Reverse Osmosis (RO)
Reverse osmosis (RO) is a high-tech membrane separation technology developed in recent years. It has very small pore sizes, functioning as an ion-level separation device. It is now widely used in water desalination, salt removal, production of pure drinking water, and high-purity water. The separation targets are ions in solutions and small molecular weight organic compounds. It is a commonly used advanced device in pharmaceuticals, electronics, beverages, biology, medical engineering, environmental protection, and other fields.
Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle. At each suction nozzle, water flows rapidly from outside to inside in reverse, washing impurities attached to the inner wall of the filter screen into the suction nozzle, through the hollow shaft of the suction scanner, then discharged through the drain valve, completing the cleaning process which takes about 30-60 seconds. At this time, the pressure difference returns to normal, the cleaning process ends, and filtration resumes. During cleaning, the system continues to flow.

Overview:
Reverse Osmosis (RO) is a high-tech membrane separation technology developed in recent years. It has very small pore sizes, functioning as an ion-level separation device. It is now widely used for water desalination, salt removal, production of pure drinking water, and high-purity water. The separation targets are ions and small molecular weight organic compounds in solutions. It is a commonly used advanced device in pharmaceuticals, electronics, beverages, biology, medical engineering, environmental protection, and other fields.
Our factory produces reverse osmosis units based on advanced membrane modules imported from the United States, equipped with imported high-pressure stainless steel pumps, imported control instruments, high and low-pressure pipelines and valves, along with imported metering pumps for dosing and automatic cleaning equipment. Product specifications are based on output, ranging from 300 kilograms per hour to several hundred tons, with a complete range available. Reverse osmosis requires high-quality feed water, so pretreatment equipment must be well-prepared; please refer to the user manual for details.
Working Principle:
RO reverse osmosis technology is a high-tech water treatment method that relies on the characteristic of reverse osmosis membranes to separate solvents and solutes in a solution under pressure. "Osmosis" is a physical phenomenon; reverse osmosis applies pressure greater than natural osmosis to water containing salts and various fine impurities (raw water), causing water to move from the higher concentration side to the lower concentration side. Most fine impurities, organic substances, heavy metals, bacteria, viruses, and other harmful substances in the raw water are discharged through the concentrated water outlet.
Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle.
