Traduction de «Effluent d'épuration » (Français → Anglais) :

16. BAT is to reduce dust emissions from the waste gases of the melting furnace by applying a flue-gas cleaning system such as an electrostatic precipitator or a bag filter.

All processes directly or indirectly linked to the production of phenol and acetone are included, in particular air compression, hydroperoxidation, cumene recovery from spent air, concentration and cleavage, production fractionation and purification, tar cracking, acetophenone recovery and purification, AMS recovery for export, AMS hydrogenation for ISB recycle, initial waste water purification (first waste water stripper), cooling water generation (e.g. cooling towers), cooling water utilisation (circulation pumps), flare and incinerators (even if physically located OSB) as well as any support fuel consumption

How are emission limit values for discharges of waste water from flue gas cleaning equipment to the aquatic environment determined?

- the fact that their uncontrolled use can have harmful effects on human health and the environment, e.g. the uncontrolled spreading of sewage sludge on agricultural land and the uncontrolled application of livestock manure on agricultural land, particularly in nitrates vulnerable zones.

The objectives in this field, which are contained in the "Plan Nacional de Saneamiento y Depuración de Aguas Residuales Urbanas" (National Sewerage and Wastewater Treatment Plan), are the improvement of the sewerage and of the waste-water treatment systems, a greater control of the quality of discharges with a view to reuse of treated effluents and improved management and disposal of waste-water sludges.

A large number of projects concerned with the treatment of waste water and effluent, mainly from urban areas, have been part-financed in a number of large and medium-sized regional towns.
