Ultrapure water treatment equipment

Working Principle of Laboratory Ultrapure Water Machine
The working principle of the 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 device. The purified water is stored in a storage tank, achieving regional Grade 3 water standards, while the wastewater produced by the reverse osmosis device is discharged. Reverse osmosis purified water undergoes further deep desalination through purification columns to produce Grade 1 or ultrapure water. If there are special requirements, ultraviolet sterilization or microfiltration, ultrafiltration, and other devices are added after the ultrapure water stage to remove residual bacteria, particles, pyrogens, etc. Precision filter cartridges, activated carbon filter cartridges, reverse osmosis membranes, and purification columns are materials with relatively limited lifespans. The precision filter cartridges and activated carbon filter cartridges actually serve to protect the reverse osmosis membrane.

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