The Reverse Osmosis (RO) system is water treatment equipment that removes salts by means of semipermeable membranes under pressure difference. Opposite to natural osmosis, the process is defined as reverse osmosis. Utilizing the different osmotic pressures of various substances, RO systems can achieve separation, extraction, purification and concentration. Reverse osmosis can eliminate more than 97% of dissolved salts and over 99% of colloids, microorganisms, trace substances and organics in raw water. Advantages include low power consumption, no pollution, straightforward process, superior product water quality, and convenient operation and maintenance.
RO System Process Flow
Raw Water Pump → Quartz Sand Filter → Activated Carbon Filter → Water Softener → Security Filter → High Pressure Pump → Reverse Osmosis System → UV Sterilizer → Ozone Sterilizer → Product Water Tank
1. Raw Water Pump: Supplies operating pressure for quartz sand filter and activated carbon filter.
2. Quartz Sand Filter: Removes turbidity, suspended solids, colloids and organic matter.
3. Activated Carbon Filter: Eliminates color, free chlorine, organic substances and harmful contaminants.
4. Water Softener: Removes calcium and magnesium ions from raw water to reduce water hardness.
5. Security Filter: With 5μm filtration precision, it intercepts large particles such as iron fragments, dust, suspended solids and impurities, preventing them from entering and fouling the RO membrane; it also blocks most bacteria and viruses.
6. High Pressure Pump: Delivers high pressure (minimum 2.0 MPa) to the reverse osmosis system.
7. Reverse Osmosis System: The core unit of pure water treatment equipment. It achieves a salt rejection rate up to 99%, removing over 99% of ions, bacteria and particulates, as well as more than 98% of organics.
8. UV Sterilizer: Inactivates bacteria that may pass through the reverse osmosis system.
9. Ozone Sterilizer: Uses ozone to eradicate bacteria not eliminated by UV sterilization.
10. Product Water Tank: For storage of treated pure water.
Features: Primary desalination with salt rejection rate 95%–98%, lower investment and energy consumption.
1. Raw Water Booster Pump
Maintains constant system water supply pressure and provides sufficient water flow for subsequent systems.
2. Quartz Sand Filter
Mainly removes silt, rust, colloids, suspended solids, and other particles larger than 20 μm from raw water.
3. Activated Carbon Filter
Removes pigments, odors, and reduces residual nitrogen and other contaminants.
4. Resin Softening Filter
Adsorbs calcium and magnesium ions in the water, reducing hardness and preventing scale buildup.
5. Precision Filter
The precision filter is used to intercept small amounts of mechanical impurities that escape the pretreatment system. It contains a PP cotton filter element and filters particles as small as 5 μm to meet reverse osmosis feedwater requirements.
6. High-Pressure Pump
The primary and secondary high-pressure pumps provide pressure for the primary and secondary reverse osmosis systems, respectively.
7. Reverse Osmosis Membrane System
After reverse osmosis treatment, the impurity content in the water is reduced, improving water purity. Its desalination rate can reach over 97%, and it removes most bacteria, colloids, and high-molecular-weight organic matter.
8. Flowmeter
This allows you to clearly monitor the current pure water and brine flow rates, visually displaying the ratio of pure water to brine, facilitating system adjustments based on the desired ratio and output.
9. Pressure Gauge
This monitors the pressure differential across the membrane system, which is crucial during actual operation.
10. Electronic Control Unit/Online Instrument Display
The control cabinet uses a 24V transformer, ensuring safe voltage operation for all control components. Operation is intuitive, with indicator lights clearly indicating operating status. Internal wiring is neatly arranged, with each wire numbered, making the overall design easy to understand and operate.
