20130334129 | COMPOSITE MATERIAL FOR PURIFICATION OF A LIQUID BY FILTRATION - The invention relates to composite materials, more specifically to composite membrane materials on the basis of polymeric materials used for the purification of a liquid, in particular drinking water. The novel composite material for the purification of a liquid by filtration is formed from a polymeric membrane in the form of a fibrillar-porous matrix comprising a hydrophilic polymer and a metallic antibacterial agent. The fibrillar-porous matrix comprises, at least in part of the volume thereof, stable active zones consisting of clusters of a metallic antibacterial agent in combination with molecules of hydrophilic polymer, wherein at least some of the clusters of metallic antibacterial agent are bonded to one another and to the surface of the pores of the matrix by means of the molecules of hydrophilic polymer, wherein at least some of the clusters of metallic antibacterial agent are additionally chemically bonded to the surface of the pores of the matrix, wherein the mean distance between the active zones is smaller than at least three times the mean diameter of the pores of the matrix. The technical result achieved using the invention consists in achieving stable hydrophilicity of the polymeric membrane during use thereof while at the same time maintaining the permeability of the polymeric membrane and increasing the bacteriostasis of the composite material. An additional technical result achieved using the invention consists in increasing the bacteriostasis of the juxtamembrane region during filtration of a liquid. | 12-19-2013 |
20130199974 | Device for Purifying a Liquid - A device for purifying a liquid is disclosed. The device includes a collecting vessel for an unpurified liquid, a collecting vessel for a purified liquid, a replaceable filter module filled with a filter material and an automatic means for timed injection of air into the collecting vessel for the unpurified liquid during a filtration process. The automatic means is connected to the collecting vessel for the unpurified liquid by an injection nozzle having a pressure control valve. Moreover, the automatic means is for maintaining positive air pressure above the unpurified liquid during the filtration process. Maintenance of positive air pressure during the filtration process increases filtration speed of the liquid with simultaneous increase in degree of purification of the liquid. | 08-08-2013 |
20120305474 | COMPOSITE MATERIAL - The invention relates to composite materials, and more particular to composite adsorptive materials for purification of liquids, in particular, a drinking water, on the basis of components of a granulated material and a fibrous material. The new composite material for filtering purifying a liquid on the basis of a mixture of components of granulated and fibrous materials comprises volume zones with adjustable density, which zones create the structure of the material, which structure is self-strengthened when a liquid flows in the course of filtration, wherein, said volume zones make the material most part, each zone is created in the form of a interlaced fiber site, which sites are bonded among themselves by separate fibers, and the space within and between said interlaced fiber sites is filled with a granulated material. | 12-06-2012 |
20120256417 | RAPID ASSEMBLY FLANGE JOINT - The invention relates to flange joint devices. The rapid assembly flange joint consists of a connecting device in the form of a constricting collar made up of at least two parts with a shaped groove on the concave face, said channel corresponding to the cross-section of the two coupled flanges of the members that are being connected, and clamping elements in the form of retaining sections on the flanges. The connecting device is provided with fasteners in the form of walls; the retaining sections are in the form of grooves, the width of which is not less than the thickness of the one or two fasteners that engage therewith. The number of grooves is not less than the number of component parts of the connecting device. The invention provides for a reliable connection between flanged cylindrical members without the need for additional fastening and clamping elements and without increasing the sizes of the connection point. | 10-11-2012 |
20120234739 | WATER PURIFICATION SYSTEM - The inventions relate to means for purifying water, primarily drinking water, and can be used in domestic water purification systems. The claimed filtered water storage unit for the storage device of a water purification system comprises a housing, an elastic chamber disposed therein for filtered water, and a region for pressurizing untreated water, which is defined between the wall of the chamber and the wall of the housing. The elastic chamber is made of a modified biaxially oriented thermoplastic elastomer and consists of a chamber body and neck, formed as a single piece, the neck being rigidly secured in the housing. The water purification system comprises a reverse osmosis membrane, a clean water discharge pipe, an overflow into a drain, a clean water tap, and a storage device comprising a filtered water storage unit and a hydro-automatic unit. In a first embodiment of a system with a storage device, the outlet of the controlled chamber of a valve for controlling pressurization of the water is associated with the water pressurizing region in the housing of the water storage unit, and the input of the controlling chamber of a valve for controlling drainage is associated with the clean water discharge pipe upstream of the tap, wherein the valve for controlling pressurization of the water is normally open and the valve for controlling drainage is normally closed. The claimed water purification system is highly reliable and provides a high quality of purified water. | 09-20-2012 |
