Working Principle of Laboratory Ultrapure Water Machine
The working principle of a laboratory ultrapure water machine involves pretreatment of tap water through precision filter cartridges and activated carbon filter cartridges to remove particles such as sediment and adsorb odors, making the tap water cleaner. The water then undergoes purification and desalination via a reverse osmosis (RO) device. The purified water is stored in a storage tank, meeting the regional Grade 3 water standard, while the wastewater produced by the RO device is discharged. The RO purified water undergoes further deep desalination through a purification column to obtain Grade 1 or ultrapure water. If there are special requirements, additional devices such as UV sterilization, microfiltration, or ultrafiltration are added after the ultrapure water stage to remove residual bacteria, particles, pyrogens, etc. The precision filter cartridge, activated carbon filter cartridge, RO membrane, and purification column are all materials with a limited lifespan. The precision filter cartridge and activated carbon filter cartridge actually serve to protect the RO membrane.

Note: 1. Inlet water quality affects output water quality and the lifespan of filter columns; 2. When source water quality is poor (TDS >200ppm), RO water quality may drop to above 10μs/cm2; 3. For raw water with TDS >500, a water softener is recommended.
