# Commission Implementing Decision of 26 September 2014 establishing the best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the production of pulp, paper and board (notified under document C(2014) 6750) (Text with EEA relevance) (2014/687/EU), Division BAT 5: In order to reduce fresh water use and generation of waste water, BAT is to close the water system to the degree technically feasible in line with the pulp and paper grade manufactured by using a combination of the techniques given below.

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

Technique
Applicability
a
Monitoring and optimising water usage
Generally applicable
b
Evaluation of water recirculation options
c
Balancing the degree of closure of water circuits and potential drawbacks; adding additional equipment if necessary
d
Separation of less contaminated sealing water from pumps for vacuum generation and reuse
e
Separation of clean cooling water from contaminated process water and reuse
f
Reusing process water to substitute for fresh water (water recirculation and closing of water loops)
Applicable to new plants and major refurbishments.
Applicability may be limited due to water quality and/or product quality requirements or due to technical constraints (such as precipitation/incrustation in water system) or increase odour nuisance
g
In-line treatment of (parts of) process water to improve water quality to allow for recirculation or reuse
Generally applicable
The BAT-associated waste water flow at the point of discharge after waste water treatment as yearly averages are:
Sector
BAT-associated waste water flow
Bleached kraft
25 – 50 m3/ADt
Unbleached kraft
15 – 40 m3/ADt
Bleached sulphite paper grade pulp
25 – 50 m3/ADt
Magnefite pulp
45 – 70 m3/ADt
Dissolving pulp
40 – 60 m3/ADt
NSSC pulp
11 – 20 m3/ADt
Mechanical pulp
9 – 16 m3/t
CTMP and CMP
9 – 16 m3/ADt
RCF paper mills without deinking
1,5 – 10 m3/t (the higher end of the range is mainly associated with folding boxboard production)
RCF paper mills with deinking
8 – 15 m3/t
RCF-based tissue paper mills with deinking
10 – 25 m3/t
Non-integrated paper mills
3,5 – 20 m3/t
