Description
Technical Field

Background
With the progress of scientific technology, the more the pure water flow of the reverse osmosis water purifier is, the more the whole machine flow exceeds 1200 gallons, the more and more the double reverse osmosis filter components are used for realizing the purpose of the ultra-large flow water purifier. At present, the main technical scheme adopted by the ultra-large flux water purifier using double reverse osmosis filter members is that the double reverse osmosis filter members are connected in series, the technical core is that the concentrated water of the first reverse osmosis filter member is the water inlet of the second reverse osmosis filter member, the pure water generated by the two reverse osmosis filter members is the pure water of the water purifier, and the concentrated water generated by the second reverse osmosis filter member is discharged.
However, the above water purifier has a very big disadvantage that the arrangement of the second reverse osmosis filter member at the downstream side with the concentrated water of the first reverse osmosis filter member as raw water makes the use condition of the second reverse osmosis filter member become extremely severe, thereby greatly shortening the life span thereof. In actual use, the service life of the second reverse osmosis filter element positioned at the downstream is only half that of the first reverse osmosis filter element positioned at the upstream, and if the replacement period of the first reverse osmosis filter element positioned at the upstream is six years, the replacement period of the second reverse osmosis filter element positioned at the downstream is only three years, so that the second reverse osmosis filter element is not friendly to consumers and service businesses, the consumers need to replace the second reverse osmosis filter element in advance, the use cost is increased, and the service business can increase the number of times of going up, so that inconvenience is caused.
