# 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 49: In order to reduce emission loads of coating colours and binders which can disturb the biological waste water treatment plant, BAT is to use technique (a) given below or, in case this is technically not feasible, technique (b) given below.

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

Technique
Description
Applicability
a
Recovery of coating colours/recycling of pigments
Effluents containing coating colours are collected separately. The coating chemicals are recovered by e.g.:
(i) ultrafiltration;
(ii) screening-flocculation-dewatering process with return of the pigments to the coating process. The clarified water could be reused in the process
For ultrafiltration, the applicability may be restricted when:
effluent volumes are very small
coating effluents are generated in various places of the mill
many changes in coating occur; or
different coating colour recipes are incompatible
b
Pretreatment of effluents which contain coating colours
Effluents which contain coating colours are treated e.g. by flocculation to protect the subsequent biological waste water treatment
Generally applicable
