The reverse osmosis unit of the ultrapure water machine is very important in the entire water treatment system. The reverse osmosis water not only determines the quality of the pure water used by the user, but also affects the treatment effect of the subsequent purification unit, indirectly affecting the ultrapure water quality.
If you want to ensure that the water quality of pure water is stable and up to standard, a good way is to use two-stage reverse osmosis instead of the one-stage reverse osmosis that is common in the market today. The advantages of two-stage reverse osmosis are:
1. Ensure that the produced RO water is not affected by the raw water quality
Since the influent water is tap water, and the water quality of tap water cannot be guaranteed, and the desalination capacity of reverse osmosis is limited, the pure water produced will change with the change of influent water quality, that is to say, when the influent water quality is poor Pure water is also not up to standard.
Aikepu's deep desalination technology can fully filter the influent water to ensure that the output pure water is stable and meets the water quality standards, regardless of the quality of the influent water, it can ensure that the produced water is less than 5μs.
2. Improve the utilization rate of raw water
The traditional one-stage reverse osmosis only treats the raw water once, leaving pure water to drain the concentrated water, which will cause more waste; the two-stage reverse osmosis adopts a unique circulation technology to allow the raw water to be treated repeatedly , can artificially adjust the discharge of concentrated water to ensure that the utilization rate of raw water is above 60%, saving resources and cost.
3. Guarantee the service life of the purification column
If the quality of pure water produced by the reverse osmosis unit does not meet the specifications, then the loss of the purification column will be great, and the purification column is relatively expensive, so high-quality pure water will also prolong the service life of the purification column, which will greatly cost savings.
From this point of view, the application of two-stage reverse osmosis in ultrapure water machines is an inevitable trend and will become more popular in the future.
