  • Patent number: 9931602
    Abstract: An apparatus and method for increasing the mass transfer of a treatment substance into a liquid flowing in a pipe in a full pipe flow regime has a diversion conduit which receives a portion of the liquid. The portion of the liquid is mixed with a treatment substance and then reintroduced into the pipe at a downstream location through an injection structure. Between the diversion conduit, on the upstream side, and the injection structure, on the downstream side, there are a plurality of flow vanes disposed circumferentially about a cylindrical inner wall of the pipe, where each flow vane extends radially inward toward a central axis of the pipe, extending into the main stream flow of the liquid. Another embodiment of the invention has a flow grid located downstream of the injection structure.

  • Patent number: 9744502
    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.

  • Publication number: 20110089108
    Abstract: An aeration and filtration system and process for treating wastewater is described, the system having an ejector able to mix gas and liquid, an oxidation tank able to contain a solution of wastewater and biological sludge, a filtration means, a pipe able to convey the wastewater and biological sludge solution from the oxidation tank to the filtration means. The pipe is connected to the ejector so as to introduce a turbulence inside the pipe; moreover the filtration means is equipped with a membrane which has micropores.
