The outer antibacterial pp cotton filter middle activated carbon filter inner layer composite ultrafiltration membrane filter

Becomes more and more popular at present, it is well known that water purifier, water purifier filter is used in a variety, from single stage filter to multilevel filter, including antibacterial pp cotton filter, activated carbon filter and ultrafiltration membrane filter, multi-stage grading filter implementation, using single antibacterial pp cotton filter device, single active carbon filter device, single ultrafiltration membrane filter device to multi-stage purification of water, so the overall design is more complex, need more equipment. In order to overcome the multi-stage single-stage filter equipment, covers an area of big, this invention will antibacterial PP cotton filter, activated carbon filter, ultrafiltration membrane filter of multilevel filter improvement for single outer layer activated carbon antibacterial polypropylene cotton filter lining for composite ultrafiltration membrane filter. Activated carbon filter sets in antibacterial polypropylene cotton filter, and then the water end of ultrafiltration membrane filter to set within the tubular spacer, then puts the activated carbon filter, adopting integrated composite design of tap water by antibacterial polypropylene cotton filter outer filter, then through middle filter filter, activated carbon filter and then into the ultrafiltration membrane filter element inner layer filter into water again. Tap water, first of all, through the outer layer of the antibacterial PP cotton filter, and then through the middle into its internal surface activated carbon filter, and then through the inlet opening of ultrafiltration membrane filter on the inner wall and casing, tubular spacer at the end of the inlet into the interior of the ultrafiltration membrane filament, then purified water from the tube end cover set of ultrafiltration membrane filament inside out.
