Extent: E+W+S+N.I.

Technique
Applicability
a
Dry debarking (description see Section 1.7.2.1)
Restricted applicability when high purity and brightness is required with TCF bleaching
b
Handling of wood logs in such a way as to avoid the contamination of bark and wood with sand and stones
Generally applicable
c
Paving of the wood yard area and particularly the surfaces used for the storage of chips
Applicability may be restricted due to the size of the wood yard and storage area
d
Controlling the flow of sprinkling water and minimising surface run-off water from the wood yard
Generally applicable
e
Collecting of contaminated run-off water from the wood yard and separating out suspended solids effluent before biological treatment
Applicability may be restricted by the degree of contamination of run-off water (low concentration) and/or the size of the waste water treatment plant (large volumes)
The BAT-associated effluent flow from dry debarking is 0,5 – 2,5 m3/ADt.
