RO is the abbreviation of English Reverse Osmosis. The general flow of water is from low concentration to high concentration. Once the water is pressurized, it will flow from high concentration to low concentration, which is the so-called reverse osmosis principle: because the pore size of the RO membrane is one millionth of the hair (0.0001) Micrometers) are generally invisible to the naked eye. Bacteria and viruses are 5000 times larger. Therefore, only water molecules and some mineral ions can pass (the passing ions have no beneficial orientation), and other impurities and heavy metals are discharged from the waste water pipe. All seawater desalination processes and astronaut wastewater recovery and treatment use this method, so RO membranes are also known as high-tech "artificial kidneys" outside of the body. At home and abroad, in the medical, military and civilian fields, top RO membranes are used for polymer filtration.
Reverse osmosis is a new membrane separation technology developed in the 1960s. It is a process that relies on reverse osmosis membranes to separate solvents and solutes in solution under pressure. The full English name of reverse osmosis is "REVERSE OSMOSIS", abbreviated as "RO".

RO (Reverse Osmosis) reverse osmosis technology is a membrane separation and filtration technology that uses osmotic pressure difference as the power. It originated from the research of aerospace science and technology in the United States in the 1960s, and then gradually transformed into civilian use. It has been widely used in scientific research, medicine, and food. , Beverages, desalination and other fields.

The pore size of RO reverse osmosis membrane is as small as nanometers (1 nanometer = 10-9 meters). Under certain pressure, water molecules can pass through the RO membrane, while the source water contains inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses, etc. Impurities cannot pass through the RO membrane, so that pure water that is permeable and concentrated water that is impermeable are strictly distinguished.

The management of reverse osmosis equipment during shutdown, do you know what to do? Reverse osmosis equipment is a kind of water treatment equipment that utilizes a high-pressure pump to separate water molecules from a solution, which is widely used in industry, medical treatment, drinking and other fields. The advantage of reverse osmosis equipment is that it can effectively remove organic matter, inorganic matter, bacteria, viruses and other impurities in the water, and improve the quality and quantity of water. However, reverse osmosis equipment also has a disadvantage that it can not stop running for a long time, otherwise it will lead to the decline of the performance of the equipment, or even damage.

So, what matters do you need to pay attention to during the shutdown of reverse osmosis equipment? How to properly manage and maintain it? Today, I will share some professional knowledge and experience with you, and I hope it will help you.
