Controlling corrosion in desalination plants
Over the past ten years, Desalination and Reverse Osmosis (RO) systems have come into their own as an excellent alternative to treating drinking water, particularly in areas which have either a shortage of natural ground/surface water or are near seawater supplies. However, there are problems associated with producing such high quality drinking water.
Bio-test monitors benzene emissions
Chemical exposure has been a growing concern for over forty years. Although emission controls have improved considerably, demands for higher quality industrial and municipal life create a need for more comprehensive methods of chemical exposure measurement. Until now regulatory agencies have had to be satisfied with measuring concentrations of polluting agents in the environment around the exposed worker or citizen. However, as our understanding of the complex effects of exposure advances, so the demands for evaluating an individual's actual exposure increase.
Energy management steps forward
Energy management was last a big issue in the 1970s. Since then, the impetus has not been maintained and energy demands per employee have risen. Now many organisations are beginning to tackle their energy issues, but not in a long-term way. Malcolm West, AEA Technology, shows you how.
According to the CBI, in the early 1990s contamination liabilities in the UK stood at £20bn. Changes in legislation, accounting and general business practices, as well as stricter enforcement, have meant that these liabilities are now more easily identified; polluters or landowners held responsible.

What do you know?
Environmental Diagnostics, a thematic research programme of the UK Natural Environment Research Council, set out in 1995 to provide a better scientific basis for the sustainable management of chemicals and to provide industry and government with tools that would help manage their manufacture, use and disposal.
Sustainability: spotlight on construction
Last month, IEM presented an ongoing project to relocate the Princess Margaret Hospital in Swindon according to the sustainability principles of The Natural Step. Since walls, floors and ceilings are integral to all buildings, they provide three obvious places to explore how more sustainable decisions were put into effect. By Jas Dhami, a building economist with Carillion Building, and Dr Mark Everard, The Natural Step.
