Fluid flow director for water treatment system

Abstract

A plastic fluid flow director for a water treatment system is provided having a plastic substrate with a protective coating that is substantially opaque to UV light. The plastic substrate may be ultra-high molecular weight polyethylene and the UV opaque coating may be unexpanded polytetrafluoroethylene (“PTFE”). The UV opaque coating protects the plastic substrate from UV light, which may be destructive to the plastic, during the water treatment process. The coating is suitable for water contact, does not break down in the presence of ultraviolet light for extended periods, and otherwise works with conventional water treatment systems. The plastic substrate with UV opaque coating is a suitable replacement for a stainless steel fluid flow director.
