What are the working principles of household Ultrafiltration filters and Reverse Osmosis filters?

Household ultrafiltration filter is the principle of ultrafiltration and also a principle of membrane separation process.Ultrafiltration uses a pressure active membrane to trap colloids,particles and relatively high molecular weight substances in water under the action of external driving force(pressure).And the separation process of small solute particles through the membrane.


The working principle of the household RO filter is to apply a certain pressure to the water,so that water molecules and ionic mineral elements pass through the RO membrane,and most of the inorganic salts(including heavy metals),organic matter and Bacteria, viruses, etc. cannot pass through the reverse osmosis membrane, so that the permeated pure water and the impermeable concentrated water are strictly separated; the reverse osmosis water purifier is a machine that mainly uses the principle of reverse osmosis for water treatment.


RO water purifier is a machine equipment that mainly uses the principle of RO for water treatment.In this highly polluted living environment,RO water purifiers can efficiently purify sewage and provide us with clean and healthy water quality.
