4.1 Theory of Operation
The Millenium HX Portable Reverse Osmosis system (RO) is a fully cabinetized unit that
purifies a given feed water (by way of reverse osmosis) for use in hemodialysis
applications. The RO possesses monitoring for RO feed water pressure, RO feed water
quality, pump outlet pressure, product water pressure, product water temperature,
product water quality and membrane performance (percent rejection). The RO pump
provides the pressure required to push water through the RO membrane. The fluid
controls provide a means of managing flow rates and pressures. The following
paragraphs detail the function of these fluid control components, which are used within
the RO.
