The structure of a water purifier includes many components that are assembled and designed modernly. In general, for a water purifier to function well, it must have a good structure.
What is the concept of RO water purifier?
RO water purifier (RO stands for REVERSE OSMOSIS) is a device that utilizes advanced RO filtration technology. It aims to eliminate all impurities such as: Sediments, pesticides, harmful bacteria. Additionally, the water purifier helps to supplement the body with beneficial minerals. Providing you and your family with clean and safe water.
Basic schematic diagram of RO water purifier structure
Our understanding of the diagram of RO water purifier is as follows:
- First: To operate the RO water purifier, we need to connect the water pipe from the machine to the inside of the container. Then install an additional water supply valve to adjust or cut off the water supply when needed.
- Second: Then we install 3 filter cores including cores 1, 2, and 3 in the correct position in the purifier cabinet.
+ Using a low-pressure valve, solenoid valve along with a pressure pump between core 1 and filter core 2.
+ The low-pressure valve will help us measure the input water pressure. If the input water pressure is not strong enough, the machine will stop and not operate. Because according to the standard, the input water pressure must be from 3m or above. As for the solenoid valve, it will automatically open and close and control the quality of the flow.
- Third: Connect the RO wire into the head of filter core 1. When connecting, you need to wrap additional sealing tape and tighten the screws. This ensures that water does not leak into the RO membrane.
- Fourth: Finally, install the functional cores and RO purifier pressure tank.
What is the structure of an RO water purifier?
You can easily notice that RO water purifiers consist of 2 main components:
- Water filter system.
- Some accompanying accessories and parts.
1. RO water filter system
A standard RO water purifier usually has 5 filter stages. And will be supplemented depending on the quality of each water filter stage as well as the needs of users.
- Stages 1 to 3: These are typical coarse filter stages to filter rust, organic impurities, sediments. It can also filter dissolved fats, algae, and stick insects, etc.
- Stage 4: This is the most important filter stage of the RO water purifier. This is the stage through the RO membrane. With a membrane with ultra-small pore size, only water molecules can pass through. While organic impurities, heavy metals, bacteria, etc., will be retained and discharged through the waste water route.
- Stage 5: This stage stabilizes sweetness and increases the pH of drinking water.
2. RO water purifier accessories and parts
Depending on the different types of water purifiers, the accessories may vary slightly. Here are some common accessories that will usually come with an RO water purifier:
- Faucet: There are many types of faucets with different qualities.
- Solenoid valve: This is an electrically operated valve that separates free-flowing permeate water.
- Low-pressure valve: This valve interrupts the circuit when the water supply is weak or runs out of water.
- High-pressure valve: This valve controls the operation of the purifier. When the pressure tank has enough water, the high-pressure valve will automatically cut off the power.
- Waste water valve: This valve is responsible for discharging waste water from the RO membrane.
- Pump: It pumps water and creates high water pressure to push through the RO membrane filter.
- Pressure tank: It stores water and provides pressure to the system.
Conclusion
In the above article, we have provided you with diagrams and structures of RO water purifiers. RO water purifiers are indeed excellent devices that help protect people's health. If you still don't own an RO water purifier, then buy one now. You will be very satisfied with the advantages it brings.
