<p>A mixing, aerating or oxygenating apparatus to aerate or oxygenate ponds, rivers or lakes, sewage or effluent treatment lagoons or beds or to airstrip volatile compounds from water or other solutes by distributing gas through a piped system having a plurality of outlets branching from a common distribution line. In order to deliver a desired quantity of air or oxygen at each outlet, a constant flow regulator is disposed in each outlet which limits the flow to a set amount when the pressure in the pipe system exceeds a predetermined minimum value. In one embodiment, the regulator is chosen to achieve this irrespective of pressure drop along the distribution line. In another embodiment, the regulator is chosen to give the desired output with no pressure drop along the distribution line.</p> |
