　　（2） Technical requirements for specialized ultrapure water machines for the biological industry

1. High end water quality: resistivity 18.2M Ω NaN (25 ℃), bacteria<1CFU/ml; TOC<5ppb。

2. Dual stage reverse osmosis process, equipped with small output dual pump dual stage reverse osmosis technology.

3. The system produces 20L/H of water and is equipped with a 40L closed pressure water storage tank, which has a low probability of secondary pollution and a long maintenance cycle.

4. Online LCD conductivity+resistivity 2-stage monitoring, the conductivity meter used in the equipment needs to be calibrated with a foreign first-line brand conductivity meter. .

5. Online self diagnosis of abnormal system operation (water quality and quantity of raw water, pre purified water, and ultrapure water), warning or automatic system shutdown.

6. Intelligent fault diagnosis (online replacement indication for important system components such as solenoid valves, booster pumps, UV lamps, sensors, etc.).

　　（3） Maintenance of specialized ultrapure water machines for the biological industry

Firstly, let's have a brief introduction to the laboratory ultrapure water machine. The tap water is pre treated with precision filters and activated carbon filters to filter out particles such as sediment and absorb odors, making the tap water cleaner. Then, it is purified and desalinated through a reverse osmosis device. The purified water is stored in a water storage tank and can meet the national third level water standard. At the same time, the wastewater (also known as "concentrated water") produced by the reverse osmosis device is discharged. Reverse osmosis pure water is subjected to deep desalination treatment through a purification column to obtain primary water or ultrapure water. Finally, if the user has special requirements, ultraviolet sterilization or microfiltration, ultrafiltration and other devices are added after the ultrapure water to remove residual bacteria, particles, heat sources, etc. in the water.

Precision filter cartridges, activated carbon filter cartridges, reverse osmosis membranes, and purification columns are all materials with relative lifetimes. Precision filter cartridges and activated carbon filter cartridges actually protect the reverse osmosis membrane. If they fail, the load on the reverse osmosis membrane will increase and the lifespan will be shortened. If the machine continues to operate, the quality of the pure water produced will decrease, which will increase the burden on the purification column and shorten its lifespan. The ultimate result is an increase in the cost of using ultrapure water machines.
