Optoelectronic/Electronic Ultra Pure Water Equipment

1、 Equipment Introduction
Production, processing, and cleaning of optoelectronic materials;LCDLCD display screenPDPPlasma display screen, high-quality fluorescent tube cathode ray tube, microelectronics industryFPC/PCBCircuit boards, circuit boards, large-scale and ultra large scale integrated circuits require a large amount of high-purity water and ultrapure water to clean semi-finished and finished products. The higher the integration level of integrated circuits, the higher the requirements for water quality, which also puts forward stricter requirements for the simplicity, automation level, production continuity, sustainability, and other aspects of ultrapure water treatment processes and products. grow luxuriantlyThe foundation of environmental protection in meeting user water standardsOn the basis of this, the water tanks in the equipment system are equipped with liquid level control systems, the water pumps are equipped with pressure protection devices, online water quality detection and control instruments, and electrical systems are usedPLCProgrammable controllers truly achieve unmanned operation, while adopting a unified method of recommendation and customer requirements in process material selection, making the equipment more cost-effective and reliable compared to other similar products.

4、 Design Features

1. The system adopts fully automatic control(Manual control can also be used, and automatic backwashing and regeneration programs can be set during system operation;

2. All unit wiring is completed uniformly in the factory, reducing installation and debugging time;

3. The first and second stage reverse osmosis systems are equipped with reflux pipelines, and the reverse osmosis equipment is equipped with chemical cleaning devices;

4. Pipelines are generally usedUPVCtexture of material;

5. Integrated control system and integrated instrument system, etc., facilitate operation and management;

6. ROfilmRegular cleaning Equipped with startup and scheduled cleaningROMembrane function, extendedROMembrane service life;

7. Water recovery rate Through special process design, the equipment's performance has been significantly improvedrate of recovery, up to a maximum of70%；

8. The equipment has an automatic prompt function for consumables replacement, and the replacement cycle of consumables depends on changes in water quality and pressure, rather than the usage time of consumables. Considering the differences in water quality in different regions, the design is more scientific;

9. self-protection The automatic shutdown protection function for source water shortage also has the functions of automatic water production for water tank shortage and automatic shutdown for full water.
