The Principle of Reverse Osmosis System System Filter

The principle of the reverse osmosis system is very simple. It is to filter out impurities in the water through multiple filter materials to ensure the purity of the water entering the home. The current mainstream filter materials are as follows：

Polypropylene Sediment Filter

PP cotton is the pre filter of reverse osmosis system

This can be said to be the basic type of filter media, similar to the primary filter in an air purifier, which absorbs large particles through internal capillary fibers, which can effectively remove impurities with a particle size greater than 5 microns, such as sand, rust, and suspended matter. Its purification accuracy is not high, and its main function is to ensure the normal operation of the internal precision components. Generally speaking, the replacement of the pre filter of reverse osmosis system mainly depends on the color. If the filter material changes color, it means that the interior is saturated and needs to be replaced in time.

Activated carbon filter is mainly used to adsorb peculiar smell and pigment

Activated carbon filter of reverse osmosis system is mainly used to adsorb organic matter, odor and pigment, and its adsorption effect depends on the pore size of activated carbon. Most of the reverse osmosis system uses activated carbon particles in the second layer, also in order to ensure the normal filtering effect of the internal precision diaphragm. In addition, some water purifiers also use activated carbon in the innermost layer to further absorb the remaining odors in the purified water.

What is RO membrane?

The full name of RO membrane is reverse osmosis membrane. You may not believe it. It is a product of bionics, which is made by scientists imitating the membrane in seagulls. The pore size of the RO membrane is only 0.1 nanometers. Theoretically, 0.5 nanometers of water molecules cannot pass through, but under a certain pressure, water molecules can still "squeeze through". What the RO water purifier needs to do is to control this pressure. So that the water molecules can just pass but other ions can't pass, the pure water purification is realized.
