Full-Scale PACT Systems Full-Scale PACT for Industrial Effluents PACT for Co-treatment of Domestic and Industrial. In general, the pilot-scale filter performance was representative of full-scale filter performance, especially in regards to THM precursor and chlorine demand removal. Statistical evaluation and interpretation of the data for HAA and NDMA precursor removal was more difficult, likely due to the low concentrations of these DBPs which was near Cited by: 3.

Assesses the optimization of GAC to remove trihalomethane precursors (to attain finished water THM concentration of 1 - 20 µg/L), based on modeling, bench-scale, and pilot-plant experimentation. Evaluates the economics of the process by developing cost estimates for six participating utilities. Published in

The produced activated carbons under both physical and chemical activation processes were characterised with respect to their texture and surface chemistry.

The textural and chemical analyses showed that the nature of the precursor played a crucial role in determining the main characteristics of the activated carbon that was by: 7.

Catalytic ozonation followed by biofiltration significantly improved the removal efficiency of the THM and HAA9 precursors as compared to that of ozonation alone. However, the removal efficiencies of the THM and HAA9 precursors slightly increased when the catalyst dosage was increased from to gL − 1 after biofiltration.
