20160054076 | POLYMERIC COIL ASSEMBLY AND METHOD OF MAKING THE SAME - Coil assemblies for use in heat exchange applications are made using polymeric tubes, some with heat exchange and water redistribution media integral with the coil assembly and others with a water distribution subassembly integral with the coil assembly. One coil assembly includes at least two generally linear passes that are connected by return bends formed by folding an array of polymeric tubes. The passes have an array of at least two layers of polymeric tubes that pass through alignment holes in tube spacers only along the passes to maintain the tubes in substantially the same relative positional relationship to each other in the passes and in the return bends. Methods are explained for forming the coil assemblies and components, including the tube spacers and tube sheets to connect the coil assembly to inlet and outlet manifolds for the processing fluid flowing internally through the tubes. | 02-25-2016 |
20150211818 | COMPOSITE HANGER GRID AND COMPONENTS, SPLASH BAR, ASSEMBLY THEREOF AND METHOD OF ASSEMBLY - A composite hanger grid for supporting splash bars in a cooling tower uses separate vertical suspension members and horizontal beams by which all of the operational loads imposed on the splash bars are transferred to the horizontal beams, which then transfer the load to the vertical suspension members. Since all of the horizontal beams are independent of each other and separate components from the vertical suspension members, the horizontal beams will be loaded equally throughout the entire hanger grid. Also disclosed are components of the composite hanger grid, splash bars adapted for use with specific embodiments of the composite hanger grid, assemblies of the composite hanger grid with its supported splash bars, a method of assembling a composite hanger grid and a method of assembling an evaporative cooler fill assembly, including hanger grids and splash bars, in a cooling tower. | 07-30-2015 |
20150060346 | Hood for Preventing the Discharge of Debris from a Wastewater Collection Basin - An oil and debris separation hood mounts on the interior surface of a wastewater collection basin to cover the outlet opening and prevent hydrocarbons, debris and other pollutants from being discharged from the collection basin. The hood device includes a rounded body portion formed with a mounting flange extending along the back side of the hood device from a bottom edge and over the top portion. The upper portion of the hood device includes an access port closed by a sealable lid to provide access to the outlet pipe without removing the hood device from the collection basin. The top portion of the mounting flange is formed with a built-in vent opening that allows the pressure within the hood device to be equalized to the ambient air. The hood device can be formed from plastic sheet material through thermoforming techniques, and includes strengthening ribs and a hand grip. | 03-05-2015 |
20140053926 | Structured Sheet Cross-Flow Distribution Media - A structured sheet cross flow media is formed with a first corrugated sheet having corrugations defining flutes angled in a first direction, a second corrugated sheet defining flutes angled in a second direction, and an interstitial planar sheet disposed between the first and second corrugated sheets. The interstitial planar sheet traps the flow of fluid or gas, such as air, entering one end of the media block within opposing flutes until the end of the interstitial sheet is reached, whereupon the fluid or gas can disperse between the intersecting flutes of the first and second sheets to provide a controlled dispersal of the fluid or gas. In one embodiment, the interstitial sheet terminates at an intermediate height in the media block to define the width of dispersion of air bubbles entering at a single source point. | 02-27-2014 |
20130327728 | Process for Collecting Sediment from a Settling Tank - A method of removing sediment from the bottom of a settling collects the sediment from the compressed Zone IV layer of sediment adjacent the floor of the settling tank. The process utilizes a fabricated metal sludge collection system having a central truck and a pair of triangularly shaped header wings extending laterally to each side of the central truck. The header wings have an open throat that allows the passage of the Zone IV sediment layer into the header wing, while the diagonally oriented, rearwardly extending side edges of the header wing have elastomeric sweeps attached to prevent the sediment from passing out of the header wing. The sweeps accumulate the sediment at the rearwardly trailing apex of the header wing where a pump extracts the accumulated sediment remotely from the settling tank. A T-connector is formed with a baffle to improve the discharge of sediment from the header wings. | 12-12-2013 |
20130327707 | Drive Mechanism for Sludge Collection System - A sludge collection system operates in a submerged state at the bottom of a settling tank to remove sediment therefrom. The cable-driven sludge collection system utilizes a fabricated metal header wing formed in a triangular shape and connected to a central truck by a pivot pin. The header wings are supported on the floor of the settling tank by wheels to support the weight of the header wings. The front edge is open and unrestricted to allow the passage of the Zone IV sediment layer into the header wing, while the rearward, diagonally-oriented side edges of the header wings have elastomeric sweeps attached to prevent the sediment from passing out of the header wing and cause an accumulation of sediment at the rearward apex. The central truck includes pre-tensioned, spring-loaded connection plates for attachment to a cable drive mechanism for powering the movement of the truck and header wings. | 12-12-2013 |
20130327706 | Cable-Driven Submerged Sludge Collection System - A sludge collection system is mounted on the floor of a settling tank to remove sediment therefrom. The sludge collection system includes a pair of triangularly shaped header wings oriented with the apex at the rear. The front edge of the header wings are open to collect the sludge from the compressed zone along the floor of the settling tank while the rearward edges leading to the apex are provided with elastomeric sweeps to help move the collected sludge into the apex for removal therefrom. The header wings operate to consolidate the collected sludge into the apex where a pump extracts the sludge for discharge through flexible hoses. The connector combining the two hoses from the pumps incorporates an internal baffle to separate to two inlet ports through to the discharge port. The sludge collection system is moved along the floor of the settling tank by a cable drive mechanism. | 12-12-2013 |
20090071900 | Submerged Fixed Film Anoxic Bioreactor - A constant velocity serpentine anoxic reactor incorporates a multiple cell vertical serpentine path, as well as a horizontal serpentine path, through the anoxic chamber. A fixed film media is mounted within each cell of the anoxic chamber to provide a structure on which the bacteria can grow to sustain the biological reaction, which convert nitrates into nitrogen gas. The fixed film media can be a cross-flow media and can optionally include a web of textile material integrated within the fixed film media to enhance bacterial growth within the fixed film media or optionally the anoxic vertical serpentine configuration could be applied to an activated sludge operation. A nitrate recycle pump recycles about 75% of the effluent from the aerobic chamber back into the anoxic chamber to provide a nitrate source for the digestion of the BOD within the influent wastewater. | 03-19-2009 |
