paper bａnd filter is used to filter the coolant in metal grinding or other processing, also suitable for the cleaning fluid in the cleaning system of hair and blank parts, the removal of impurities in industrial water, organic solution and other solutions.
paper bａnd filter for solid-liquid separation and separation of solid and liquid phases from a suspension
.it is used in many production processes with the purpose of:
1) recovery of liquid phase;
2) recovery of valuable solid phase;
3) simultaneous recovery of solid and liquid phases.
the liquid phase is typically entrapped with a number of fine solid particles, and the solid phase contains a number of liquid, the latter is a more common problem.the imperfections of this separation can be represented in two ways:
1) separation efficiency, which represents the mass recovery rate of solid phase (also known as rejection rate in filtration operation), usually expressed as a percentage;
2) wet content (mass fraction), denotes the dry and wet degree of the recovered solid phase.it is also regarded as reducing or recovering the liquid accumulated in the solid phase. it is also necessary to wash the solid phase and replace the mother liquor with washing.
in addition to solid and liquid separation, paper bａnd filters often require the removal of too coarse or too fine particles (such as desanding or desliming) from the product, a process called grading.
before the separation of solid and liquid, it can also be classified in advance, so that the material with different particle size range can be handled by more suitable equipment.
it can be achieved on many solid and liquid separation equipment, paper bａnd filter because the separation principle used in these equipment is closely related to particles are too small
