Main Terms AMR=Actual mass removal of Table 8 and/or Table 9 compounds achieved by treatment process or a series of treatment processes, kg/hr. C=Concentration of Table 8 and/or Table 9 compounds in wastewater, ppmw. CG=Concentration of TOC (minus methane and ethane) or total organic hazardous air pollutants, in vented gas stream, dry basis, ppmv. CGc=Concentration of TOC or organic hazardous air pollutants corrected to 3-percent oxygen, in vented gas stream, dry basis, ppmv. CGS=Concentration of sample compounds in vented gas stream, dry basis, ppmv. E=Removal or destruction efficiency, percent.

MW=Molecular weight, kg/kg-mole. n=Number of compounds. p=Number of runs. %O2d=Concentration of oxygen, dry basis, percent by volume. Q=Volumetric flowrate of wastewater, m3/hr. QG=Volumetric flow rate of vented gas stream, dry standard, m3/min. QMG=Mass flowrate of TOC (minus methane and ethane) or organic hazardous air pollutants, in vented gas stream, kg/hr. QMW=Mass flowrate of Table 8 and/or Table 9 compounds in wastewater, kg/hr. ρ=Density, kg/m3. RMR=Required mass removal achieved by treatment process or a series of treatment processes, kg/hr. tT=Total time of all runs, hr. Subscripts a=Entering. b=Exiting. i=Identifier for a compound. j=Identifier for a sample. k=Identifier for a run. m=Number of samples. n=Number of compounds. p=Number of runs. T=Total; sum of individual.
