The industrial water used in Xinjiang's mining, photovoltaic, chemical, and power sectors largely comes from local groundwater and surface water, which differs significantly from the water quality in inland areas. It generally exhibits high mineralization, high salinity, excessive hardness, and significant water quality fluctuations. Ordinary industrial pure water equipment is ill-suited to Xinjiang's complex raw water conditions, easily leading to problems such as incomplete desalination, membrane fouling, substandard effluent quality, and frequent equipment malfunctions, directly impacting the stable operation of production lines and product yield. Therefore, many companies wonder: how to choose industrial deionized water equipment for Xinjiang's raw water?
Xinjiang's vast territory and significant differences in water quality between northern and southern Xinjiang are primary considerations for equipment selection. Northern Xinjiang's raw water is relatively mild, with moderate salinity and hardness, making conventional anti-fouling reverse osmosis equipment sufficient for basic industrial water needs. However, southern Xinjiang's groundwater is mostly brackish, with extremely high TDS, calcium and magnesium ion, and sulfate content, resulting in poor water quality. This places stringent requirements on the desalination capacity and anti-fouling performance of equipment, which ordinary single-stage reverse osmosis equipment simply cannot meet. Before selecting equipment, enterprises must test core indicators such as TDS, hardness, and turbidity of the raw water. They should abandon the generalized selection approach and adhere to the principle of "testing the water first, then matching the equipment," avoiding problems of poor equipment compatibility from the source.

For the high-salinity groundwater conditions in Xinjiang, the pretreatment system is the core of the equipment's long-term stable operation and is also the most easily overlooked key selection point. Xinjiang's raw water not only has high salinity but also contains a large amount of silt, colloids, and suspended solids, which can easily clog membrane elements and cause resin fouling and caking over long-term operation. When selecting equipment, an enhanced pretreatment system must be used, employing multi-media filters to intercept large particulate impurities, activated carbon filters to adsorb residual chlorine and organic matter, and precision filters to deeply filter out tiny impurities. If the raw water has high hardness and mineralization, fully automatic softening equipment and scale inhibitor dosing devices should be installed to effectively reduce water hardness, prevent reverse osmosis membrane scaling and clogging, and significantly extend the service life of core consumables.
The proper combination of core water purification processes is crucial to ensuring that the purified water produced from high-salinity groundwater meets standards. For basic production water and equipment cooling water, single-stage anti-fouling reverse osmosis equipment can be selected, suitable for the conventional water quality in northern Xinjiang, offering better cost-effectiveness. For high-salt brackish water and high-standard process water in southern Xinjiang, a double-stage reverse osmosis + EDI deep purification process is preferred. The double-stage reverse osmosis desalination rate can reach over 99%, effectively removing most salts, heavy metals, and impurities from the water, providing high-quality feed water for the downstream EDI system. EDI electro-deionization technology requires no acid or alkali regeneration, is environmentally friendly, and can stably produce high-purity deionized water, fully meeting the high-end water needs of new energy, fine chemicals, and power plant boiler feedwater.
To adapt to Xinjiang's special climate and operating conditions, the selection of equipment should also consider localized configuration. Xinjiang experiences large temperature differences between day and night and severe winters; therefore, the equipment must be equipped with pipe insulation and anti-freeze protection structures to prevent pipe freezing and cracking due to low temperatures, thus avoiding a decrease in equipment operating efficiency. Since many industrial and mining enterprises operate continuously for 24 hours, fully automatic intelligent control systems are preferred, supporting automatic flushing, intelligent start-up and shutdown, and real-time water quality monitoring, requiring no dedicated personnel and providing stable water production around the clock. Simultaneously, the equipment tonnage is matched according to water consumption, with sufficient operational margin reserved to avoid insufficient water quality and quantity during peak water usage periods.
