By which process can we get soap from soap water?

In: Science, Chemistry, Soaps and Detergents [Edit categories]

Answer:

One approach would be some kind of membrane process like ultra- or nanofiltration.

The questions to answer first are:
* How much water do you want to process?
* Do you want the soap or the water?
* What costs are acceptable?

Membrane processes are physical pocesses, and they require substantial pressure to work.
