Skimmer Manual
Revision 1 - December 2007
There is a shorter tube section at one end of the selective screen and a
longer section at the other end. When the shorter tube section is placed on
the bo om, the product is removed to a sheen. When the longer section is
down, the skimmer leaves a li le more oil in the well. This can enhance
oil movement into the well.
There are two screen sizes available (55 and 110 mesh). The 110 mesh is
standard and shipped with the SOS unless the 55 mesh is requested. The
55 mesh screen is used when more viscous oils (e.g. No. 2 fuel oil) must
be recovered.
The SOS will resist water intrusion up to several inches of water column.
If the SOS is submerged, the hydrostatic water pressure will overcome the
water repulsion ability of the screen and water will enter the skimmer. If
this happens, rinse the green screen in the recovered hydrocarbon to wash
off the water and reinstall the screen into the skimmer.
If the product contains a lot of very small suspended solids or biological
growth, the outer debris screen and perhaps the selective screen on the
skimmer may required periodic service or cleaning.
Caution:
Do not scrub the screen, this could destroy its selective properties.
