METHOD AND APPARATUS FOR PREVENTING MICROBIAL GROWTH IN DRINKING WATER

摘要

A drinking water filter inhibits retrograde bacteria growth at the user outl et with the combination of a non-carbonaceous submicron filter element (26) immediately upstream of the system outlet (17) and a copper orifice element (17) in the outlet downstream of the filter element. The copper orifice element preferably comprises a thin copper disc (31) having a single orifice (29). The submicron filter element (26) preferably comprises a hollow fiber bundle filter element.
