Abstract: A proportionate automated blending system for aqueous mixtures has a plurality of liquid additive control modules which each provide a desired amount of additive to a dedicated mixing injector to blend each additive with water to provide a precise mixture of additive and water. The system has the capability, in between blending cycles, of purging the components of the additive control modules with air and water to displace any residue additive which may remain in the control module. The system is controlled by a controller which controls an actuated control valve to achieve the desired flow rate of liquid additive to acquire the desired proportion of liquid additive to water.

Abstract: The invention has to do with the re-entrainment of gases separated from a water/gas mixture that rise to the top of a conductor pipe. A water jet created by a nozzle of the present invention plunges though the surface of the water carrying with it the gas that has accumulated on the surface on the water between the water and the top of the conduit. Depending on the gas to liquid ratio and the velocity of the mainline water flow, the nozzles penetrate the conductor pipe adjacent to a point where the gas has accumulated and no longer is entrained and mixed with the water. The ratio of plunging water to main water flow is determined based on the upstream injected gas to liquid ratio for the treatment process such as oxygen for aerobic conditions or ozone for oxidation.
