8. Additional Installation Piping for Separator Accessiblity: Separators which
feature a removable upper chamber should be installed with a spool in order to
facilitate the removal of the upper chamber.
9. Flanges/Couplings: All flanges and/or grooved couplings should have the
appropriate gasket/seal in order to ensure a leak-free installation. All hand hole
clean-out ports and other internal access devices should also be properly re-sealed
after use.
10. Air Relief Ports: The appropriate air relief ports should be used at start-up to expel
air from the separator.
If the separator will be drained periodically or exposed to entrained air or gases from
the piping system, air vents should be permanently installed.
11. Down Stream Filtration: The use of finer filtration (polishing) downstream from
the separator is a common application. Be aware, however, that the barrier filter (as it
accumulates more solids) causes an increasing pressure loss, which may cause the
flow rate of the system to be reduced…sometimes below the recommended flow rate
of the separator. This situation will often reveal itself when typical separable solids
begin to show up regularly on the downstream barrier filter (leading the customer to
possibly believe that the separator does not work). Always check for variations in the
flow rate when down stream conditions change.
