# Commission Implementing Decision of 28 February 2012 establishing the best available techniques (BAT) conclusions under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions for the manufacture of glass (notified under document C(2012) 865) (Text with EEA relevance) (2012/134/EU), Division 13

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

BAT is to reduce the emission load of pollutants in the waste water discharges by using one or a combination of the following waste water treatment systems:
Technique
Applicability
(i)
Standard pollution control techniques, such as settlement, screening, skimming, neutralisation, filtration, aeration, precipitation, coagulation and flocculation, etc.
Standard good practice techniques to control emissions from storage of liquid raw materials and intermediates, such as containments, inspection/testing of tanks, overfill protection, etc.
The techniques are generally applicable
(ii)
Biological treatment systems, such as activated sludge, biofiltration to remove/degrade the organic compounds
The applicability is limited to the sectors which use organic substances in the production process (e.g. continuous filament glass fibre and mineral wool sectors)
(iii)
Discharge to municipal waste water treatment
Plants
Applicable to installations where further reduction of pollutants is necessary
(iv)
External reuse of waste waters
The applicability is generally limited to the frits sector (possible reuse in the ceramic industry)
Table 5
BAT-AELs for waste water discharges to surface waters from the manufacture of glass
The relevance of the pollutants listed in the table depends on the sector of the glass industry and on the different activities carried out at the plant.
The levels refer to a composite sample taken over a time period of 2 hours or 24 hours.
For the continuous filament glass fibre sector, BAT-AEL is < 200 mg/l.
The level refers to treated water coming from activities involving acid polishing.
In general, total hydrocarbons are composed of mineral oils.
The higher level of the range is associated with downstream processes for the production of lead crystal glass.
