NEWS MPs back Buddying
CIWEM has received an overwhelm- ing response to its Buddying scheme, where MPs were invited to be paired with a local CIWEM mem- ber. Partnerships are expected to allow the MP to have a local contact for regional environmental issues, it will also allow CIWEM to build a rela- tionship with an interested MP.
Several queries have already been received ranging from river restora- tion to high speed rail and partner- ships have already been established which CIWEM hopes to build upon over the next year. Other benefits to MPs include
briefing material for debates and invi- tations to CIWEM events.
Cuts ‘put geo-data at risk’
A survey of specialists in geographic data indicates that public and private sector cuts could have a knock on impact on the quality and accuracy of digital data, used to map environ- mental risks and inform planning and risk management. Geo-data is used in engineering, emergency services planning, envi- ronmental protection and risk man- agement systems, transport plan-
ning, and development control and planning. In
a survey by the
Association for Geographic Information (AGI) and Price-waterhouseCoopers LLP, in which over 100 public and pri- vate sector organisations were polled, 96% saw geographic information as a business enabler. Seventy-three per cent of those
asked believe better use of data in the next 12 months is imperative.
Correction CSO Technik is Lackeby Water’s sole UK distributors for its range of Rotosieve drum screens and heat exchangers, consequently the arrangement is one of principal-distributor. CSO Technik is not owned by Lackeby Water, as stated in WWT (July, page 11).
Moving on up
Infrastructure contractor Barhale Construction has appointed Mark Cutler as chief executive. He joins from Morgan Est where he was managing director. Cutler has direct experience in all Barhale’s operating sectors, including water, transport and energy.
Grundfos Pumps has appointed Nick Christopher as area sales manager with responsibility for the industry, water and wastewater distribution network in East Anglia, Midlands and Yorkshire.
Biwater Treatment has recruited Joanne Startin as performance manager. Startin was previously responsible for change and performance management at United Utilities.
Partech Instruments has announced the appointment of Derek Bourne to the position of director of export sales & marketing. Formally with Siemens Water Technology, his appointment will strengthen the Company’s plans to become a leading player in the international market.
INDUSTRY VIEW
Greg Turner, Technical director,
Landfill is one of the most common methods used to deal with municipal and industrial waste in the UK and rainwater plays an essential role to biodegrading the organic matter an open landfill contains. However, as the rainwater filters through the landfill it becomes contaminated, and creates an effluent called leachate. This leachate may contain toxins capable of having a chronic impact on the environment, including a considerable reduction in bio-diversity. This is why local authorities have put stringent requirements in place for the treatment of leachate before its release to sewer or open water course.
The Candles landfill site in Shropshire is managed by Veolia Environmental Services. In 2000, they asked Veolia Water to manage the leachate and build a new treatment plant. The aim was to remove contaminants and harmful chemicals commonly found in leachate; and also find ways to lower the overall environmental impact and carbon footprint of the plant.
Sustainable processes
Over the past decade, the team has developed an extremely innovative and successful solution that implements many new sustainable processes and technologies, for example: • Biogas extracted from the landfill that used to be burnt off, is now used to generate electrical power, which is exported to the National Grid
• Heat is taken from the exhaust gases (at 950kw per hour and at 450-500ºC) into two waste heat boilers that generate a tonne of steam at six atmospheres (six bar pressure). The steam is then used to power the ammonia distillation process • The ammonia produced is then concentrated to 12% wastewater for export from site for NOX suppression in flue gas discharges • The distilled ammonia solution is then sold commercially – another sustainability ‘plus point’, as the ammonia purchased would otherwise have been taken from natural resources.
In addition, the plant’s operational costs were benchmarked against the market price for tankering leachate offsite for disposal at licensed facilities. The results proved that the new approaches aren’t only the most environmentally friendly option; but they make good economic sense too. As far as we are aware, this is a UK first in terms of the application of this technology. I’m confident that the installation developed at the Candles plant can be easily replicated for many other industrial processes requiring this type of separation technology… which is especially good news for the UK water industry, and the environment.
