# 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 iron and steel production (notified under document C(2012) 903) (Text with EEA relevance) (2012/135/EU), Division 92

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

BAT is to minimise the waste water discharge from continuous casting by using the following techniques in combination:
I.. the removal of solids by flocculation, sedimentation and/or filtration
II.. the removal of oil in skimming tanks or in any other effective device
III.. the recirculation of cooling water and water from vacuum generation as much as possible.
The BAT-associated emission levels, for waste water from continuous casting machines, based on a qualified random sample or a 24-hour composite sample, are:
— suspended solids < 20 mg/l
— iron < 5 mg/l
— zinc < 2 mg/l
— nickel < 0,5 mg/l
— total chromium < 0,5 mg/l
— total hydrocarbons < 5 mg/l
