A comparison of adsorption of organic micropollutants onto activated carbon following chemically enhanced primary treatment with microsieving, direct membrane filtration and tertiary treatment of municipal wastewater

The limits of quantification (LOQ) and relative standard deviation (RSD) for the analysis of the 12 investigated organic micropollutants. Molecular properties of the 12 investigated organic micropollutants. Removal of DOC for each dose of PAC in the four wastewater matrices as single measurements. Concentration of wastewater constituents in the four matrices reference tubes for the PAC experiment as single measurements. Removal of micropollutants by GAC filtration and the estimated adsorbed amount (q) of micropollutants at 23000 bed volumes. Organic micropollutant adsorption onto PAC in the four wastewater matrices and best-fit isotherms using the Freundlich model. Organic micropollutant removal by adsorption vs PAC dose normalized for the DOC concentrations in four different wastewater matrices. Organic micropollutant removal by adsorption vs PAC dose normalized for the UVA254 in four different wastewater matrices.
