It is easy to pollute water sources, but not easy to control water pollution. For many years, people have been fighting against water pollution, but water pollution still permeates into the safety loopholes of domestic water. In order to protect people's daily water safety, RO membrane began to be converted to civilian use. So, how does RO membrane filter impurities and purify domestic water? Reverse Osmosis Systems Supplier will explain to you.
RO membrane is a product created by people using wisdom after observing nature carefully. If dilute solution and concentrated solution are poured on both sides of a U-shaped tube and a semi-permeable membrane is placed in the middle, the dilute solution will flow to the concentrated solution side due to natural action. After stabilization, there will be a height difference between the two sides. This process is called infiltration. The pressure difference between the two sides is osmotic pressure.
Reverse osmosis process is to apply a pressure greater than the osmotic pressure on the concentrated solution side so that the concentrated solution can flow to the dilute solution side through the semi-permeable membrane. In this process, the solute in the concentrated solution will be blocked by the semi-permeable membrane on the concentrated water side. In RO membrane water purifier, semi-permeable membrane is RO membrane. Because the filtration accuracy of RO membrane reaches 0.0001 micron, it can filter silt, rust, suspended matter, colloid, bacteria, virus, metal ions, etc. in water, with good filtration effect and high effluent quality, which can be directly drunk.
Knowing the working principle of RO membrane, consumers can also conclude that to judge whether RO membrane is good or not, two factors can be understood, one is the size of membrane pores, the other is the size of membrane operating pressure.
