The filter material is preconcentrated
(2) centrifugal sedimentation method: the use of hydrocyclone to achieve.
(T) Gravity sedimentation method: commonly used equipment rake type enrichment book l, deep cone thickener, and concentrated funnel.
One of the ways to solve the difficult to filter is to pre-concentrate, pre-concentrated method there are three:
Increase, in a very short period of time was forced to stop the filter, the media rinse regeneration.
The fine particles entrained in the solid phase of the suspension are the main reason for the difficulty in filtration during the filtration process. The fine particles enter the medium and deposit on the surface of the medium to form the slurry layer, so that the filtrate channel is extremely narrow and the filtration resistance is very fast
