One, easy to scale
Because it is concentrated four times times the concentration of water, so this water in the silica content, alkalinity is large, and many scaling salts such as: CaCO3, CaSO4, BaSO4, SrSO4 and so on, their ionic product is far greater than its concentration, if not effective methods to control, scaling is inevitable.

Second, easy to get dirty plugging
In reverse osmosis concentrated water, trace amounts of organic matter and colloids in the water are enriched, and if there is no effective control, it will also cause dirt plugging of the reverse osmosis membrane.
Third, easy to pollute In reverse osmosis concentrated water, the microorganisms in the water are accelerated to grow under the action of various enriched nutrients, which will cause biological pollution of the reverse osmosis membrane, so it should also be effectively controlled.
