Kovalova, Lubomira published the artcileElimination of Micropollutants during Post-Treatment of Hospital Wastewater with Powdered Activated Carbon, Ozone, and UV, Quality Control of 117-96-4, the main research area is micropollutant posttreatment hospital wastewater powd activated carbon ozone UV.
A pilot-scale hospital wastewater treatment plant consisting of a primary clarifier, membrane bioreactor, and 5 post-treatment technologies including O3, O3/H2O2, powd. activated C (PAC), and low pressure UV light with and without TiO2 was operated to test the removal efficiencies for 56 micropollutants. The extent of the removal of the selected micropollutants (pharmaceuticals, metabolites and industrial chems.) was correlated to phys.-chem. properties or mol. structure. By mass loading, 95% of all measured micropollutants in the biol. treated hospital wastewater feeding the post-treatments consisted of iodinated contrast media (ICM). The removal of ICM by the tested post-treatment technologies was 50-65% when using 1.08 g O3/g DOC, 23 mg/L PAC, or a UV dose of 2400 J/m2 (254 nm). For the total load of analyzed pharmaceuticals and metabolites excluding ICM the removal by ozonization, PAC, and UV at the same conditions was 90, 86, and 33%, resp. Thus, the majority of analyzed substances can be efficiently eliminated by ozonization (which also provides disinfection) or PAC (which provides micropollutants removal, not only transformation). Some micropollutants recalcitrant to those 2 post-treatments, such as the ICM diatrizoate, can be substantially removed only by high doses of UV (96% at 7200 J/m2). The tested combined treatments (O3/H2O2 and UV/TiO2) did not improve the elimination compared to the single treatments (O3 and UV).
Environmental Science & Technology published new progress about Adsorptive wastewater treatment. 117-96-4 belongs to class isoquinoline, name is Diatrizoic Acid, and the molecular formula is C11H9I3N2O4, Quality Control of 117-96-4.
