Mixing, aeration or oxygenating method and apparatus
First Claim
1. A method of mixing, aerating or oxygenating ponds, rivers or lakes, sewage/treatment lagoons or effluent beds or air striping volatile compounds from water or other solutes, the method comprising the steps of:
- (a) providing a pipe system having a plurality of outlets branching from a common distribution line;
(b) continuously providing a predetermined minimum volume of a gas comprising oxygen and introducing the gas into the pipe system; and
(c) delivering a desired constant quantity of the gas at each of the outlets by providing a moving element constant flow regulator means for each outlet which limits gas flow from each of the outlets to a constant amount when pressure in the pipe system exceeds a predetermined minimum value.

Abstract
A mixing, aerating or oxygenating method and 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 (4) branching from a common distribution line (2). In order to deliver a desired quantity of air or oxygen at each outlet, a constant flow regulator (5) 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 method, the regulator is chosen to achieve this irrespective of pressure drop along the distribution line. In another method, the regulator is chosen to give the desired output with no pressure drop along the distribution line.

6. A mixing, aeration or oxygenating system 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 and comprising:
-
(a) a pipe system having a plurality of outlets branching from a gas distribution supply line;
(b) a source of pressurized gas comprising oxygen connected to the distribution supply line; and
(c) an “
O”
ring moving element constant flow regulator for each outlet to cause a desired constant flow of gas to be delivered through the outlets when pressure in the pipe system exceeds a predetermined minimum value, each regulator in designed to only allow a desired maximum flow of gas to pass through at a known pressure of gas.- View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
