Mechanistic Investigation of Haloacetic Acid Reduction … Carbon-Ti4O7 composite reactive electrochemical membranes REMs were studied for adsorption and electrochemical reduction of haloacetic acids HAAs . Powder activated carbon PAC or multiwalled carbon nanotubes MWCNTs were used in these composites. Results from flow-through adsorption experiments with dibromoacetic acid DBAA as a model HAA were interpreted with a transport …

Removal of haloacetic acids by ozone and biologically … Haloacetic acids are recognized as carcinogens. They are naturally formed on the surface of water or as disinfection by-products of drinking water during the chlorination process. The efficiency of an integrated treatment system combining ozonation and biological activated carbon BAC was examined for the removal of five regulated haloacetic acids, namely, chloroacetic, dichloroacetic, trichloroacetic, …

Removal of haloacetic acids by ozone and biologically active carbon & 0183;& 32;PDF 文件combining ozonation and biological activated carbon BAC was examined for the removal of five regulated haloacetic acids, namely, chloroacetic, dichloroacetic, trichloroacetic, bromoacetic, and dibromoacetic acid known collectively as HAA 5 , in synthetic water. The effects of ozone dosage, contact time during the ozonation process, and the empty bed contact time EBCT of the BAC …

Removal of Trihalomethanes and Haloacetic Acids from … 18/01/2014 & 0183;& 32;This study investigated the use of biological activated carbon filters BACF to reduce the amounts of disinfection by-products DBPs in treated drinking water in a water treatment plant. To accomplish this, experiments were conducted in a pilot-scale treatment system to evaluate the removal of trihalomethanes THMs and haloacetic acids HAAs by BACF. The results showed that BACF …Cited by: 6

Disinfection by-product formation potential of ... - … The correlations between DBPFPs and dissolved organic carbon concentration or ultraviolet absorbance at 254 nm UV 254 were also investigated to predict DBPFPs. Among DBPFPs, which were higher at the death phase, the formation potential FP of haloacetic acid was the highest. In addition, the high relative haloacetonitrile FP at the death phase indi ed that a relevant portion of the intracellular …Author: Keun-Young Park, Keun-Young Park, Su-Young Choi, Sun-kyung Ahn, Ji-Hyang Kweon

Adsorption of Humic acid on Powdered Activated Carbon PAC & 0183;& 32;PDF 文件Removal capacity and rate of Humic Acid HA onto powdered activated carbon PAC were studied at constant room temperature which is 24-25. o. C by using tap water as a solvent. If enough PAC is added to solution, maximum HA removal efficiency of PAC which is more than 99% is observed, and adsorption uptake was found almost 22.5 mg HA/g PAC for 90% removal of HA. And also, almost 90% of HA …
