  "heading": "In order to reduce the load of chlorinated compounds discharged to further waste water treatment and to reduce emissions to air from the waste water collection and treatment system, BAT is to use hydrolysis and stripping as close as possible to the source.",
  "text": "Description:\nFor the description of hydrolysis and stripping, see Section 12.2. Hydrolysis is carried out at alkaline pH to decompose chloral hydrate from the oxychlorination process. This results in the formation of chloroform which is then removed by stripping, together with EDC and VCM.\nBAT-associated environmental performance levels (BAT-AEPLs): See Table 10.3.\nBAT-associated emission levels (BAT-AELs) for direct emissions to a receiving water body at the outlet of the final treatment: See Table 10.5.\nTable 10.3\nBAT-AEPLs for chlorinated hydrocarbons in waste water at the outlet of a waste water stripper\nThe average of values obtained during 1 month is calculated from the averages of values obtained during each day (at least three spot samples taken at intervals of at least half an hour).\nParameter\nBAT-AEPL(average of values obtained during 1 month)\nEDC\n0,1–0,4 mg/l\nVCM\n< 0,05 mg/l\nThe associated monitoring is in BAT 79.",
