Abstract
The present invention is a filtration method and device for separating particles of a suspension according to their mass. The invention includes a rotating uncloggable filter. The filter rotates inside of a stationery housing. Separation by particle size is achieved by adjusting the rotational speed of the filter. The filter is particularly useful for washing photographic suspensions.
