Abstract: An ozone generating apparatus which comprises a plurality of chambers filled with an adsorbent, wherein a wet raw air is fed through one of the chambers filled with the adsorbent to adsorb moisture to form a dry air and the dry air is fed into an ozonizer to convert it into a dry ozone-containing air, and all or part of the dry ozone-containing air is fed into the other chamber filled with the adsorbent to purge water adsorbed on the adsorbent and to discharge it as a wet ozone containing air. The valves are then switched to feed the wet air to the other chamber filled with the adsorbent, whereby the moisture is adsorbed and the dry ozone-containing air fed from the ozonizer is fed into the former chamber filled with the adsorbent to reactivate the adsorbent and to discharge it as the wet ozone-containing air. The cycle is continuously repeated by switching valves.

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.The present invention also 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.Another aspect of the present invention relates to the nitrification of ammonia in the form of secondary effluent from a waste treatment system wherein the ammonia is converted to nitrates in a tertiary unit operation so that the effluent has low ammonia content.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.The invention further contemplates an injection-mixing system immersed in a contact tank utilizing efficient mixing devices for disinfection and a unique flowthrough arrangement into an influent conduit as well as through the contact tank whereby maximum dispersion of the disinfectant throughout the influent with maximum economy is achieved.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.The invention also relates to the efficient production of ozone by varying the oxygen feed rate, voltage, current or frequency or the ozone in oxygen concentration.The invention also relates to the enrichment of oxygen by adding air to a high-pressure holding tank containing a liquid in which oxygen is soluble, bleeding off nitrogen-rich gas and desorbing gas from the liquid at a lower pressure.

Abstract: A unique combination of one and preferably a pair of gas drying units for drying oxygen containing gas to be ozonized and a corona discharge ozone generating unit is provided by a vortex tube unit having an inlet for receiving dried air to be ozonized, a cool air outlet carrying the slow moving molecules of the gas to the inlet of the ozone generating unit and a warm air outlet connected through passageways extending to openings in the drying units for circulating warm air for drying saturated gas drying units. Where two drying units are provided, the air to be dried and ozonized is preferably alternately automatically fed to the inputs of the two drying units, and the warm air outlet of the vortex tube unit is alternately fed through the air drying unit so the drying unit which at a given instant is not receiving air to be dried is itself being dried by warm de-moisturizing air.

Abstract: THE INVENTION REPRESENTS A NEW CONCEPT IN LIQUID PROCESSING PARTICULARLY IN SEWAGE TREATMENT UTILIZING AIR, OXYGEN OR A CARRIER GAS WITH OZONE AS AN ATTENUATOR OF ANAEROBIC BIOTA, FOR GENERALIZED DISINFECTION, FO AERATION, OR FOR OXYGENATION. ESSENTIALLY, UNIQUE DESIGNS AND/OR PROCESSES ARE INCORPORATED INTO THE CONVENTIONAL SETTLING TANKS ASSOCIATED WITH SEWAGE TREATMENT, AS WELL AS IN THE BIOPROCESSES, ACTIVATED SLUDGE OR TRICKLING FILTER OPERATIONS. THE STRUCTURAL IMPROVEMENTS IN SETTLING REDUCE VELOCITY, INHIBIT BOUNDAY LAYER SEPARATION AND ACT TO SUPPRESS MIXING OF THE SEWAGE TO GREATLY ENHANCE SOLID AND FLUID SEPARATION, WHILE IN THE BIOPROCESSING OPERATIONS, THE KEY IS TO IMPROVE EFFICIENCY OF THE LIQUID-GAS EXCHANGE WHEREBY MUCH BETTER OXYGEN CONTACT IS ACHIEVED. THE LIQUID-GAS EXCHANGE FEATURE UTILIZES A HIGH MOMENTUM EXCHANGE UNDER TURBULENT FLOW CONDITIONS IN A HYDRAULIC PRESSURE GRADIENT TO ACHIEVE INTIMATE MIXING OF THE DESIRED GAS IN THE FLUID SO AS TO ACHIEVE THE DESIRED VERY RELIABLE AND EFFICIENT LIQUID-GAS EXCHANGE.

Abstract: A continuous reaction is effected in a gas stream by an electric discharge at a point in the stream where the flow has been made supersonic and the pressure and temperature lowered by a substantially adiabatic expansion. Various forms of apparatus for carrying out such a process are described. The apparatus may be used for the production of ozone which is used to convert ethylene and tetramethyl-ethylene fed into the apparatus into the corresponding ozonides. On leaving the apparatus the ozonides are converted in the presence of water into formaldehyde and acetone respectively.ALSO:A continuous reaction is effected in a gas stream by an electric discharge at a point in the stream where the flow has been made supersonic and the pressure and temperature lowered by a substantially adiabatic expansion. One form of apparatus, Fig. 1, comprises a supersonic nozzle 1, a pressure reducing chamber 17 for starting the action of the nozzle and a recompression chamber 13. Gas from an inlet pipe 6 passes along a cylindrical chamber 5 to a convergent part 2 of the nozzle 1 and then expands in a divergent part 4. A hollow electrode 8 supported by insulators 9 and 10 in the chamber 5 produces a discharge at the outlet 7 of the nozzle 1. The recompression chamber 13 comprises a convergent part 14, a cylindrical part 15 and a divergent part 16. This apparatus may be used for the production of acetylene and hydrogen from methane gas, or for the cracking of other hydrocarbons. An alternative form of apparatus is described in which the electrode 8 is extended to the part 16 of the chamber 13 and is closed at the end, but is provided with side vents for the injection of methane into the part 15 of the chamber 13. Two discharges are set up, the first at the end of the nozzle 1 for producing ozone, and the second in the chamber 13 for partially oxidizing the methane.
