Equipment Summary


As the rapid development of technology, the quality level of LCD is higher and higher.
During manufacturing, the washing process is an important step, and the water source must be of very high quality.  Therefore, ultra-pure water system is essential. We adopted 2-stage RO system with EDI module and polishing mixed bed to reach the desalination rate of more than 98%.  

Processing Technology



Characteristics
1. Modular design, fully automatic control.

2. Raw water tank, 1-stage and 2-stage pure water tank, RO membrane and EDI module can be automatically washed.

3. Different modules will automatically switch to self-circulation mode, which guarantees no dead water exists.

4. Low pressure switch is equipped to protect the high pressure pump form damage in case of water cut.

5. Water quality monitoring system continuously showing out the output water quality to prevent production loss from unqualified water.

6. Pressure monitoring system is equipped to RO membrane to figure out the washing time for RO membrane.

7. Water tank is equipped with liquid level controller.

8. Top brand pump, gauge and RO membrane is adopted.

9. Sanitary tubes are automatic welded and endoscope tested to guarantee evenly welding without dead angle. So that the tube system could be easily clean and hard for bacteria breed. Then output water quality is guaranteed.
