A medical devices manufacturing factory, owned by a multinational
company, is selected as a typical industrial waterconsuming
facility in order to discuss the application of
the water value system methodology. The factory has a
single water supply from a municipal source and is also
investigating the possibility of rainwater harvesting. The
primary water systems, along with the relevant treatment
processes and flow paths within the factory, are illustrated
in the PFD in Fig. 2, which was developed from a compilation
of drawings, site inspections and interviews with operational
personnel.
