US 2017/0291831 A1 · UV REFLECTIVE SYSTEM INCLUDING A THIN PLASTIC COATED ALUMINUM REFLECTOR OR A THIN PLASTIC REMOVABLE BLADDER

Abstract

A water purification system includes one or more UV light sources that produce germicidal UV light and provide the UV light to a given amount of fluid contained in a chamber as a batch or as flowing through the chamber. An inner surface of the chamber, that may be reflective, is coated with a thin plastic film, such as polypropylene, that is highly transmissive to UV germicidal light. The thin plastic film separates the inner surface from the fluid, and the UV light passes through the thin plastic film to reach the fluid that is being purified in the chamber. The thin plastic film may be melted at relatively low temperatures to provide heat sealing of the surface to produce the chamber. Alternatively, the thin plastic film may be readily shaped as a bag or pipe that contains or directs fluid flow.

Dependent claims

A water purification system including

one or more ultraviolet (UV) light sources that provide germicidal UV light to a given amount of fluid contained in an amplifying chamber;
a power source that drives the one or more UV light sources to provide to the fluid a fraction of a total UV energy required to purify the given amount of fluid;
and
the amplifying chamber having a highly reflective inner surface that is coated with a thin plastic film that is highly UV-transmissive, the inner surface redirecting through the thin plastic film and through the fluid in substantially all directions the UV light that reaches the reflective inner surface, to provide to the fluid a required dose of UV light to purify the fluid.
