Separating substances

Separating substances

1. Filtration

   • Filtration is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass, but not the solid. The term "filtration" applies whether the filter is mechanical, biological, or physical. The fluid that passes through the filter is called the filtrate

2. Evaporation

3. Crystallization

4. Filitration

   • Is a process used to separate solids from liquids or gases using a filter medium that allows the fluid to pass, but not the solid. The term "filtration" applies whether the filter is mechanical, biological, or physical. The fluid that passes through the filter is called the filtrate

5. Evaporation

   • Is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance.

6. Crystallization

   • is also a chemical solid–liquid separation technique, in which mass transfer of a solute from the liquid solution to a pure solid crystalline phase occurs. In chemical engineering, crystallization occurs in a crystallizer.
