The salt content in the recycled water from a factory is very high; can it be used as water for pulp production? Why?
Generally, no. The balance of salts in water is taken into consideration; excessive salt levels used in coal slurry preparation will inevitably accumulate within the system, leading to severe scaling in the pipes of the black water and gray water systems, with significant negative consequences.
Agree with the person above. Additionally, high salt levels affect the pulp-forming properties as well as the concentration of the pulp; the impact on pipeline corrosion also needs to be taken into account.
If the salt contains chlorine, the corrosion resistance of the relevant stainless steel equipment is significantly reduced.
The answer from upstairs – I’ve learned it……………………
What paste to make? It wasn’t explained clearly. Making coal slurry is definitely not good.
Desalination is a challenging part of chemical processes; it’s a really troublesome task. :(
As the person upstairs said, it’s really difficult to deal with. . . I also have a question: once the COD level reaches around 80, how can it be further reduced to around 30? It should still contain fluorine compounds as well as organic substances. There are also chloride ions, and salts. . .
