An automatic reverse osmosis pure water machine with a pure water tank is a water purification device that can automatically produce and store pure water. It is widely used in households, laboratories, and some industrial fields. Here is an introduction to its working principle, components, and features:
Working Principle
The machine first passes the raw water through a series of pre-treatment filters. Typically, it includes a 5-micron PP melt – blown filter element to remove suspended solids larger than 5 microns, a granular activated carbon filter to adsorb odors, residual chlorine, and organic matter, and a 1-micron PP filter to further remove smaller suspended solids. Then, the pre-treated water is pressurized by a high-pressure pump and enters the reverse osmosis membrane. The reverse osmosis membrane has an extremely small pore size of about 0.0001 microns, which can intercept most impurities such as dissolved salts, bacteria, and viruses. Pure water passes through the membrane and enters the pure water tank for storage, while concentrated water containing impurities is discharged.
Main Components
- Pre-treatment System: In addition to the PP melt – blown filter element and activated carbon filter mentioned above, it may also include a sediment filter to remove larger particles of sediment and a scale inhibitor dosing device to prevent scale formation on the reverse osmosis membrane.
- Reverse Osmosis Unit: This is the core component, consisting of a reverse osmosis membrane and a pressure vessel. The reverse osmosis membrane is the key to separating pure water from impurities, and the pressure vessel provides a sealed space for the membrane operation.
- Pure Water Tank: Used to store the produced pure water, and its capacity can be selected according to different needs, such as 10L, 20L, etc.
- Control System: It usually adopts a microcomputer control system to automatically monitor and control the operation of the machine. For example, when the water level in the pure water tank is low, the system automatically starts to produce water; when the water tank is full or the raw water pressure is low, it automatically stops.
Features
- Automatic Operation: The whole process from water intake, purification to water storage is automatically completed, without the need for manual operation, which is convenient and quick.
- High – quality Water Production: It can effectively remove various impurities in the water, with a high ion interception rate, generally reaching 97% – 99%. The produced pure water can meet the drinking water standard and the water quality requirements of some high – precision fields such as laboratories.
- Convenient Water Use: There is a pure water tank for water storage, which can provide a relatively large amount of pure water at one time, meeting the needs of users for large – flow water use.
