Abstract

In one of its aspects, the present invention relates to a fluid treatment system comprising: an inlet; an outlet; a fluid treatment zone disposed between the inlet and the outlet. The fluid treatment zone: (i) comprises a first wall surface and a second wall surface opposed to the first wall surface, and (ii) having disposed therein at least one array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis transverse to a direction of fluid flow through the fluid treatment zone and each of the first wall surface and the second wall surface comprises a first fluid deflector element and a second fluid deflector element. The first fluid deflector element projecting into the fluid treatment zone to a greater extent than the second fluid deflector element.

A fluid treatment system comprising:

an inlet;
an outlet;
a fluid treatment zone disposed between the inlet and the outlet, the fluid treatment zone comprising a first wall surface and a second wall surface opposed to the first wall surface;
a first radiation source assembly comprising a radiation source having a first longitudinal axis extending substantially transverse to a direction of fluid flow through the fluid treatment zone;
a first fluid receptacle portion disposed in the first wall surface to define (a) a first junction between the first fluid receptacle portion and the first wall surface and (b) a second junction between the first fluid receptacle portion and the first wall surface,
the first fluid receptacle portion comprising a first apex portion configured such that a first ratio of (i) a first distance between a first centerpoint of the first radiation source and the first apex portion, to (ii) a second distance between the first centerpoint and the first junction is greater than or equal to 1,
the first fluid receptacle having a cross-section extending in a direction transverse to (i) the first longitudinal axis and (ii) a longitudinal axis of the first fluid receptacle portion, said cross section comprising a rectilinear shape,
a distance C between (i) a line extending from the first junction to the second junction to (ii) a closest outermost surface of the first radiation source assembly, being greater than zero, wherein the radiation source assembly is on the side of line closer to the fluid treatment zone than to the receptacle.
