Abstract: A contact body for liquid and gas, primarily for cooling towers, the body comprising at least two separate contact body packs supported one upon the other and defining an interface therebetween, the packs each being formed of a plurality of formed sheets positioned in contact with each other and defining passages therebetween. The packs are positioned such that their sheets extend at an angle to one another; the sheets in the packs each having edge portions at the interface, and selected sheets in each pack having their edge portions at the interface offset with respect to the remaining sheets, whereby enlarged passageway segments are formed at the interface.

Abstract: A mobile water treatment plant capable of handling a high volume of sewage confined within the dimensions of a conventional truck-hauled container comprises:(1) a screen to separate gross solids from liquids;(2) a holding chamber between features 1 and 2 in which the liquid is aerated;(3) a flocculating chamber for the liquid;(4) a lamellar separator (bottom fed with intermediate auxillary lamellae extending 1/2 to 1/3 of the length of the main lamellae); and(5) treatment of the water from the lamellar separator with "activated oxygen" as described and claimed in U.S. Pat. No. 4,214,962.A preferred subsidiary feature is to recycle a controlled amount of the sludge separated at point 1 to the holding tank.

Abstract: A gas/liquid fill assembly for use in an evaporative cooling tower, chemical scrubbing apparatus or other device includes a plurality of facially-opposed corrugated sheets of material disposed in a substantially vertical, parallel relationship. The corrugations of each sheet are disposed at an angle to the horizontal with each of the corrugations extending continuously in substantially straight lines from one edge of the sheets to another edge. The corrugations in alternate sheets cross the corrugations in the sheets disposed between the alternate sheets. Adjacent corrugated sheets form channels to allow a gas and gravitating liquid to pass through the fill assembly. The sheets are formed of a foraminous material comprising an open-mesh network of interconnected webs. The interconnected webs are arranged to define a plurality of polygonally shaped openings.

Abstract: A splash bar fill assembly for a splash-type cooling tower includes a plurality of splash bars, each of which includes a one piece elongated member having a pair of upwardly converging leg members joined together to form an apex, and a vertical supporting rib member extending downwardly from the apex. The fill assembly also includes a wire mesh support system for the splash bars. The wire mesh supports the splash bars within the cooling tower in an arrangement of successive rows. Each row of the arrangement has its splash bars arranged in parallel and in spaced apart relationship. The splash bars of one row are disposed angularly to those of an adjacent row and are arranged parallel to and vertically offset from those of an alternate row. The wire mesh is formed from a plurality of vertical and horizontal wires which are joined together at their points of intersection.

Abstract: A drainage collection system for use in an evaporative cooling tower is disposed transversely within a cooling tower below a gas/liquid heat exchanging contact body to receive liquid gravitating therefrom and to collect the same. The drainage collection system includes a plurality of liquid collection plates which are arranged in parallel and inclined from the vertical. Each of the plates includes an upper and a lower end portion with the upper end portion of each overlapping the lower end portion of a respectively adjacent plate. Each plate is shaped over its central portion to form substantially planar upper and lower sections. The lower section is inclined less from the vertical than the upper section. The lower end portion of each of the plates is shaped to form primary and secondary collecting channels extending substantially across the width of the plate for collecting liquid directed thereto by the plate.

Abstract: An improved liquid gas contact tower of the type having film fill placed in the tower with its principal plane inclined at an angle to the vertical so as to intersect a gas path extending between gas inlet and outlet openings includes a plurality of dewatering sheets secured to the film fill adjacent its lower surface to intercept liquid collecting and flowing along the film fill sheets and deflect it away from the fill, thereby to decrease the air pressure drop through the film fill during use.

Abstract: An apparatus for equalization of overflow water and urban runoff in receiving bodies of water is disclosed. A tank separated from the body of water is arranged so that the tank volume or parts thereof are alternatingly filled by polluted water and by water from said body of water. This tank is formed by generally vertical walls extending from the surface of the body of water to its bottom and is divided into a series of compartments by means of similar intermediate walls. The compartments are in communication in sequence through apertures in the intermediate walls. A first compartment communicates with an inlet for polluted water, and a last compartment communicates with the body of water surrounding the tank.

Abstract: A reactor column is disclosed which consists of a plurality of blocks of contact body material formed of cross-corrugated sheets, with the blocks being stacked one upon the other in superimposed relation to define a column having sides and upper and lower ends. A plastic film is wrapped about the sides of the column and tightly engaged therewith to form a self-supporting reactor column suitable for use in distillation processes.

Abstract: A method of quenching coke and scrubbing the resulting gases is disclosed in which a supply of hot coke is placed in an enclosed tower having an open top and subjected to water deposited on it from above. The water is first passed through at least one layer of a liquid gas contact body formed of corrugated sheets of material arranged with the corrugations in each adjacent sheet crossing each other. This water passes in countercurrent relation to the gases rising from the quenched coke and, as a result, particulate matter, liquid drops and water-soluble vapors in the gases are removed in the contact body. The gases passing from the contact body are then passed through a mist-eliminator structure to remove water droplets therefrom.

Abstract: An apparatus for producing a corrugated sheet from a web of deformable material, for use in cooling towers and the like, includes an endless conveyor which is adapted to move along a predetermined path of travel and on which are mounted a plurality of web molding trays. The trays have a plurality of corrugations formed therein extending generally transversely of the path of travel and means are provided for selectively locking the trays on the conveyor with the corrugations located at predetermined acute angles with respect to the path of travel of the conveyor so that the angle of the corrugations formed in the web can be varied. An air knife arrangement is provided for urging the web against the corrugations in the trays to form the corrugations in the web.
