Abstract

An apparatus and methods are disclosed for purifying fluid, such as potable water, to quality levels suitable for medical application, particularly to applications involving injection of the fluid into a human body. The apparatus comprises a portable purification pack (12) constructed for a single use. The pack (12) houses depth filtration (26), activated carbon (28), mixed bed ion exchange resins (32) and terminal filtration (36) stages in series.
The terminal filter (36) comprises a fine (microfiltration or ultrafiltration), permeable membrane, treated with an endotoxin-binding chemistry. In contrast with semi-permeable osmotic membranes, the permeable membrane produces high flow rates at relatively low pressures, while still safely purifying fluid to injection quality.
