Ultra-pure water machine with pretreatment, reverse osmosis technology, ultra-purification treatment and post-treatment
In other ways, the conductive medium in the water is almost completely removed, and the colloidal substances, gases and organic substances which are not dissociated in the water are removed to a very low level of water treatment equipment.

First of all, simply understand the laboratory ultra-pure water machine, the tap water is pre-treated through the precision filter element and the activated carbon filter element, filtering the sediment and other particulate matter and adsorbing the odor, so that the tap water becomes cleaner, and then the water is purified and desalted by the reverse osmosis device. The purified water is stored in the storage tank, and the water quality can reach the national three-level water standard, and the wastewater produced by the reverse osmosis device (also called "concentrated water") is discharged. The reverse osmosis pure water is subjected to deep desalting treatment through the purification column to obtain first-grade water or ultra-pure water. Finally, if the user has special requirements, ultraviolet sterilizing or microfiltration, ultrafiltration and the like are added after the ultrapure water to remove residual water. Bacteria, particles, heat sources, etc.
Precision filter element, activated carbon filter element, reverse osmosis membrane and purification column are all materials with relative life. The precision filter element and activated carbon filter element are actually the protection of reverse osmosis membrane. If they fail, the load of reverse osmosis membrane will be aggravated and the service life will be reduced. If the water is turned on, the quality of the pure water produced will decrease, which will increase the burden on the purification column, and the life of the purification column will be shortened. The end result is an increase in the cost of using ultrapure water machines. Therefore, in the use of laboratory ultra-pure water machines, there are the following aspects that need attention.
Process configuration
1. Pretreatment system → reverse osmosis system → intermediate water tank → coarse mixed bed → fine mixed bed → pure water tank → pure Water Pump → ultraviolet sterilizer → polishing mixed bed → precision filter → water object (≥18MΩ.CM) (traditional Process)
2. Pretreatment→Reverse Osmosis→Intermediate Water Tank→Water Pump→EDI Device→Purification Water Tank→Pure Water Pump→UV Sterilizer→Polishing Mixed Bed→0.2 or 0.5μm Precision Filter→Water Object (≥18MΩ.CM) (Latest Process)
3. Pretreatment → first-stage reverse osmosis → dosing machine (pH adjustment) → intermediate water tank → second-stage reverse osmosis (positive charge reverse osmosis membrane) → pure water tank → pure water pump → EDI device → ultraviolet sterilizer → 0.2 or 0.5μm precision filter → water object (≥17MΩ.CM) (latest process)
4. Pretreatment→Reverse Osmosis→Intermediate Water Tank→Water Pump→EDI Device→Pure Water Tank→Pure Water Pump→UV Sterilizer→0.2 or 0.5μm Precision Filter→Water Object (≥15MΩ.CM) (Latest Process)
5. Pretreatment system → reverse osmosis system → intermediate water tank → pure water pump → coarse mixed bed → fine mixed bed → ultraviolet sterilizer → precision filter → water object (≥15MΩ.CM) (traditional process)
