Description

Sealed filter core of full carousel formula of RO membrane pure water export

Technical Field

The utility model relates to the technical field of filter elements, in particular to a full-rotating-disc type sealed filter element of an RO (reverse osmosis) membrane pure water outlet.

Background

RO chinese means reverse osmosis. In general, water flows from a low concentration to a high concentration, and after the water is pressurized, the water flows from the high concentration to the low concentration, i.e., the so-called reverse osmosis principle: because the pore diameter of the RO membrane is one million (0.0001 micron) of hair, bacteria and viruses can not be seen by naked eyes, and the number of the bacteria and the viruses is 5000 times that of the hair, only water molecules and partial mineral ions can pass through (the passing ions have no beneficial loss orientation), and other impurities and heavy metals are all discharged from the waste water pipe. All seawater desalination processes and spaceman wastewater recovery treatment are adopted, so the RO membrane is also called as an external high-tech 'artificial kidney'. Top-grade RO membranes are adopted for polymer filtration in the fields of medical, military and civil at home and abroad. Reverse osmosis is a new membrane separation technology developed in the 60 s, and is a process of separating a solvent from a solute in a solution under pressure by means of a reverse osmosis membrane.
