Partitioned water treatment systems with vertical filtration units

A partitioned water treatment system comprised of a box configured for installation into a flow stream of SRWC infrastructure, the box possessing a ceiling, a floor, two lateral walls, two endwalls, an inflow opening, an outflow opening, a discharge chamber wall, a separation chamber wall, and one or more collection rail(s), wherein:

• the discharge chamber wall is in sealed connection with the floor and the two lateral walls, but not the ceiling and the separation chamber wall is in sealed connection with the floor, one of the endwalls, and the discharge chamber wall, but not the ceiling, such that the discharge chamber wall and the separation chamber wall partition the box into a separation chamber that abuts the inflow opening, a filtration chamber, and a discharge chamber that abuts the outflow opening,
• the inflow opening:
• i. is positioned in the ceiling, one of the lateral walls, or one of the endwalls;
• and ii. is in sealed, fluid communication with the SRWC infrastructure upstream of the partitioned water treatment system,
• the outflow opening:
• i. is positioned in the floor in or in proximity with the floor in one of the two lateral walls or one of the two endwalls;
• and ii. is in sealed, fluid communication with the SRWC infrastructure downstream of the partitioned water treatment system,
• each of the one or more collection rail(s) comprises:
• i. a duct that extends from the discharge chamber to the filtration chamber, sealingly through the discharge chamber wall, and ii. one or more filter assemblage(s):
• the one or more filter assemblage(s) comprising a vertical filter, a filter opening in the duct, and a coupler that mounts the vertical filter on the duct and places the vertical filter and the filter opening in sealed, fluid communication,
• the duct comprising an exit opening in the discharge chamber and configured such that:
• i. each of the one or more filter assemblage(s) are positioned in the filtration chamber, and ii. the duct is water impermeable apart from the exit opening and the filter opening of each of the one or more filter assemblage(s), and
• the collection rail is operative to allow water to flow from the filtration chamber to the discharge chamber by passing through at least one of the one or more filter assemblage(s), the duct, and the exit opening,
• the top of the discharge chamber wall and the top of the separation chamber wall are positioned in the box such that in conditions of:
• i. low to moderate water flow through the system, a flow path of water is from the inflow opening into the separation chamber, over the separation chamber wall into the filtration chamber, through at least one of the one or more collection rail(s) into the discharge chamber, and through the outflow opening, and
• ii. high water flow through the system, an additional flow path of water is from the inflow opening into the separation chamber, over the discharge chamber wall into the discharge chamber, and through the outflow opening.

A collection rail configured for installation in a partitioned water treatment system that comprises a filtration chamber and a discharge chamber, the collection rail comprising a duct and one or more filter assemblage(s),

• the duct comprising an exit opening located in or near an end of the duct,
• the one or more filter assemblage(s) comprising a vertical filter, a filter opening in the duct, and a coupler that mounts the vertical filter on the duct and places the vertical filter and the filter opening in sealed, fluid communication,
• the duct configured to position, when installed in the water treatment system:
• i. each of the one or more filter assemblage(s) in the filtration chamber, and ii. the exit opening in the discharge chamber, and
• the collection rail configured to establish, when installed in the water treatment system, a flow path for water from the filtration chamber through at least one of the one or more filter assemblage(s), through the duct, through the outflow opening, and into the discharge chamber.
