Liquid-solid particle separation process |
摘要 |
A liquid-solid particle sepation process is disclosed, which is characterized by comprising the repetition of feeding waste solution containing fine solid particles to a membrane-type separator and feeding at least part of the solution concentrated with particles therefrom back to the membrane-type separator on one hand while providing the concentrated solution to a centrifugal separator on the other. The process exhibits that the permeability of the membrane can be kept almost as good as in the beginning of filtering operation.
