What are the production equipment of ultra-pure water?

The core equipment for making ultra-pure water mainly includes the following:
1. Reverse Osmosis System (RO)
Reverse osmosis is one of the most commonly used techniques for preparing ultrapure water. It removes most ions, particles and organic matter from water. Higher purity can be achieved by multi-stage reverse osmosis.
2. Ion exchange column
The ion exchange column uses resin exchange to adsorb the ionic impurities in the water to further improve the purity of the water. Different levels of ion exchange can achieve different degrees of ion removal.
3. Ultrafiltration/microfiltration membrane
Ultrafiltration and microfiltration membranes can remove macromolecular organic matter, colloids and bacteria and other particulate impurities. Compared with reverse osmosis, they have a weaker removal effect on dissolved ions.
4. Electrical Deionization System (EDI)
Electrodeionization combines ion exchange and electrodialysis technology to sustainably remove ionic impurities from water and achieve higher purity. This method is simple to operate and easy to automate control.
5. Ultraviolet sterilization system
Ultraviolet radiation can effectively kill microbial pollution such as bacteria and viruses in water. It is often used in combination with other technologies to ensure the high cleanliness of ultra-pure water.
6. Online monitoring system
Equipped with electrical conductivity, pH, dissolved oxygen and other online monitoring instruments, real-time monitoring of water quality parameters, timely detection of anomalies and feedback adjustment.
These core equipment are usually integrated in a complete ultra-pure water preparation system, supplemented by a variety of pre-treatment, post-treatment and other supporting facilities to ensure the continuous stability of ultra-pure water quality. Advanced manufacturing processes are also continuously optimizing the performance of these units to meet the increasingly demanding ultra-pure water requirements.
