Theory Of Operation - GE MILLENIUM OSMONICS MILLENIUMTM REVERSE OSMOSIS UNIT Operation And Maintenance Manual

WATER PURITY:
Plumbing materials can significantly contribute to the contamination of the water.
Metallic pipes (with the exception of 316 stainless steel) must be eliminated once
the purification process has begun. Schedule 40 or 80 PVC pipes, polypropylene,
PVDF, and other FDA recommended materials are suitable for most grades of
purified water. Care must also be exercised in the choice of a thread sealant.
Teflon tape is suitable for all threaded connections in this system.
WARNING:
Ordinary pipe dope must be avoided since it may leach objectionable and
potentially dangerous impurities into the water.

Theory of Operation

The Millenium™ 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 Millenium™ RO possesses monitoring for pressure, product water
quality and membrane performance (percent rejection). The RO pump provides the
pressure required to push water through the RO membranes. 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.
