ABSTRACT:
A process for filtering a liquid through a combination of a first sieve, a sand pack and a second sieve in the direction of flow of the liquid, is described. This process differs from the known process in that the liquid passes through a filter pack in which the mesh width of the first sieve is at most equal to the mesh width of the second sieve, and the mesh width of the second sieve is smaller than the smallest particle size of the sand in the sand pack. Furthermore, the mesh width of the second sieve is at most 80 microns.
When using this process uniform filaments without variations in titer from filament to filament or over the length of a filament are obtained. The rise in pressure relating to time is very small.
