Level four of the new building houses the renal wards, where 106 points of use have been installed, providing 55 dialysis stations, eight of which are in the isolation ward and five in the adjacent High Dependency Unit.
Veolia Water Technologies’s engineers worked closely with the hospital’s renal technicians to engineer a custom water purification and distribution system, which will also reduce the carbon footprint.
Each ultrafiltration unit feeds separate ring mains, each supplying approximately half the dialysis stations, with excess permeate being recycled. Using two separate ring mains ensures that half the dialysis stations are always available even when one ring main is under maintenance. The rings mains have a total of 1700 metres of orbitally welded hygienic 316L stainless steel pipe work, and are fully lagged to reduce heat losses during the automatic heat sanitisation cycles.
