RACEWAYS AND SYSTEMS THEREOF
Embodiments of the present disclosure describe a raceway comprising a sloped base with an apex, a divider extending upward from the apex, two side walls, each opposing and parallel to the divider sufficient to form two elongated channels on the sloped base; and at least two tapered ends in fluid communication with the channels, each tapered end including an end wall, a pit, and a sloped floor extending from the sloped base to the end wall or pit.
1 . A raceway, comprising:
a sloped base with an apex,
a divider extending upward from the apex,
two side walls, each opposing and parallel to the divider sufficient to form two elongated channels on the sloped base; and
at least two tapered ends in fluid communication with the channels, each tapered end including:
an end wall,
an optional pit, and
an optional sloped floor extending from the sloped base to the end wall or pit.
2 . The raceway of claim 1 , wherein the divider minimizes turbulent flow in each channel.
3 . The raceway of claim 1 , wherein a length of the divider and apex is the same.
4 . The raceway of claim 1 , wherein a length of the divider is less than a length of the apex.
5 . The raceway of claim 1 , wherein the channels have a symmetric configuration.
6 . The raceway of claim 1 , wherein the channels have an asymmetric configuration.
7 . The raceway of claim 1 , wherein each channel includes one or more of an expansion zone, a contraction zone, and a non-expansion zone.
8 . The raceway of claim, wherein the expansion zone encourages settling of molts and/or wastes and the contraction zone increases a fluid flow rate.
9 . The raceway of claim 1 , wherein each of the two channels includes an expansion region and a contraction region and the corresponding expansion regions and contraction regions of the two channels have the same cross-sectional area and/or angle relative to a horizontal axis line along the length of the channels.
10 . The raceway of claim 1 , wherein the recovery zone encourages settling of molts and/or wastes.
11 . The raceway of claim 1 , wherein at least one of the recovery zones includes at least one corner insert.
12 . The raceway of claim 11 , wherein the at least one corner insert is rounded.
13 . The raceway of claim 11 , wherein the at least one corner insert is straight.
14 . The raceway of claim 1 , wherein the recovery zone further comprises one or more of an inlet and a pump.
15 . The raceway of claim 14 , wherein the inlet is included in the end wall and is provided in-line with an outlet channel.
16 . The raceway of claim 1 , wherein the raceway collects molts and/or removes wastes.
