Pure water equipment mainly uses reverse osmosis membrane technology. Its working principle is to exert a certain pressure on water, allowing water molecules and ionic mineral elements to pass through the reverse osmosis membrane, while most of the inorganic salts dissolved in the water, including heavy metals, organic matter, bacteria and viruses, cannot pass through it. Through the reverse osmosis membrane, the permeated pure water and the impermeable concentrated water are strictly separated. The pore size on the reverse osmosis membrane is only microns, while the diameter of viruses is generally microns, and the diameter of ordinary bacteria is There are micrometers in diameter.
