Once salt water

When using Kai membranes to treat brine, the water that enters the water distribution tank is treated brine, which comes from the filtrate pump. Is there any other component in the composition of this treated brine besides water and NaCl? If there are other components, what is their content? How much is there in the filtrate approximately? What are the components of the brine after treatment with Kay membrane, and what are their respective concentrations? Thank you! ! # ， ， &
Why is no one paying attention to me? Thank you all first
Please explain the specific processes; the terms for filtrate and water distribution tanks are somewhat unfamiliar to me
It seems that those on the third floor have never been exposed to the brine process at all; there is only one water distribution tank, namely the one used before the evolution salt pond was created
The levels of other impurities in the water in the water distribution tank should be very low, as the dechlorinated salt water comes from the electrolysis cells and contains few impurities； The filtrate comes from salt sludge; the brine in this sludge contains soda ash and caustic soda at the levels required for control. If no impurities are introduced from the salt sludge, its impurity content remains low as well ； The impurities in the resin column wash liquid are also low. If you really want to know its condition, you might as well use ICP analysis.
The salt composition in the water distribution tank is not constant, as the filtrate is added intermittently, and water from other sources within the system also causes changes in the components of this tank. The approximate values are as follows: salt content, around 150 g/l； pH, around 10 ； Free chlorine varies depending on the manufacturing processes of different manufacturers; at present, it is at 5-10 ppm ； The temperature varies depending on the manufacturing processes of different manufacturers; at present, it is between 50 and 55 degrees. The sulfate concentration should be in the range of 3-4; otherwise, the sulfate level in the brine will exceed the allowed limit ； The other heavy metal ion indicators are meaningless.

What is the flow rate of the alkaline solution used per unit volume of brine? We use brine made from well water, and we produce 50,000 tons of ion-exchange membrane caustic soda per year, with a concentration of 0.4 grams per liter of alkali
