Description
Technical Field
The invention relates to the technical field of filters, in particular to an RO membrane filter.
Background
RO is an abbreviation for Reverse Osmosis in english, meaning Reverse Osmosis in chinese. 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-level RO membranes are adopted for polymer filtration in the fields of medicine, military and civil at home and abroad, and the existing water purifier filters all adopt multi-level filter elements, so that although the filter effect is good, non-professionals cannot replace the filter elements by themselves because the filter elements at all levels are connected by virtue of special adapters and pipelines; moreover, after a single array of special adapter and pipeline is used, their inner walls can't be washd to after the renew cartridge, at the rivers in-process, can cause the pollution to the filter core.
For ordinary multistage filter core, RO membrane filter has splendid filter capacity, need not multistage design, because aquatic contains certain calcium magnesium ion, when the RO membrane filters calcium magnesium ion for a long time, calcium magnesium ion can be stained with and attach in the RO membrane, lacks the dirty device that hinders dirt of effectively detaching aquatic calcium, magnesium ion in the RO membrane filter simultaneously, and the dirt that has calcium magnesium composition can make RO membrane filter be difficult to normal use.
To this end, an RO membrane filter is proposed.
