  • Page 10: Product And Process Description

    PRODUCT AND PROCESS DESCRIPTION Product Description The MEDICA range of water purification units has been specifically designed to distribute and maintain purified water for laboratory, medical and industrial applications. The supply of purified water is obtained from either an external source or internal technologies. Purified water may be distributed around the installation under pressure to single or multiple points of use.

  • Page 11: Process Description

    Process Description MEDICA - R200 US • Feed water enters through a control valve (V1), and through a particulate filter (FH1) into the inlet of the RO pump (P1). Pressure in the pipework of the pump inlet is monitored with a pressure switch (PSW1) to ensure that the pump cannot run without sufficient water.

  • Page 12: Flow Diagram For Medica - R200 Us

    • The purified water is then passed through the UV (UV1) chamber where it is exposed to intense UV radiation to provide continuous bacterial control and to promote the cleavage of organic molecules before passing through an absolute 0.2µm bacterial and particulate filter. The difference in pressure between PG3 and PG4 can be used to monitor the condition of the filter.
