A solid-liquid separation process |
摘要 |
A process for separating solids from liquids in a filtration zone defined by a higher concentration zone and a lower concentration zone separated by a filter. The process includes the steps of directing a slurry feed comprising a liquid and solids into the higher concentration zone directing a displacement fluid to the higher concentration zone countercurrent to the flow of the slurry feed and passing at least a portion of the liquid through a filter to the filtrate zone, producing a filtrate.
