| 摘要 |
The present invention concerns a cross-flow filtration apparatus (10) comprising a filtration means (50) having a feed inlet means (18,22), a permeate outlet means (16) and a retentate outlet means (20). The feed inlet means of the apparatus (10) includes a first conduit (18) in fluid communication from a process zone (12) to a buffer zone (14) and a second conduit (22) in fluid communication from the buffer zone (14) to the filtration means (50). The retentate outlet means (20) is in fluid communication with the buffer zone (14) and the permeate outlet means (16) is in fluid communication with the process zone (12). In use, substantially undiluted permeate is accumulated in the process zone (12), whilst a suspension of retained matter is accumulated in the buffer zone (14). The apparatus (10) of the present invention is suitable for treating wash liquor from laundry or dishwashing machines or the like. <IMAGE> |
