestion of sewage sludge, it is possible to convert the sludge into biogas, contributing both environmentally and financially.

Thermal hydrolysis
This substantial investment is part of the Thames Water Sludge Strategy. The strategy has been developed to include a number of anaerobic digestion plants at sludge treatment centre’s in South East England.

The project comprises the design, construction, commissioning and optimisation of two new advanced digestion plants, including two-stream Thermal Hydrolysis plants. Thermal hydrolysis is a process that uses elevated pressures and temperatures to increase cell breakdown and increase biogas yield.

One of Europe’s biggest waste water treatment plants
The two-year investment programme is situated on two of the largest sewage treatment works (STW) in the UK. Beckton STW is one of Europe’s biggest waste water treatment plant and serves a population of over 3 million. Crossness serves over 1.8 million.

When completed each THP plant will provide sludge treatment capacity for approximately 42,000tds/year (tds = totally dissolved solids) to treat indigenous sludge from the sites.

Joint venture Imtech and Laing O’Rourke
Commented Bruno Speed, Managing Director at Imtech Water, Waste & Energy: ‘This is a major contract for the Tamesis team and we are delighted that it has been awarded to us. Tamesis is already upgrading the STWs at Crossness and Beckton, so we are well versed with the existing sites. The joint capabilities of Imtech and Laing O’Rourke mean that we are perfectly positioned to undertake such a prestigious project.

Advanced AD is an important step forward for Thames Water, helping the business to become more sustainable and move towards power self-sufficient wastewater treatment.’

HKV Consultants to study road use for flood evacuation East Midlands

January 13th, 2013 by nwp

HKV Consultants, together with HR Wallingford and the Institute of Transport Studies (University of Leeds), will study the effective use of roads in Lincolnshire and Norfolk to evacuate or shelter people.

This study is commissioned by the Government Office for the East Midlands.

Highest flood risk in the UK
The East coast of England, due to its geographical location, faces a particular hazard from a storm surge in the North Sea, such as occurred in January 1953. Combines with a low-lying nature of much of the land bordering the Wash, this means that the countries of Lincolnshire and Norfolk have some of the highest flood risk in the country.

Options for evacuation
There is a particular concern that Lincolnshire and Norfolk would be both badly affected by a major surge flood and would find it difficult to both move people out and move equipment in. Therefore a better understanding is required about the options for evacuation and the key parameters of such evacuation.


The Great Flood along the coast of Lincolnshire (Acre Gap in Sandilands) on 31 January 1953 after a tidal surge of 5.6 m above average sea level.

South West Water selects PWN Technologies’ Six/CeraMac technology for pilot project

October 5th, 2012 by nwp

South West Water, the water utility in the Southwest of England, has signed an agreement with PWN Technologies on October 2nd, for the delivery of a Six/CeraMac pilot facility.

This facility will be commissioned in February 2013 and will be intensively tested over a 18 months period.

South West Water will examine the innovative and sustainable SIX/CeraMac technology in a detailed piloting.

Robust and compact treatment process
Chris Rockey, Science and Water Quality manager South West Water (l): “The Six/CeraMac process has been selected for detailed piloting as we believe it will provide a robust and compact treatment process producing excellent quality drinking water now and in an uncertain future.”

South West Water expects that the collaboration with PWN Technologies can help to continue to provide their customers with good, safe drinking water they can trust as efficiently as possible, whilst minimizing the impact on the local (and global) environment.

First European Partner
Jonathan Clement, Director of Technology Application of PWN Technologies (r): “We are very pleased that South West Water — as our first European partner — has chosen our sustainable and cost-effective Six and CeraMac solutions. This is another major acknowledgement for this award-winning technologies. We are looking forward to working closely together with the South West Water-team.”

Full scale pre treatment in Anijk, the Netherlands
PWN Technologies is involved in the construction of a full-scale pre-treatment installation based on SIX (Suspended Ion eXchange) and CeraMac in Andijk, the Netherlands, that will become operational end 2013.This new treatment process will produce water of a better quality, but will also have a lower energy consumption (30%) and lower environmental load (using a natural resin instead of ferric chloride sulfate).

Minimizing set-up and operating costs
CeraMac is an innovative block design that marks a new era in the application of ceramic membranes in treatment for drinking water. The key design feature of CeraMac is that rather than having ceramic membrane modules in individual stainless steel casings, up to 200 ceramic elements can now be housed in a single stainless steel vessel.

With a significant reduction in materials usage and plant size, this sustainable innovation minimises the set-up and operating costs of using ceramic membranes to a level that is cost-competitive with legacy polymeric membranes.

Grontmij delivers energy scheme for Yorkshire Water’s new thermal hydrolysis sludge plant

December 9th, 2011 by nwp

A joint venture between Grontmij and UK company Morgan Sindall, has been appointed to deliver a pioneering energy scheme worth over 1.5 million euro over two years for Grontmij.

High pressure thermal hydrolysis
Yorkshire Water manages the collection, treatment and distribution of water in the Yorkshire district. At its waste water treatment plant Esholt (750,000 pollution equivalents) in the Leeds and Bradford area, the company is building Britain’s first fully operational thermal hydroloysis plant for sludge treatment.

The Thermal Hydrolysis Process (THP) is based on enzymic hydrolysis and high-pressure thermal hydrolysis (10 bar). This process not only produces significantly more biogas but is set to show how it makes digesters easier to manage and less costly to operate.

Saving millions of pounds
The assignment of Grontmij is to design the energy scheme for the thermal hydrolysis plant which will save the utility company millions of British pounds a year in electricity consumption and expenditure.

Fully self-sufficient wwtp
In 2010/11, use of its own renewable energy sources produced around 10% of the company’s electricity needs. It aims to increase this figure to around 15% by the end of 2014/15, and to more than 20% by 2020. Ultimately, the waste water treatment works will be 100% self-sufficient in energy production making it by far the greenest plant.

British queen ‘goes green’ with Dutch Landy hydro power screw

September 23rd, 2011 by nwp

The 40-tonne Archimedes’ screws were put in place early September by crane at Romney Weir on the River Thames, just a few miles from Queen Elizabeth’s favourite royal residence Windsor Castle.

Water sets screw in motion
The turbines are made by the Dutch watertechnology company Landustrie. The LANDY hydro power screws are installed in a small overflow dam of the Thames where they will generate energy. The water that flows downstream sets the screw in motion and so generates ‘green’ electricity for local use. It is estimated the turbines will reduce carbon dioxide emissions by 790,000 kilos per year.

Leasing the dam
The Archimedes Screw turbines, supplied to the Windsor Castle by Southeast Power Engineering Ltd, will be ready to operate from November. The company is working in partnership with the Environment Agency, which is leasing the weir.

Large potential for green energy
The Environment Agency sees the many small dams in the UK as untapped source of energy and is keen to ensure hydropower fulfils its potential as a small but useful renewable energy source, whilst protecting the environment.

In Berkshire, the agency teamed up with Windsor and Maidenhead council to investigate schemes at Marlow, Boveney and Boulters weirs, while work is already under way to generate electricity at Osney and Goring weirs in Oxfordshire.

The small dams were originally built to control water levels for navigation and flood risk purposes.

Eastern Scheldt estuary home to innovative tidal stream project

July 26th, 2011 by nwp

The international business consortium Clearwater has been given approval by the Dutch government to proceed with the preparations of an innovative tidal stream energy generation project. The Clearwater project aims to generate energy from lower velocity tidal streams in the Eastern Scheldt estuary.

Low tidal velocities
According to the consortium the tidal energy project is remarkable, because it will generate energy from lower tidal velocities and consistent currents, something that was not possible in an efficient and cost effective manner up until now. Normally, tidal turbines are applied in areas with strong tidal currents.

The Clearwater Project combines Atlantis Resources Corporation’s technology with the specialised Dutch engineering skills, experience and know-how of Ballast Nedam, Delta Energy, IHC Merwede and Royal Haskoning.

Breakthrough in delta areas
It is estimated that with the consortium’s initiative, 50% of the total economically exploitable free stream energy in The Netherlands is secured. This breakthrough accomplishment can open up the potential for tidal stream energy in Delta’s around the world with similar conditions, in particular where access to conventional energy is a problem.

Export boost
The Clearwater initiative was proposed as a business case to Top Team Water, who in a bid to boost export of the Dutch Water Sector, invited the Netherlands’ leading industry members, research and government institutes to submit business cases that would strengthen the sector’s export base.

Innovative business cases
Selected business cases were put forward to the Dutch Government’s Ministry of Economic Affairs (Minister Verhagen) for immediate implementation in the Netherlands on 17 June 2011, with the Top Team adding momentum and support in order to shape the right conditions for swift implementation. The Clearwater initiative is in line with the ambition of the Zeeland Province to become the Water Energy Valley.

The Clearwater consortium consists of Zeeland’s utility company Delta Energy, IHC Merwede, Ballast Nedam, Royal Haskoning and Atlantis Resources Corporation.

Atlantis Resources Corporation placed its first AK1000 tidal turbine off the Scottisch coast near Orkney in September 2010. Atlantis Resources claims the AK1000 to be the most powerful tidal turbine in the world.
