Division Abatement efficiencies
United Kingdom
In the case of total organic carbon (TOC), chemical oxygen demand (COD), total nitrogen (TN) and total inorganic nitrogen (Ninorg), the calculation of the average abatement efficiency referred to in these BAT conclusions (see Table 1 and Table 2) is based on loads and includes both pretreatment (BAT 10 c) and final treatment (BAT 10 d) of waste water.
