Appl. No.:

5/616487

Inventors:

Edward T. Armstrong - Butler NJ

Assignee:

TII Corporation (Telecommunications Industries, Inc.) - Lindenhurst NY

International Classification:

F16K 1900

US Classification:

137604

Abstract:

An apparatus for the treatment of purification of a fluid by treatment with a treating fluid in a flow pipe. The flow pipe has a flat plate orifice located therein, which orifice has an internal diameter of from about 0. 7 to about 0. 9 of the internal diameter of the pipe. A vena contracta portion is located in the flow pipe at a distance of from 0. 25 to 0. 5 pipe diameters downstream from said flat plate orifice. An injection nozzle for introducing the treating fluid into the flow pipe extends through the flat plate orifice with the tip of the injection nozzle being located in the vena contracta portion so that the fluid is thoroughly treated by the treating fluid.

Inventors:

Edward T. Armstrong - Butler NJ

Assignee:

TII Corporation - Lindenhurst NY

International Classification:

C02C 104

US Classification:

210151

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.

TII Corporation - Lindenhurst NY

International Classification:

B05B 306

US Classification:

239254

Abstract:

A rotary distributor arm comprising improved distribution nozzles and flow control accomplished by a gradual taper of the arm itself is defined which ensures a uniform flow distribution across the full radius of the distributing medium so that uniformity and optimum economy and efficiency are achieved with respect to the trickling filter itself because a uniform fluid flow is distributed across the entire top surface thereof.

Appl. No.:

5/531095

Inventors:

Edward T. Armstrong - Butler NJ

Assignee:

TII Corporation - Lindenhurst NY

International Classification:

C02B 308

US Classification:

210 62

Abstract:

The present invention relates to a two stage oxidative system for the disinfection of material which may contain nitrogen commonly in the form of ammonia or ammonium as in the treatment of waste or sewage plant effluent by adding a primary oxidizing agent to the effluent to disinfect as well as to lower the pH of the effluent and by adding a secondary oxidizing agent to produce a synergistic disinfection system in which the distribution of ammonium and ammonia is shifted to nearly all ammonium. A desirable pH level is 7 or less with desirable primary oxidizing agents including aluminum chloride or ferric chloride with desirable secondary oxidizing agents including chlorine, chlorine dioxide, ozone as in oxygen or air, or sodium hypochlorite. The invention further relates to an activated sludge aeration system in which desirably there are no stagnant areas and maximum diffusion is achieved, efficiently. The invention further relates to a continuous treatment of a fluid by chemical reaction with a treating fluid as in an in-line reactor.

US Classification:

Abstract:

An apparatus for dissolving at least one gas in a liquid comprises an eductor submerged in a liquid, desirably in combination with a high turbulence mixing device, so that synergistic results are obtained. The inlet portion of the eductor generally has an inward convergence towards a throat. The outlet portion of the eductor has an outward divergence. A diffuser which generally carries the gas mixed with a liquid extends through the eductor inlet portion and through the throat portion into the outlet portion. In a desired embodiment, the diffuser is connected or attached to a high turbulence mixing device such as desirably, a flat plate orifice in a conduit. An injection tube extends through the flat plate orifice downstream into the conduit pipe and injects a gas into the liquid to produce a gas-liquid mixture. The apparatus dissolves an exceedingly high amount of gas into a liquid and requires very low amounts of energy. In one aspect, the eductors may be placed vertically; in another aspect the eductors may be inclined within a tank, lagoon, and the like to impart a directed flow pattern thereto.
