System for pollution suppression
First Claim
1. A disinfectant mixing system for an influent treatment system utilizing a contact tank which comprisesan influent inlet port into the contact tank,a manifold fed by the inlet port,a pipe bundle fed by said manifold,a flat plate orifice high momentum exchange mixing member in each pipe in said bundle,means for injecting a disinfecting fluid into each pipe at the point of highest momentum exchange,an influent well,means to effect influent flow from the influent well to the contact tank,an effluent well,means to effect flow from the contact tank to the effluent well, anda hyperbolic transformed diffuser to deliver the influent from the pipe bundle to the influent well.

Abstract
A surge suppression system for dampening surge pressures or pipe hammer by introducing a gas into a flow conduit in such an amount that the introduced gas is in excess of that required to saturate the liquid. Preferably, the gases are those which are relatively inert or not unduly reactive and which possess relatively low saturation levels with respect to the liquid. Desirably, the gas is added through a member to the flow conduit in a vicinity of high turbulence. The surge suppression system can be utilized in generally any liquid system and particularly in a liquid transmission system.
Another embodiment pertains to a scrubber or washer for generally purifying gases and may contain one or two stages to efficiently remove impurities as through the use of high solubility fluids, fluids which decompose contaminants or which contain or provide (i.e. heating stage) catalysts to decompose contaminants, oxidizing agents, or reducing agents. The scrubber contains a packed bed and the packing may be characterized as one where the inside hydraulic radius equals the hydraulic radius of the external flow channels. The washer or scrubber type apparatus is particularly suitable for treating (purifying) materials such as ozone utilized in a deodorizing or disinfecting system.
Another embodiment pertains to the purification of a gas by treatment with a fluid in a flow conduit having a plug flow at its entrance containing an injection-mixing device coacting with a first high turbulence causing device and a downstream or second high turbulence causing device. The treating fluid is preferably added at the vena contracta of the first high turbulence causing device.
