| 20110049043 | INSERTION-POINT SEAL FOR SPIRAL WOUND MODULE - An improved method of fabricating a spiral wound module seals a juncture between each scroll face, preferably a smooth, trimmed scroll face, and a central permeate tube. The tube is generally perpendicular to the scroll face. Modules produced using the improved method have fewer insertion point leaks than those produced without using the improved method. Fast curable cyanoacrylate adhesive is used preferably. | 03-03-2011 |
| 20110168623 | FEED SIDE PASSAGE MATERIAL AND SPIRAL SEPARATION MEMBRANE ELEMENT - A feed side passage material is provided in which sufficient antibacterial activity is obtained even in the spaces among constituent yarns and which hence can effectively prevent biofouling. Also provided is a spiral separation-membrane element employing the feed side passage material. The feed side passage material, which is for use in a spiral separation-membrane element, is a feed side passage material in a net form constituted of yarns (1 and 2) containing a chlorophenol compound antibacterial. The spiral separation-membrane element comprises a perforated hollow core tube and, wound therearound, one or more separation membranes, one or more feed side passage materials, and one or more permeate side passage materials. The element is characterized in that the feed side passage materials each is said feed side passage material. | 07-14-2011 |
| 20110174725 | FILTER MODULE AND PROCESS FOR MANUFACTURE OF SAME - A filter module comprises a body of wound layers of a sheet material, said body having inner and outer peripheral surfaces, a winding axis and a passage along the winding axis and in fluid communication with the inner peripheral surface, the sheet material having openings forming two channel types from the inner to the outer peripheral surfaces, a first channel type open at the outer peripheral surface and closed adjacent to the inner peripheral surface, a second channel type open at the inner peripheral surface, in fluid communication with the passage and closed adjacent to the outer peripheral surface, the two channel types separated from each other by sheet material, one channel type being inlet channels communicating with an inlet, the other channel type being outlet channels communicating with an outlet, the edge of the inlet channel openings having a thickness less than the thickness remote from those openings. | 07-21-2011 |
| 20110272344 | Non clogging screen - A filter assembly includes a filtering screen having a top surface and a bottom surface. A skeletal structure is attached to the filtering screen and has a top surface and a bottom surface. The bottom surface of the filtering screen contacts the top surface of the skeletal structure. The skeletal structure forms a plurality of downward extending channels. | 11-10-2011 |
| 20120037562 | EDGE MEMBER FOR MEMBRANE ELEMENT AND MEMBRANE ELEMENT EQUIPPED WITH SAME - Disclosed are an edge member for membrane elements that can effectively improve adhesion with exterior finishing materials, and a membrane element that is equipped with the same. A plurality of types of undulations ( | 02-16-2012 |

| 20110186505 | FILTER MODULE AND PROCESS FOR MANUFACTURE OF SAME - The present invention provides a filter module comprising a body of wound layers of a sheet material, said body having an inner and an outer peripheral surface, a winding axis and a passage extending along the winding axis of said body and in fluid communication with said inner peripheral surface, said sheet material having a plurality of openings formed therein, said openings forming two types of channels within the wound layers of sheet material of said body, said channels extending in a direction from the inner peripheral surface to the outer peripheral surface, a first type of channels being open at one end at said outer peripheral surface of the body and closed at the other end located adjacent to said inner peripheral surface, a second type of channels being open at one end at said inner peripheral surface of the body, in fluid communication with said passage and closed at the other end located adjacent to said outer peripheral surface, said channels of the one type being separated from the channels of the other type by portions of sheet material, one of said types of channels being inlet channels communicating with a fluid inlet of said filter module, the other of said types of channels being outlet channels communicating with a fluid outlet of said filter module, wherein the surface of at least one type of the channels supports a precoat. The present invention further relates to a process for the manufacturing of a filter module according any one of claims | 08-04-2011 |
| 20140042080 | REVERSE OSMOSIS MEMBRANE ELEMENT - A reverse osmosis membrane element has a relatively high recovery rate. In the present invention, water ports of the reverse osmosis membrane element are located at both ends thereof, and a waterproof adhesive tape is coated between a flow guide net and a reverse osmosis membrane of the reverse osmosis membrane element, including a plurality of adhesive tapes parallel with an axial direction of the reverse osmosis membrane element, so that fed water is discharged from the water outlet after circuitously flowing between adjacent adhesive tapes along the axial direction of the reverse osmosis membrane element. In the technical solution of the present invention, a circuitous flow passage is available in the reverse osmosis membrane element, which increases the fluid flow rate, and decreases the surface pollution rate of the reverse osmosis membrane, thereby contributing to the improvement of the recovery rate of the reverse osmosis membrane element. | 02-13-2014 |
