Making de-ionisation cylinders more
sustainable.
More and more industries are finding the benefits of using de-ionised water: Elga now offers an economical range of anion cylinders that produce 20uS/cm conductivity water, with a higher capacity
Glass washing, bottle rinsing, car washes and surface treatment are just a few of applications in which a final de-ionised water rinse gives improved product quality Most of these applications depend on service exchange cylinders using mixed bed ion exchange resins to purify the water

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
When the resins are exhausted the service provider delivers a replacement cylinder and returns the exhausted one to their regeneration station for reprocessing.
Most de-ionisation cylinders use strong anion exchange resins which produce high purity water with conductivity less than 0.2uS/cm - a hundred times purer than is needed for most applications.
Elga Process Water has introduced a range of weak anion cylinders that produce water of about 20uS/cm conductivity - good enough for all but the most critical applications.
The weak resin cylinders have a capacity around 80% higher than conventional cylinders and are available in sizes to suit all users with flow rates from 140 l/h of de-ionised water, up to 2,835 l/h, with capacities up to 7000Ltr when treating a typical 400mg/l TDS mains water.
The increased capacity of the Elga Process Water weak anion resin cylinders means greatly reduced operating costs.
Not only that, weak anion resins are very efficient in regeneration, so there is less regenerant chemical consumption, and fewer cylinder deliveries leaves a smaller carbon footprint.
