Editorial T

his year marks the 40th year of publication of the Filtration+Separation magazine, established back in the early 1960s by the late William (Bill) Norris and Mike Taylor. In the

intervening years the magazine has evolved from the official publication of The Filtration Society (UK) to an international engineering trade magazine, with a global readership of over 10 500. However, throughout all the changes it has remained dedicated to promoting the latest developments in liquid, air and gas filtration and separation technology, and will continue to do so. During 2003 we will be celebrating this anniversary in a number of ways, including focusing on how certain filtration and separation technologies have evolved over the past 40 years, as well as republishing specific articles of interest. We also hope to hold a drinks reception during Filtech Europa 2003 (DOsseldorf, Germany) in October to mark this anniversary.

In this first issue of 2003 we focus on membrane separation technologies. We begin with a look at the development of the membrane bioreactor and the importance of the membrane component of this technology. The success of treating spent acid solutions with crossflow microfiltration prior to entry into acid recycling plants is also discussed. We round off the membrane focus with a study that indicates vibrating membrane systems may be a more effective method of preventing mineral scale fouling of RO membranes than traditional crossflow systems.

Finally, our new web site has been launched. It contains a host of useful features for anyone interested in filtration and separation. There are daily business news up~lates, new product launches and the latest technical features, as well as our on-line Buyers Guide. The new web site can be found at the same URL address as our previous site (www.filtsep.com). We will continue to develop the site throughout the year, so your comments on the new and improved site and the services that it offers are welcome.
