20090321344 | HEADER FOR FILTERING MEMBRANE MODULE AND FILTERING MEMBRANE MODULE USING THE SAME - A header for filtering membrane module and a filtering membrane module using the same is disclosed, which is capable of maximizing efficiency in power consumption by securing a constant flow of permeate through the use of a relatively-low negative pressure, the header for filtering membrane module comprising a body with a permeate collecting space therein; and a conduit at one end of the body, the conduit being in fluid communication with the permeate collecting space, wherein at least a portion of the permeate collecting space has an inclined shape. | 12-31-2009 |
20100078374 | ALIGNMENT APPARATUS FOR EXTERNAL PRESSURE TYPE MODULE AND FILTERING SYSTEM COMPRISING THE SAME - An alignment apparatus for external pressure type module and a filtering system comprising the same is disclosed, which is capable of supporting the external pressure type module while being connected to a pipe and the filtering system, wherein the alignment apparatus comprises a supporting member having a central through-hole into which the external pressure type module is to be inserted; and the filtering system comprises an external pressure type module, a pipe connected with the external pressure type module, and an alignment apparatus for supporting the external pressure type module while being connected with the pipe. | 04-01-2010 |
20120074056 | HOLLOW FIBER MEMBRANE MODULE, FILTRATION APPARATUS USING THE SAME, AND METHOD FOR MANUFACTURING THE FILTRATION APPARATUS - Disclosed are a hollow fiber membrane module, a filtration apparatus based on the same, and a method for manufacturing the filtration apparatus. The hollow fiber membrane module includes two headers respectively provided with a permeate collecting unit therein, wherein each of the headers has grooves on its two sides, the grooves being extended in a length direction of the hollow fiber membrane. Since one slide rod can simultaneously be inserted into grooves of two adjacent hollow fiber membrane modules, the hollow fiber membrane modules can mutually serve as guides for insertion/ejection thereof. Also, since the grooves formed on the header can serve as insertion holes into which a clamp is inserted, the clamp can be used for coupling between the hollow fiber membrane module and another element and reinforcement of the coupling. | 03-29-2012 |
20130213886 | SYSTEM AND METHOD FOR FILTRATION - Disclosed are system and method for filtration which can minimize the contamination of the filtering membrane through a pretreatment and perform the pretreatment and the filtration with a filtering membrane in a single filtering unit so that any need for separate and additional space and facility for the pretreatment can be obviated. The system for filtration of the present invention comprises a fine bubble supplier for providing fine bubbles into the feed water. The pretreatment is performed by supplying the feed water to be treated into the filtering unit through a dynamic filtration layer which is formed in the filtering unit as the fine bubbles rise. | 08-22-2013 |
20130291360 | HOLLOW FIBER MEMBRANE MODULE AND PULLER USED THEREFOR - A hollow fiber membrane module and a puller used therefore is disclosed, wherein each individual hollow fiber membrane module can be easily pulled out from a filtering apparatus provided with a plurality of hollow fiber membrane modules if it is required to be replaced or repaired.
