Partitioned water treatment systems with vertical filtration units
The present invention supplies partitioned water treatment systems that possess a plurality of chambers and vertical filtration units, and are operative to control and filter surface runoff water. Such systems are typically placed inline with surface runoff water conveyance system infrastructure, such as pipes, channels, and water storage units.
1. A collection rail configured for installation in a partitioned water treatment system that comprises a discharge chamber wall to partition the water treatment system into a filtration chamber and a discharge chamber, the collection rail comprising a duct and multiple filter assemblages, the duct having an exit opening;
each of the multiple filter assemblages 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 multiple filter assemblages 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 multiple filter assemblages, through the duct into the discharge chamber,
wherein the vertical filter of at least one of the multiple filter assemblages consists of a sheet of filter material formed into a cylinder closed by a top end that is water impermeable and a bottom end that is water impermeable apart from an opening through which water can flow, and wherein the coupler is adapted to place the opening in the bottom end of the vertical filter in sealed, fluid communication with the filter opening of the at least one of the multiple filter assemblages,
wherein the sheet of filter material comprises back and forth folds that form a series of pleats;
wherein the sheet of filter material forms an outwardly facing exterior surface of the at least one filter assemblage such that (i) the sheet of filter material is exposed directly to water in the filtration chamber and (ii) in order to pass through the filter assemblage water first enters the filter assemblage directly via passing through the sheet of filter material.
2. The collection rail of claim 1 , wherein the sheet of filter material is selected from the group consisting of a plastic, a paper, a fiberglass, and a combination thereof.
3. The collection rail of claim 1 , wherein the coupler of at least one of the multiple filter assemblages is adapted to removably mount the vertical filter on the duct.
4. The collection rail of claim 3 , wherein the coupler comprises hardware selected from the group consisting of a friction fitting, a pressure fitting, a threaded fitting, a bolt, a screw, a nail, and a clamp.
