TEST FOR SEPARATION CAPABILITY
In order to test the separation capability of the medium supplied to the separator, you can perform a
simple suitability test. Take some of the medium intended for separation into your hand and try to
press it out. If the medium is a very fine-grained solid and seeps through your fingers during this test, it
cannot be mechanically separated without reducing the viscosity.
However, if liquid escapes through your fingers and solid matter remains in your hand when opened,
then this medium can be separated in the separator.
You can also perform this test with the effluent of the separator to determine whether further separa-
tion in the separator is possible by using screens with lower gap widths. For example, if the first sepa-
rator is operated with a gap width of 0.75 mm, the effluent can be introduced to a separator with a gap
width of 0.25 mm and so on.
To determine the possible dry matter content for your application using the separator, perform a
screen test, such as with a screen of gap width 0.50 mm. The dry matter content when using the sepa-
rator will always be higher than your test result since the solids are filtered by the solid cake, meaning
that even solids with a size smaller than 0.50 mm will be captured in the cake.
If the demand for the separated medium is very high, such as when expanding operations, it is possi-
ble as well as effective to run multiple separators in parallel as shown in Fig. 9-1.
It should be noted here that, in this case, an elevated tank should be used in order to evenly supply the
separators in parallel. Also ensure that the liquid pressure on the separator does not exceed a value of
2 m water column.
