Embodiment
Term is explained
RO is English Reverse Osmosis membrane abbreviation, and Chinese means reverse osmosis.The flowing of general water
Mode is to flow to high concentration by low concentration, will be from high concentration flow to low concentration after water is once pressurize, that is, so-called reverse osmosis is former
Reason：Because the aperture of RO films is 5/1000000ths (0.0001 microns) of hairline, general naked eyes can not be seen, bacterium, disease
Poison is its 5000 times, and therefore, only hydrone and part can be by other impurity and a huge sum of money beneficial to the mineral ion of human body
Category is discharged by waste pipe.The process of all desalinizations, and spaceman's waste water recycling device use the method, therefore RO
Film is also known as external high-tech " artificial kidney ".
The present invention first core be to provide a kind of composite filter element and purifier, with reduce the synthesis of filter core into
This.
Hereinafter, embodiment is illustrated referring to the drawings.In addition, embodiments illustrated below is not to described in claim
The content of the invention rise any restriction effect.In addition, the full content of the composition represented by example below is not limited to as right
It is required that necessary to the solution of described invention.
Fig. 1 is referred to Fig. 2, wherein, the composite filter element of the embodiment of the present invention, including：
