摘要： An apparatus for treating water includes a vertically extending contact vessel, wherein water is contacted with ozone, and a return vessel which contains a column of water of a sufficient height to drive water through downstream filtering stages. Ozone is removed from the water and the rate of ozone injection is monitored and automatically adjusted so that no great amount of ozone remains in water entering the filtering stages. The ozone is generated in elongated elements that are cooled by the process water and that are positioned to serve as a static mixer for such water.

摘要： An underdrain assembly for a bed of filter media includes a plurality of elongated screen lateral elements which each have a generally flat bottom surface and a convexly curved upper surface which has flow openings therein. The lateral elements each have a width substantially greater than their height and include a means defining a generally tubular-shaped surface positioned internally thereof. The generally tubular-shaped surface includes flow distribution openings which have a total open area less than the total area of the flow openings in the curved upper surfaces of the lateral elements. In various embodiments, the generally tubular-shaped surfaces are shown as comprising a single tube, a plurality of tubes, and a tube defined by the portions of a plurality of adjacent channel-shaped members whose leg portions support the curved upper surface of the screen lateral elements.

摘要： Lateral member assembly for use in an underdrain lateral distribution system is made of plastics but is as capable as much heavier and more costly prior art metallic assemblies in supporting a bed of filter media which must be periodically backwashed with liquid and gas. Complementary elements, including a rigid extruded floor plate member having longitudinally extending side edge channels, and an overlying screen member having flange portions adapted to be retained by undercut recesses in the side edge channels, are adapted to be assembled to each other to form hollow lateral assemblies. In a preferred embodiment, the screen member is telescopically assembled to the floor plate member to cause the screen flange portions to interlock with the recesses in the side edge channels. The resulting assembly is sealed against leakage where the members are interlocked by a pair of flexible, integral plastic sealing strips which are co-extruded with the rigid floor plate member. In an alternative arrangement, the flange portions of the screen members engage a cam surface on the floor plate member which forces them away from each other as the screen member is pressed down against the floor plate member, thus causing them to snap into the undercut recesses in the side edge channels. The flange portions are then retained in a locked relationship with the floorplate member and sealed by flexible rod members forced into the space between the outside surfaces of the screen member and the outer walls of the side edge channels.

摘要： Underdrain lateral system, which is especially adapted for use in a gravity filter bed, includes, as its preferred embodiment, scallop-shaped laterals having an upper, wrapped wire, slotted screen surface. The screen surface supports and retains the filter media particles directly, without the necessity of an underlying gravel layer, and is itself supported by channel-shaped rod members which are welded to the wires. The web portions of the channel rods perform the function of simultaneously distributing air and water during backwashing, and include small apertures in upper channels and larger apertures in lower channels to cause a plenum to be formed inside the laterals which ensures that the distribution of air and water will be uniform throughout the lateral, even if the lateral is not perfectly level. Distribution of the air and water throughout all of the laterals is made even more uniform by mounting the laterals on a header and providing perforated flow tubes which extend from each lateral into the header to produce an additional air plenum therein.

摘要： Passive solar wire screens mount vertically on an edifice. The screens have rods vertically arranged parallel to one another and have wires horizontally arranged parallel to one another. The wires attach to the rods and have first surfaces facing away from the edifice in an upward direction from vertical. The wires also have second surfaces facing toward the edifice in a downward direction from vertical. When the sun has a summer elevation on the horizon, the first surfaces passively reflect solar energy incident thereto away from the wire screens. When the sun has a winter elevation on the horizon, however, the first surfaces passively reflect solar energy incident thereto toward the second surfaces, which in turn passively reflect the solar energy toward the edifice. A concave surface on the wires can also reflect thermal energy back to the edifice.

摘要： Improved flow modifier assembly for a water intake system having a cylindrical intake screen prevents damage to fish and other aquatic organisms by providing a controlled velocity profile which causes the average flow velocity to closely approach the peak flow velocity. By extending two or more concentric tubular flow modifiers into one end of the screen, it is possible to achieve flow uniformities of more than 90%, as compared to a maximum of about 72% for a prior art configuration utilizing a single tube flow modifier. In addition, the size, weight and cost of screen required can be greatly reduced for a given peak flow velocity as compared to prior art devices.
