Seek advice on methods for removing water from organic substances

Given the large amount of water involved, distillation isn’t a viable option. I would like to ask everyone what specific methods can be used to remove water from organic materials. hcbbs !! hcbbs
Haichuan is very enthusiastic, so why is there no activity? .
It’s your question that isn’t clear. When water is mixed with organic substances, the following situations can occur: 1. It is miscible with water and forms an azeotropic system: very difficult to separate. 2. It is miscible with water but no azeotropic system is formed: very difficult to separate. 3. It is soluble in water, but the boiling points of the components are close to each other: also difficult to separate. 4. It is soluble in water, but the boiling points of the components differ significantly: easier to separate. 5. It is insoluble in water: easier to separate. 6. The situation becomes more complex when there are multiple components. The separation method is determined by considering the physical properties of the components, the amount of material, and the process conditions, as well as various other factors, in order to select a suitable separation approach. You don’t even tell everyone what organic substance you need to separate (maybe you don’t even know it), so who can explain it to you? I just found you unfamiliar, so out of sympathy I gave you some advice.
Senior from Kaichuan University, what you said makes sense, but aren’t your words a bit too harsh? The organic compounds we produce are soluble in 10 times their volume of water. To control the direction of the reaction, some of the water needs to be removed first; using static separation isn’t feasible. I won’t go into too much detail as to why, but distillation is too energy-intensive. My question is: are there any other separation methods available? It’s about quickly carrying out a rough separation of that kind, something that is feasible, haha. Thank you.
Everything you’ve suggested involves distillation separation; we’ve already considered that, haha
It’s not a small amount; it’s around 20–30%.
I’m asking about the amount of material you have to handle each day, not the water content.
