PCT No. PCT/NO90/00075 Sec. 371 Date Dec. 23, 1992 Sec. 102(e) Date Dec. 23, 1992 PCT Filed Apr. 27, 1990 PCT Pub. No. WO91/16981 PCT Pub. Date Nov. 14, 1991.A method and apparatus for removing sedimented particles from a fluid stream in a settlement basin. In the bottom of the basis there is a sluice which may include a sluice gate. The basin includes a longitudinal, flexible pipe unit which is shaped such that it can seal the edges of the sluice. The pipe unit can move up and down within the basin by filling the pipe with a fluid, i.e. water or air. Depending on the initial position of the pipe, upward or downward movement causes the pipe to seal against the edges of the sluice. By adjusting the amount of water and air in the pipe, it is possible to adjust the extent to which the sluice is sealed. |
