Temporary water treatment
June 1st 2007 Pfizer's European R&D Headquarters and manufacturing site in Sandwich, Kent, has seen substantial growth over the past decade. This has led to increased demands on the site facilities, in particular the boiler plant and its associated support systems such as the de-ionised water plant.
With 45 Bar Boilers, the de-ionised water plant is not just necessary to meet the Steam demand, but critical to safe operation. While plans to replace the boiler feed water plant with a new state of the art de-ionised water plant were well underway, contingency plans were required to ensure continuous operation of the existing plant through the winter of 2004/2005. To meet this requirement, Pfizer employed the use of,Elga Process Water's latest development, Aquamove,a Mobile/Emergency Water Treatment Service.
With experience of meeting Pfizer's standards for a supply of high purity water for laboratories, production and R&D facilities, reaching a clear understanding of their requirements for the deionised water and boiler feed plant proved straight forward. A project plan was quickly drawn up and agreed and a deployment date set.
Elga deployed two of its MORO24 units – Containerised Reverse Osmosis plants from its Stoke on Trent depot. To provide a fully integrated system, ELGA also provided a number of ancillary items, Each MORO24 container is insulated, ventilated and comes with appropriate Health & Safety equipment (eye wash, first aid kit, fire extinguisher, and so on). The RO units also feature controllable, Inverter Driven HP Pumps for energy efficiency and to help protect the RO Membranes. Each MORO was set to operate at around 17-18m3/Hr (well inside its 24-25m3/Hr capability), producing Permeate with Conductivity in the range 9- 10µS/cm. This quality of water being fed to the existing De-I plant extended the period between regenerations by a factor of 10, reducing operator involvement and improving reliability.
The MORO units and ancillaries were electrically interconnected to allow fully automatic operation.
Client training was provided, and ELGA provided round the clock assistance via its 24hr helpline.
