Division 37

United Kingdom

BAT is to reduce emissions from downstream processes by using one or a combination of the following techniques:

Technique^f1	Applicability
A description of the techniques is given in Sections 1.10.7 and 1.10.8.
(i) Wet scrubbing systems	The techniques are generally applicable for the treatment of waste gases from the forming process (application of the coating to the fibres) or secondary processes which involve the use of binder that must be cured or dried
(ii) Wet electrostatic precipitator
(iii) Filtration system (bag filter)	The technique is generally applicable for the treatment of waste gases from cutting and milling operations of the products
