  "text": "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:\nTechnique\nApplicability\n(i)\nStandard pollution control techniques, such as settlement, screening, skimming, neutralisation, filtration, aeration, precipitation, coagulation and flocculation, etc.\nStandard good practice techniques to control emissions from storage of liquid raw materials and intermediates, such as containments, inspection/testing of tanks, overfill protection, etc.\nThe techniques are generally applicable\n(ii)\nBiological treatment systems, such as activated sludge, biofiltration to remove/degrade the organic compounds\nThe applicability is limited to the sectors which use organic substances in the production process (e.g. continuous filament glass fibre and mineral wool sectors)\n(iii)\nDischarge to municipal waste water treatment\nPlants\nApplicable to installations where further reduction of pollutants is necessary\n(iv)\nExternal reuse of waste waters\nThe applicability is generally limited to the frits sector (possible reuse in the ceramic industry)\nTable 5\nBAT-AELs for waste water discharges to surface waters from the manufacture of glass\nThe 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.\nThe levels refer to a composite sample taken over a time period of 2 hours or 24 hours.\nFor the continuous filament glass fibre sector, BAT-AEL is < 200 mg/l.\nThe level refers to treated water coming from activities involving acid polishing.\nIn general, total hydrocarbons are composed of mineral oils.\nThe higher level of the range is associated with downstream processes for the production of lead crystal glass.\nParameter\nUnit\nBAT-AEL(composite sample)\npH\n—\n6,5 – 9\nTotal suspended solids\nmg/l\n< 30\nChemical oxygen demand (COD)\nmg/l\n< 5 – 130\nSulphates, expressed as SO4 2–\nmg/l\n< 1 000\nFluorides, expressed as F–\nmg/l\n< 6\nTotal hydrocarbons\nmg/l\n< 15\nLead, expressed as Pb\nmg/l\n< 0,05 – 0,3\nAntimony, expressed as Sb\nmg/l\n< 0,5\nArsenic, expressed as As\nmg/l\n< 0,3\nBarium, expressed as Ba\nmg/l\n< 3,0\nZinc, expressed as Zn\nmg/l\n< 0,5\nCopper, expressed as Cu\nmg/l\n< 0,3\nChromium, expressed as Cr\nmg/l\n< 0,3\nCadmium, expressed as Cd\nmg/l\n< 0,05\nTin, expressed as Sn\nmg/l\n< 0,5\nNickel, expressed as Ni\nmg/l\n< 0,5\nAmmonia, expressed as NH4\nmg/l\n< 10\nBoron, expressed as B\nmg/l\n< 1 – 3\nPhenol\nmg/l\n< 1",
