<ul><li><p>This month we publish a series of features on the subject ofseawater desalination, which continues to gain acceptance inmunicipal, industrial and commercial applications. Traditionally,desalination projects have been viewed as extremely expensive,because of the high-power demands placed on plants, the cost ofreplacing membranes and the amount of pre-treatment neededbefore desalination can take place. However, recent innovations most notably in the Reverse Osmosis (RO) field have brought aboutnewer and more efficient technologies, and this is driving downpotential costs of operating desalination plants. And perhaps moreimportantly, the alternatives to seawater are diminishing; accessiblefresh water reserves are becoming harder to find and increasinglycostly to exploit, partly because the environmental cost of theirexploitation has to be taken into account; and over-exploitedgroundwater reserves are also becoming progressively more salinedue to seawater intrusion. So as time passes, maybe the questionposed in certain countries and regions should change from 'can weafford to consider it?' to 'can we afford not to?'</p><p>12-15 April will see the three-yearly Nonwovens Index show takeplace in Geneva, Switzerland (Index05). According to those in the field,the 400+ exhibitors represent a good cross section of the Nonwovensindustry, and this should prove interesting for visitors wanting to findout about the latest Nonwovens developments in the filtration industry.Our Nonwovens feature starting on page 26 aims to give you a 'heads-up' before the event.</p><p>David HopwoodEditor</p><p>www.filtsep.com</p><p>Water for thenext generation</p><p>March 2005 3</p><p>In the next issue...
