| 20090039009 | DISTRIBUTOR PLATES FOR COMPOSITE PRESSURE VESSEL ASSEMBLIES AND METHODS - The present invention provides: a distributor plate for a composite pressure vessel. The distributor plate includes a thermoplastic polymeric disk having a top side, a bottom side, a perimeter edge and a central opening. Radial slits are formed in the disk to define fluid flow passages through the disk between the central opening and the perimeter edge. The fluid flow passages through the disk are adapted to swirl fluid flowing through the disk from the bottom side to the top side around the central opening. The present invention also provides a water treatment vessel that includes one or more distributor plates, a method for manufacturing a composite pressure vessel that includes one or more of the distributor plates and a method for preparing a composite pressure vessel that includes one or more of the distributor plate for use as a water treatment apparatus. | 02-12-2009 |
| 20090127181 | METHOD AND APPARATUS FOR WATER RESTORATION - A treatment tank for treating waste water or other liquid is provided. The treatment tank has an interior cavity of the treatment tank, a liquid introduction system for introducing a liquid to be treated, into a top end of the treatment tank, an exit aperture for removing liquid from a bottom end of the treatment tank and a plurality of removable layers of filter media. The removable layers of filter media are spaced substantially vertically in the treatment tank between the top end of the treatment tank and the bottom end of the treatment tank. Each layer of filter media has a permeable sheet adjacent a bottom surface of the layer of filter media, the permeable sheet allowing liquid to pass through the permeable sheet but preventing filter media in the layer of filter media from passing through the permeable sheet. | 05-21-2009 |
| 20110056880 | SYSTEM FOR STIFFENING THE PLATES OF A LARGE-DIAMETER MULTI-STAGE COLUMN - Device for stiffening the plates of a multi-stage column with a diameter of more than 2 meters, whereby each plate supports a particle bed and the flow of at least one fluid passes through it from top to bottom, whereby said device consists of a number of beams that are located under the plate in question, each beam having a lower surface that is shaped like a triangle. | 03-10-2011 |
| 20110303602 | DEVICE FOR DISTRIBUTING FLUIDS IN A SIMULATED MOVING BED COLUMN WITH A LIMITED DEGREE OF IMMERSION WITHIN THE GRANULAR BED - The present invention describes a device for the distribution of fluids in a multi-stage column operating in simulated moving bed (SMB) mode comprising, in the direction of flow of the principal fluid, a distribution system ( | 12-15-2011 |
| 20130126412 | DOWNFLOW DENITRIFICATION SYSTEM - In general, the present invention is directed to systems for treating water or wastewater. In accordance with some embodiments of the present invention, the system may utilize a vessel with a plurality of filter beds, at least one inlet, and at least one outlet, and the system may include: a first filtration bed comprising a first granular and/or angular media, the first media having a high surface area and configured for biological and physical treatment of the water or wastewater; a second filtration bed including a second granular and/or angular media, the second media having a lower surface area than the first media; wherein the water or wastewater enters the vessel via the at least one inlet, flows through the first filtration bed and the second filtration bed, and exits the vessel through the at least one outlet. | 05-23-2013 |
| 20140042075 | SCALE INHIBITOR - The present invention provides a combined scale inhibitor and scale inhibiting device. The combined scale inhibitor contains organophosphorus filter materials, ceramic filter materials and polyphosphate filter materials. The organophosphorus filter materials are the granular filter materials of liquid organophosphorus scale and corrosion inhibitor while the said ceramic filter materials are the granular filter materials containing oxide ceramic powder. The said scale inhibiting device is comprised of a tank, a water inlet, a water outlet, an organophosphorus filter material layer, a ceramic filter material layer and a polyphosphate filter material layer in the said tank. The said organophosphorus filter material layer contains organophosphorus filter materials, which are the granular filter materials of liquid organophosphorus scale and corrosion inhibitor. The said ceramic filter material layer contains ceramic filter materials, which are the granular filter materials containing oxide ceramic powder. | 02-13-2014 |
