“…After this ozonation process, the chlorination of low molecular organic structures yields HAA in water. Recently, many researchers determined that the hydrophilic fraction of water is the precursor to HAAs (Kim et al 2006). Therefore, the highest mean HAA 5 level was that in BTP.…”

A sampling program was conducted to investigate the formation of disinfection by-products (DBPs) and dissolved organic carbon (DOC) at two advanced water treatment plants in Kaohsiung City, Taiwan. The results in this study can be used as a reference for the operational control of water treatment plants and the setting of regulations in Taiwan. Samples of drinking water were collected from two advanced water treatment plants from June 2007 to April 2008. Changes in the concentration of dissolved organic carbon, the trihalomethane formation potential, and the haloacetic acids formation potential were measured in raw water samples. Variations in the concentrations of trihalomethanes (THMs) and haloacetic acids (HAA(5)) in finished drinking water were evaluated. The major species of HAA(5) were in the order of dichloroacetic acid and trichloroacetic acid and the THM was of trichloromethane. DOC was strongly related to DBPs in raw water. In this investigation, the removal efficiency of DBPs in Plant A (ultrafiltration/reverse osmosis system) exceeded that in Plant B (ozonation/biological activated carbon system). Both advanced water treatment plants greatly improved the quality of drinking water.

“…A spektrumból ekkor megállapítható a különbözı kémiai eltolódású jeleket létrehozó protonok számaránya, mivel egy molekula jeleinek integráljai arányosak az ıket létrehozó protonok számával. A negyedik sáv (6-8,5 ppm) protonjai aromás vagy olefin szénatomhoz kötıdnek (Leenheer et al, 1997;Kim et al, 2006). NMR mérések kiértékelése során ritkán vizsgálják a meghatározás pontosságát, azonban humuszanyagok esetén a fázisolás nem mindig egyértelmő, így célszerő szórás értéket megadni (Malcolm, 1990).…”

Kim et al (2006) (Noyes & Leenheer, 1989;Thorn, 1989). Ennek oka egyrészt a különbözı mérési körülmények és beállítások, másrészt a sokféle kémiai környezetben lévı protonok jelei átlapolódnak az egyes régiókon belül, így csak közelítı tartományok jelölhetık ki.…”

BACKGROUNDAfter biological treatment, coking wastewater contains high concentrations of toxic organic contaminants and thus requires further treatment.RESULTSAdvanced treatment of biotreated coking wastewater (BTCW) with peroxymonosulfate (PMS) oxidation catalyzed by granular activated carbon (GAC) at ambient temperature (25 °C) was comprehensively investigated. The GAC/PMS system exhibited higher efficiency for total organic carbon (TOC) removal from BTCW than did the PMS‐only and GAC‐only systems. Up to 75.7% of TOC was removed over a 5 h period with 2 g L‐1 of KHSO5 and 10 g L‐1 of GAC at an initial pH of approximately 5. The TOC removal efficiency increased with PMS concentration and GAC dosage; however, the superfluous PMS was not conducive to organic degradation. The PMS decomposition followed a first‐order kinetics behavior. The GAC/PMS system's capacity for TOC removal gradually weakened with increase in the number of times the GAC was reused. Almost half of the removal rate was retained after four uses of GAC. The excitation–emission matrix fluorescence demonstrated that humic‐acid‐like substances are effectively adsorbed and preferentially decomposed in wastewater.CONCLUSIONThe study suggests that it is feasible for advanced treatment of BTCW with PMS oxidation catalyzed by GAC, achieving high efficiency for TOC removal. © 2017 Society of Chemical Industry
