Countercurrent decantation |
| abstract |
In countercurrent decantation, upwardly flowing liquid is treated with downwardly falling solids in a progressive series of vertically stacked treatment cells. Solids fall through a valve from one cell to the next. The valve is a buoyant sphere which will sink, to open, under a weight of solids, but the valve is sufficiently buoyant to close when there is still enough solid queuing thereon to prevent liquid from passing through it. |
