Abstract

A liquid processing apparatus comprised of a housing comprising a bottom wall, a side wall, and a central wall dividing a volume enclosed by the bottom wall and side wall into a treatment chamber and a discharge chamber; and a cartridge disposed in the treatment chamber. The cartridge may be comprised of a base wall and a lateral wall forming a media chamber, and a plurality of passageways through at least one of the base wall and side wall rendering the media chamber in communication with the treatment chamber. A treatment medium is contained in the media chamber. The cartridge may be comprised of a plurality of divider walls partitioning the media chamber into media compartments. The housing may be further comprised of a plurality of locating walls extending vertically upward from the bottom wall of the housing and between the divider walls of the cartridge.

Claims15

Dependent claims

A liquid processing apparatus comprising:

a) a housing comprised of:
a bottom wall;
a side wall;
a central wall.
a first end joined to the side wall and a second end joined to the side wall, and dividing a volume enclosed by the bottom wall and side wall into a treatment chamber and a discharge chamber;
and
a plurality of baffle walls extending vertically upward from the bottom wall of the housing and into the impermeable divider walls of the cartridge, and extending transversely across the treatment chamber between opposed portions of the side wall of the housing;
and
b) a cartridge disposed in the treatment chamber and comprised of a base wall and a lateral wall forming a media chamber, a plurality of impermeable divider walls extending vertically upward from the base wall and partitioning the media chamber into a plurality of separate media compartments, and a plurality of passageways through at least one of the base wall and the lateral wall rendering the media chamber in communication with the treatment chamber;
wherein the impermeable divider walls are each formed with a hollow upward cavity, and wherein the baffle walls extend upwardly into the upward cavities of the divider walls;
wherein the hollow upward cavities of the impermeable divider walls have an upward V-shape, and the baffle walls have a corresponding upward V-shape and are engaged with the V-shaped cavities of the impermeable divider walls;
and
wherein the V-shaped baffle walls engage in a liquid-impermeable seal with the V-shaped cavities of the impermeable divider walls.
