1. An apparatus for the treatment of a liquid comprising:
a chamber being enclosed by at least one wall having at least one inner surface, the inner surface of the at least one wall enclosing the chamber;
an ultraviolet lamp, the ultraviolet lamp being disposed within the chamber, the ultraviolet lamp producing ultraviolet photons;
an ultraviolet transmissive tube including an interior and a continuous interior-facing surface surrounding the interior, the ultraviolet transmissive tube being made of a material that is transmissive to ultraviolet light, the ultraviolet transmissive tube being disposed within the chamber and adapted to permit a fluid to pass through the chamber by flowing through the interior of the ultraviolet transmissive tube, wherein the fluid within the chamber is fully contained by the interior-facing surface within the ultraviolet transmissive tube, the ultraviolet transmissive tube having an outer surface that faces the inner surface of the at least one wall enclosing the chamber;
a reflective surface enveloping the ultraviolet lamp by at least 80 percent; the reflective surface adapted so as to reflect at least a portion of light emitted by the ultraviolet lamp, wherein the reflective surface is at least 80 percent reflective, wherein the reflective surface is disposed on the outer surface of the ultraviolet-transmissive tube;
wherein enveloping of the lamp by at least 80 percent and the reflectivity of the reflective surface being at least 80 percent are effective to deposit a majority of the ultraviolet photons within a volume of the fluid;
wherein the ultraviolet lamp is disposed within a transmissive protective sleeve within the ultraviolet-transmissive tube.
