Water purification system

Abstract

The invention relates to a water purification system. The water purification system comprises a water inlet pipeline, a pure water pipeline, a composite filter element and a reverse osmosis filter element; the composite filter element comprises a filter bottle and a composite filter element assembly arranged in the filter bottle, and a main water inlet, a secondary water inlet, a pure water outlet, a concentrated water outlet and an intermediate water outlet are formed in the filter bottle; an inlet of the reverse osmosis filter element is communicated with the intermediate water outlet, and a concentrated water outlet of the reverse osmosis filter element is communicated with the secondary water inlet; the composite filter element assembly comprises a front membrane group and a reverse osmosis membrane group, an inlet of the front membrane group is communicated with the main water inlet of the filter bottle, an outlet of the front membrane group is communicated with the intermediate water outlet, an inlet of the reverse osmosis membrane group is communicated with the secondary water inlet, and a concentrated water outlet of the reverse osmosis membrane group is communicated with the concentrated water outlet of the filter bottle; a pure water outlet of the reverse osmosis membrane group is communicated with the pure water outlet of the filter bottle; by operating the filter bottle, the front membrane group and the reverse osmosis membrane group can be dismounted and mounted together. According to the water purification system provided by the invention, the core replacement operation is simple, and the service life of the reverse osmosis filter core is prolonged.

Description

【Technical field】 [0001] The invention relates to the technical field of water treatment, in particular to a water purification system using a reverse osmosis filter element. 【Background technique】 [0002] As people's drinking water quality requirements are getting higher and higher, the use of reverse osmosis water purifiers is becoming more and more popular, and it has gradually become a commonly used product in households. The reverse osmosis water purifier mainly uses a reverse osmosis filter element for filtration, which can completely remove impurities such as heavy metal ions, organic matter, bacteria and viruses in the water, and provide safe and hygienic drinking water. In order to meet the drinking water requirements of the whole family, the requirements for the purified water flow rate of the water purifier are getting higher and higher. To achieve large-flow water purification, large-flux (above 200G) reverse osmosis water purifiers are generally used in the ma...

Problems solved by technology

However, the larger the flux of the reverse osmosis filter element, the larger the volume of the reverse osmosis filter element and the water purifier, and the higher the replacement cost of the reverse osmosis filter element.
