Abstract
The present invention provides a method and apparatus for separating a mixture to be separated (solid-liquid or liquid-liquid mixture) using a deliquescent filter medium. The mixture to be separated is separated into a liquid passing through a filter layer of the filter medium and a captured material captured in the filter layer.

A method using a deliquescent filter medium for separating a mixture to be separated, the method comprising:
- a) a step of forming mother liquid crystals from a mother liquid;
- b) a step of forming deliquored filter crystals by deliquoring the mother liquid crystals;
- c) a step of forming a crystal-filter layer of the deliquored filter crystals and supplying a mixture to be separated to a surface of the formed crystal-filter layer to separate the mixture to be separated into a passing liquid passing through the crystal-filter layer and a crystal-filter layer supporting wall having holes, and a captured material captured in the crystal-filter layer, the average distance between the holes of the crystal-filter layer supporting wall having holes being longer than the average thickness of the crystal-filter layer to which the mixture to be separated is being supplied;
- d) a step of melting the crystal-filter layer among the crystal-filter layer and the captured material captured in the crystal-filter layer;
- and
- e) a step of separating, by gravity settling, the melted crystal-filter layer and the captured material captured in the crystal-filter layer.

- and
- d) a tank in which the melted crystal-filter layer and the material captured in the crystal-filter layer are separated by gravity settling separation.
