In this case, a high stoichiometric ratio (reagent/pollutant) is applied and a significant solid waste stream is generated.\nThe conversion factor reported in Table 2 (2,5 × 10–3) has been applied.\nParameter\nBAT-AEL\nmg/Nm3\nkg/tonne melted glass\nSelenium compounds, expressed as Se\n1 – 3\n2,5 – 7,5 × 10–3",
