<p>A continuous filtration process for solid dispersions, e.g. in production of dyestuffs, pharmaceuticals, uses the coarse fraction from the dispersion, which has been continuously separated in an earlier stage, as the auxiliary filtering layer, laid over a permeable support. Specifically, the fraction >5 mu m may be separated by centrifuging for this purpose. The advantage is that impurities are not removed with the filter cake.</p> |
