The Medical Research Council required 1000 litres per hour of sterile, ultra high purity water (18M W .cm) for use in their new biotechnology research facility at Addenbrookes Hospital, Cambridge.


System design, detailed process design, equipment specification and project management.

The system comprises duty and standby base exchange softeners, reverse osmosis, storage and polishing. The polishing plant consists of a standard strong cation - strong anion deioniser with a cation polishing unit producing water of 17M W .cm quality followed by a non regenerable mixed bed unit and 0.1µm membrane filters to remove bacteriological contaminants. The polished water is delivered into a ring main for distribution around the laboratory with unused water returning to the storage tank.
