Fidelity RO reverse osmosis water treatment equipment cosmetic
First, the reverse osmosis principle
RO reverse osmosis equipment using the most advanced, energy efficient membrane separation technology, reverse osmosis equipment, the principle is the role of osmotic pressure above the solution, to keep the other semi-permeable membrane through which substances can not be left to other substances and water. Reverse osmosis membrane pore size is very small, so reverse osmosis equipment can effectively remove water soluble salts, colloids, microorganisms, organic compounds such as, reverse osmosis equipment to produce pure water, high water, to meet the needs of different industries, different needs of users . When water and salt water is the ideal semi-permeable membrane separating the ideal semi-permeable membrane allows only water to prevent the passage of salt through, this time the water side of membrane water spontaneously flows through the salt water side of the semi-permeable membrane, a phenomenon known as for the infiltration of salt water in the membrane if the pressure side, then the water flow will be inhibited spontaneous slowed down, when the pressure reaches a certain value, the net flow of water through the membrane is equal to zero, the pressure is called osmotic pressure, when salt water side of the membrane applied pressure is greater than osmotic pressure, water will flow reversal, this time, saline water will flow into the water in the side, this phenomenon is the reverse osmosis water (RO) treatment of the basic principles.
Second, reverse osmosis About
RO (Reverse Osmosis) gauge difference is the use of reverse osmosis technology-driven membrane filtration technology, from the twentieth century, the United States Aerospace Science and Technology of the sixties, then gradually converted to civilian use, has been widely used in scientific research, medicine, Food, beverages, water desalination and other fields. RO reverse osmosis membrane of small pore size to nanometer (1 nanometer = 10-9 m), to a certain pressure, H2O molecules through RO membrane, while the source of water, inorganic salts, heavy metals, organic matter, colloids, bacteria, viruses, etc. RO membrane impurities can not, so the water can and can not concentrate through the water strictly separated. After the general tap water after the RO membrane filtration water conductivity 5
