ELGA Process Water's regeneration station has regenerated more than a million litres of ion exchange resin for its cylinder exchange service.
Cylinder exchange is a convenient means of producing high purity water, according to the company. The cylinder containing mixed bed ion exchange resins is connected to the water supply, and the resin removes dissolved impurities to produce high quality water. When it is exhausted, it is returned to ELGA Process Water in exchange for a recharged cylinder.
The fully automatic resin regeneration facility handles the regenerant chemicals and monitors the wastewater produced in the process in accordance with ELGA Process Water's ISO14001 aligned Environmental Management system.
Each regenerated batch of resin undergoes detailed quality control laboratory tests to ensure that it complies with ELGA Process Water's stringent standards. Once the cylinders are loaded with resin they are bar coded so that the resin batch from which they were filled and the exact regeneration conditions can be traced.
ELGA Process Water operates its own fleet of trucks for delivery and collection of cylinders, so traceability extends to the time of delivery and even the driver's name. For ELGA Process Water's customers like pharmaceutical manufacturers and scientific research establishments, this level of traceability is a prime requirement for their own quality systems.
