Gloucestershire based measuring equipment manufacturer, Renishaw uses Mecwash Midi 400 aqueous based washing machines to remove cutting oils from its precision machined components. The company also uses ELGA Process Water Aquaclean service exchange cylinders to improve the quality of demineralised water by an order of magnitude, which eliminates staining, particularly on satin chrome plated components.

Renishaw uses two ELGA Process Water Aquaclean cylinders in series, the first containing activated carbon and the second containing a mixed bed of cation and anion exchange resins. Water from the rinse tank is recirculated and its quality is upgraded to about 5µS/cm, thus reducing mains water consumption and eliminating the need to discharge into the local sewerage system.

Service exchange users like Renishaw have a duty of care to ensure that their wastes are disposed of safely. In the case of resin disposal, this means having a fully documented audit trail to trace their resins route from the process finishing areas to its ultimate fate.
