| 20110006009 | ANTI-MICROBIAL MATRIX AND FILTRATION SYSTEM - Provided are an anti-microbial matrix and filtration systems containing the same. The matrix comprises a surface-modified inorganic component and a polymeric binder comprising particles having an irregular, convoluted surface. The surface-modified inorganic component comprises a reaction product of an anti-microbial component and an inorganic component. The anti-microbial component comprises a quaternary ammonium salt containing an epoxide group. A covalent bond is, for example, between the quaternary ammonium cation and a hydroxyl group of the inorganic component. The quaternary ammonium salt can be poly(methyldiallylamine epichlorohydrin). Further, the quaternary ammonium salt can have the formula according to I: (Formula I), wherein n is in the range of 5 to 24. The inorganic component can be diatomaceous earth. The polymeric binder can comprise ultra high molecular weight polyethylene (UHMW PE). Methods of making and using the same are also provided. | 01-13-2011 |
| 20110152054 | CIRCUMFERENTIALLY PLEATED FILTER ASSEMBLY AND METHOD OF FORMING THE SAME - A method of forming a filter element is disclosed comprising the steps of preparing a plurality of upstanding pleats each having first and second pleat legs, wherein the first pleat leg of one pleat is joined to the second pleat leg of a preceding pleat by a medial pleat section; moving the upstanding pleats into an overlapped condition wherein each medial pleat section becomes part of the second leg of a preceding pleat; and forming the overlapped pleats into a cylindrical configuration. | 06-23-2011 |
| 20110155661 | WATER FILTER MATERIALS AND WATER FILTERS CONTAINING A MIXTURE OF MICROPOROUS AND MESOPOROUS CARBON PARTICLES - A filter and filter material for providing or treating potable water is provided. The filter includes a housing having an inlet and an outlet, a filter material disposed within the housing, the filter material formed at least in part from a mixture of a plurality of mesoporous and microporous activated carbon particles. Preferably, at least some of the mesoporous activated carbon filter particles are coated with a cationic polymer, and even more preferably, at least some of the particles are coated with a cationic polymer and silver or a silver containing material. Kits comprising filters and information relating to the reduction, killing or removal of bacteria, viruses, microbials, and TTHM are also provided. | 06-30-2011 |
| 20110259812 | FILTER ELEMENT AND SEAL THEREFOR - A filter cell element for use in a housing to form a filtering assembly. The filter element has a media pack having an interior and a separator element having a passage therein for radial fluid communication between the media pack interior and an edge of the media pack. An overmold seal at the media pack edge seals the media pack to the separator element. Methods of making the filter element and methods of using are also disclosed. | 10-27-2011 |
| 20130304532 | SYSTEM AND METHOD FOR MAINTENANCE AND MONITORING OF FILTRATION SYSTEMS - A method is disclosed comprising retrieving information from a remote computer node including a database circuit. The database may store usage, status, and location information from a plurality of fluid monitoring apparatus for respective fluid treatment systems located at a respective customer site. It may be determined, from the information, whether at least one of the fluid treatment systems is in need of service. The method may include determining automatically whether one or more additional fluid treatment systems, located in a predefined area surrounding another fluid treatment system, is in need of service. The method may include generating, for display, a service plan for a service agent including a service route and location of one or more fluid treatment systems to be serviced, and indicating type of service or estimated duration of service to be performed on each fluid treatment system. | 11-14-2013 |
| 20130306552 | METHOD OF FORMING FILTER ELEMENTS - A method of forming a filter element is disclosed comprising introducing a mixture into a mold, the mixture comprising a plurality of susceptor particles and a plurality of polymeric binder particles. Eddy currents are induced in the susceptor particles by subjecting the mixture to a high-frequency electromagnetic field, the eddy currents being sufficient to elevate the temperature of the susceptor particles to cause adjacent polymeric binder particles to be heated to at least a softening point. The susceptor particles bind with the heated polymeric binder particles in the mold to form a coherent mass. The coherent mass is cooled to form the filter element. | 11-21-2013 |
| 20150068987 | FILTRATION SYSTEMS FOR FAUCETS - Fluid filtration systems that have openings in their sump closures are provided. Spouts for processed fluid may be added to direct flow of processed fluid. The spouts may be attached, permanently or removably, to the sump closures or to media cartridges. The system comprises: an inlet, an unprocessed fluid outlet, and a processed fluid outlet; a sump housing and a sump closure operatively associated therewith, the processed fluid outlet being located through the sump closure; a media cartridge located in the sump housing, the media cartridge providing processed fluid upon contact with unprocessed fluid; and a diverter. Flow of processed fluid may be directed through any desired angle when a rotatable structure is included in the system. Filtration systems may easily be cleaned and/or sanitized. | 03-12-2015 |
