Low profile cascade aerator

A cascade aerator for increasing the level of dissolved oxygen flowing therethrough comprising:

• a plurality of longitudinal channels configured to receive a fluid therethrough;
• 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 plurality of flow control gates define a crest length defined proximate a crest of the flow control gate, and a nappe length defined proximate a first height above the crest,
• wherein the nappe length is greater than the crest length;
• a plurality of low head baffles extending from respective base surfaces of the first and second longitudinal channels;
• and
• a plurality of aeration plates extending from the plurality of low head baffles,
• wherein the plurality of aeration plates extend from low head baffles to define a plurality of openings configured to allow the fluid to flow therethrough,
• wherein each opening defines a baffle crest length defined proximate a crest of the low head baffle, and a baffle nappe length defined proximate a second height above the crest of the low head baffle,
• wherein the baffle nappe length is greater than the baffle crest length.
