Getting toned up
One of the huge range of fine chemical products manufactured by Avecia at their Grangemouth site is a new chemically produced toner for use in copiers and printers
This new product material is at the forefront of electrophotography, with a precision controlled particle size and improved powder characteristics that mean high resolution colour and black and white printing with less dust and lower toner scatter The final stage in the manufacturing process is filtration of the toner and washing with high purity water

Ion exchange resin supply and regeneration
The Elga Process Water regeneration station has now processed more than a million litres of ion exchange resin for their cylinder exchange service in the three years since it was completed

Cooling water treatment systems supplied to Urenco use ion exchange resins and an ultraviolet lamp unit to control microbiological growth
Nuclear Fuel Keeps Its Cool
Urenco, the uranium enrichment specialists, have awarded a contract to Vivendi Water Systems for the supply of cooling water treatment equipment at their new facility in the North West of the UK
At the moment the material is manufactured at pilot scale, and uses about 160 cubic metres of deionised water each week.
The pilot plant posed an interesting problem.
"Although there is deionised water on site, there was no supply near enough for us to connect into." says Jeff James of Avecia.
With capital expenditure initially restricted and time pressing, the development team opted to use the Vivendi Water Systems Cylinder Exchange Service.
Cylinder exchange was introduced by Vivendi Water Systems (based in High Wycombe, Bucks) back in 1955 and the company has been the UK's leading supplier of the service ever since.
The concept is simple: Vivendi Water Systems provide a cylinder, similar to a compressed air cylinder, containing mixed-bed ion exchange resins.
Jeff connects it to a mains water supply and it produces high purity deionised water.
When the resins are exhausted the cylinder is taken off-line and replaced with a spare, meanwhile the exhausted cylinder is returned to Vivendi Water Systems for regeneration in exchange for a new cylinder.
Vivendi Water Systems operate their own transport fleet and deliver directly to the point-of-use, this ensures that cylinders are handled correctly and that the client is not inconvenienced.
There is no expensive plant and no regeneration chemicals to handle, just a cylinder to change for the spare one held in the Avecia store.
"The necessary equipment was delivered from stock and we had deionised water on tap within a matter of days" says Jeff.
"When we move up to full scale manufacture we'll install a permanent deionised water system, but the convenience and flexibility of the Cylinder Exchange Service means that we'll be able to relocate it to another pilot plant".
Vivendi Water Systems is proud to be helping the UK fine chemical industry to stay ahead of the rest of the world.
