LOW PROFILE CASCADE AERATOR

摘要

A cascade aerator comprising a plurality of longitudinal channels that receive a fluid therethrough. The longitudinal channels are in fluid communication with a plurality of flow control gates, such that a first number of flow control gates are in fluid communication with a first longitudinal channel and a second number of flow control gates are in fluid communication with a second longitudinal channel. The first number of flow control gates may define a crest height that is lower, along a vertical direction, than a crest height defined by the second number of flow control gates. The flow control gates may define a crest length proximate a crest of the flow control gate and a nappe length defined proximate a first height above the crest. The nappe length may be greater than the crest length. The aerator may have a plurality of low head baffles.

1. A cascade aerator for increasing the level of dissolved oxygen flowing therethrough comprising:
a plurality of longitudinal channels configured to receive a fluid therethrough; and a plurality of flow control gates, wherein a first number of flow control gates are in fluid communication with a first longitudinal channel and a second number of flow control gates are in fluid communication with a second longitudinal channel, wherein the first number of flow control gates define a crest height that is lower, along a vertical direction, than a crest height defined by the second number of flow control gates.
