Abstract
A method for packing a media bed in a column (3) from a slurry being a dispersion of said media particles and a liquid, said method comprising the steps of: a) estimating a slurry concentration; b) filling the column (3) with a certain volume of the slurry from a slurry tank (13) connected to the column; c) packing a test media bed from the slurry; d) detecting where the test media bed is consolidated; e) use the information about the consolidated test media bed height for providing to the column an amount of slurry that after further packing will give a user target bed height; f) packing a media bed from the slurry.
Claims3
A method for packing a media bed in a column (3) from a slurry being a dispersion of said media particles and a liquid, said method comprising the steps of:
- a) estimating a slurry concentration;
- b) filling the column (3) with a certain volume of the slurry from a slurry tank (13) connected to the column;
- c) packing a test media bed from the slurry;
- d) detecting where the test media bed is consolidated;
- e) calculating a slurry concentration of slurry remaining in the slurry tank by using information from the consolidated test bed height and introducing more slurry of this known slurry concentration while the test bed is kept in the column, the amount of introduced slurry being controlled such that a user target bed height will be achieved after further packing;
- and
- f) packing a media bed from the slurry.
