Claim:
An integrated aeration system, comprising: a closed water tank system including a enclosed water tank having a bottom portion adapted for holding a pool of water and a top portion sealing in air above the pool of water; a nozzle disposed in the top portion of the closed water tank, the nozzle having air bleeder passages allowing ambient air to flow through the nozzle and into the closed water tank; a headspace pressure valve disposed in the top portion of the closed water tank, the headspace pressure valve measuring headspace pressure developed inside the closed water tank; to a water flow meter; a water pump circulating water from the bottom portion of the closed water tank outside the tank through the flow meter and then through the nozzle at the top portion of the closed water tank, the nozzle entraining air through the bleeder passages into the water as the water passes through the nozzle and forming a jet spray into the pool of water in the bottom portion of the closed tank in order to aerate the pool of water in the closed water tank, head space pressure being developed in the top portion of the closed water tank when the closed water tank is partially filled with water; an open water tank system including an open water tank; an air flow valve; and a closed water tank air outlet pipe extending from inside the top portion of the closed water tank through the air flow valve and connecting the closed water tank system to the open water tank system, the closed water tank air outlet pipe having a perforated portion extending along a bottom inside portion of the open water tank, the perforated portion being adapted for diffusion air into a second pool of water in the open water tank system in order to aerate the second pool of water.
