| 20080223797 | FILTERS WITH IMPROVED MEDIA UTILIZATION AND METHODS OF MAKING AND USING SAME - Multi-core solid profile filter media blocks include multiple sub-blocks, which may be formed by providing a block with multiple interior cavities extending deep into the block, to allow water to flow deep inside the filter block to access the media of the sub-block (in the case wherein the cavities are at the inlet to the block) or that allows water to be collected from each filtration sub-block (in the case wherein the cavities are at the outlet from the block). One or more indentations/spaces/gaps in the exterior surface of the block also may be provided to separate and extend between portions of the sub-blocks, so that substantially all of the filter media of a sub-block is accessible to fluid for filtration. This way, a filter block may include a large amount of media in a small cartridge or package volume, and the filter block may exhibit good flow distribution and low pressure drop. Sub-blocks of the filter block may be integrally formed together into the filter block, or may be directly connected, for example, preferably without any housing or internals clamping or fastening the sub-blocks together. | 09-18-2008 |
| 20110031195 | System and Method for Recirculating/Filtering/Flushing a Water Main - A recirculating/filtering/flushing system for cleaning a water main is provided, wherein the water main includes first and second access points. The system comprises at least one filter for filtering water in the water main; an inlet conduit coupled with the first access point and the at least one filter; an outlet conduit coupled with the second access point and the at least one filter; a bypass conduit coupled with the inlet conduit at a first location upstream of the at least one filter, and coupled with the outlet conduit at a second location downstream of the at least one filter; and a pumping device for flowing the water in the water main through the inlet conduit, through either the at least one filter or the bypass conduit, and through the outlet conduit. | 02-10-2011 |
| 20110056894 | METHOD AND SYSTEM FOR FILTERING WATER, IN PARTICULAR, AN ULTRAFILTRATION METHOD - A water-filtering method has effectiveness and reduced contamination, and is in particular an ultrafiltration method, and a filtration system contains a plurality of individual filtration modules, each of which is supplied with untreated water via at least one untreated water inlet, and whose filtrate is removed via a filtrate outlet. The filtration modules are backwashed with filtrate, and are divided into groups, wherein during backwashing, each group is individually separated from the untreated water inflow and rinsed with the filtrate that is produced by the remaining groups and fed back during the backwashing. | 03-10-2011 |
| 20120175318 | REMOVAL DEVICE FOR MICRO-BUBBLES AND DIRT - A removal device for removing gas bubbles and/or dirt particles from a liquid in a conduit system includes a housing ( | 07-12-2012 |
| 20120181238 | WATER TREATMENT SYSTEM - A water treatment system can be essentially non-electric, and can use gravity to produce water that is safe for drinking. By such a system there can be provided a low cost, reliable way to treat water that is contaminated by water borne pathogens, to reduce or eliminate such contaminants to a safe level, and thereby produce water that is drinkable. | 07-19-2012 |
| 20120285901 | Filter with Tri-Flow Path Combinations - A filter includes a plurality of annular filter elements arranged in axially staggered relation. An axial flow path includes a plurality of flow path segments, some being filtered by a respective filter element, and others bypassing a respective filter element. Various combinations are provided. | 11-15-2012 |
| 20120285902 | Filter with Shaped Flow Path Combinations - A filter includes a plurality of annular filter elements arranged in axially staggered relation. An axial flow path includes a plurality of flow path segments, some being filtered by a respective filter element, and others bypassing a respective filter element. Various combinations are provided. | 11-15-2012 |
| 20130056426 | INFILTRATION/INFLOW CONTROL FOR MEMBRANE BIOREACTOR - A method and system for wastewater treatment comprising a first treatment zone ( | 03-07-2013 |
| 20130306577 | SEPARATOR FOR SEPARATING A LIGHT LIQUID-WATER MIXTURE AND METHOD FOR SEPARATING A LIGHT LIQUID-WATER MIXTURE - A separator is indicated, which is arranged in a container having a circular or ellipsoidal cross section and having a container wall, for separating a light liquid-water mixture, for example oil-polluted water, comprising: a feed arranged on a first side of the container having a feed chicane, which directs the supplied mixture downward and divides it into two first flow parts that are substantially of equal size, an outlet having an outlet tube, a circular or ellipsoidal flow wall having an internal wall side and an external wall side, wherein the flow wall passes through at least half of a full circle, preferably at least three quarters of a full circle, and has an opening, which is facing a second side of the container opposite the feed, wherein the flow wall between the external wall side of the flow wall and the container wall forms two flow channels at two opposite sides of the container wall in each case from the feed to the second side of the container, wherein in the flow channels in each case one of the two first flow parts is conducted from the feed to the second side of the container along the container wall, wherein the two first flow parts at the second side of the container having substantially opposite directions of flow meet one another and are reunited, and hole elements arranged in the two flow channels through which the two first flow parts flow. | 11-21-2013 |
