A method of recycling unused gases in a water aeration process includes providing a confined plunging liquid jet reactor system; producing a water jet at an outlet of a nozzle; entraining air in the water jet as the water jet flows from the outlet of the nozzle to obtain an entrained air water jet; entraining oxygen in the entrained air water jet to obtain an entrained oxygen air water jet; flowing the entrained oxygen air water jet into a water in a fluid reservoir thereby forming small water bubbles as the entrained oxygen air water jet penetrates into the water; forming large water bubbles as the small water bubbles ascend toward the surface layer of the water; and recycling unused gases under a hood by flowing the unused gases toward the outlet of the nozzle, thereby entraining the unused gases in the entrained air water jet.

A dilution device may include a first component and a second component. The first component may define a groove including an inlet portion and an outlet portion. The second component may define an inlet in fluid communication with the inlet portion of the first component and an outlet in fluid communication with the outlet portion of the first component.
