1. A sorbent cartridge system, comprising:
- a sorbent cartridge comprising i) a continuous sidewall extending between a fluid inlet and a fluid outlet, which define a chamber, ii) at least one layer comprising solid particulate media, wherein the at least one layer extends across the chamber within the continuous sidewall, and the at least one layer comprises a first region and a second region adjacent the first region and located closer to the continuous sidewall than the first region; and
an intake manifold comprising at least one first discharge port and at least one second fluid discharge port, wherein the intake manifold and sorbent cartridge are positionable with respect to each other to locate the first region of the sorbent cartridge for fluid communication with the at least one first discharge port and locate the second region of the sorbent cartridge for fluid communication with the at least one second fluid discharge port, wherein the intake manifold is configured wherein a first volumetric flow rate of fluid discharged at the first fluid discharge port into the first region is greater as compared to a second volumetric flow rate of fluid discharged at the second fluid discharge port into the second region,wherein the intake manifold comprises i) at least one central branch passageway comprising a first hydraulic diameter and the at least one first discharge port, ii) at least one peripheral branch passageway comprising a second hydraulic diameter and the at least one second discharge port, and iii) a fluid feeding passageway for supplying fluid concurrently to the at least one central branch passageway and the at least one peripheral branch passageway, wherein the first hydraulic diameter of the at least one central branch passageway is greater than the second hydraulic diameter of the at least one peripheral branch passageway.
