MDF separator can be a smaller size dedicated MDF separator, or a stand-by HFO separator
used for MDF.

Sludge tank (1T05)
The sludge tank should be located directly beneath the separators, or as close as possible
below the separators, unless it is integrated in the separator unit. The sludge pipe must be
continuously falling.
