31. Effect of preozonation on wastewater reclamation by the combination of ozonation and soil aquifer treatment

Author

Echigo, S., Nakatsuji, M., Takabe, Y., Itoh, S., Echigo, S., Nakatsuji, M., Takabe, Y., and Itoh, S.

Abstract

A series of column experiments and risk evaluation showed that preozonation was a better option to enhance the performance of soil aquifer treatment (SAT) than ozonation after SAT with respect to dissolved organic carbon, trace organic contaminants, and disinfection byproducts. This is a good example to show that upgrading pretreatments can be more effective than adding extra treatments after SAT, and that it is important to optimize a water reclamation system as a whole system.

32. Reduction of chlorinous odor by the combination of oxidation and ion-exchange treatments

Author

Echigo, S., Itoh, S., Ishihara, S., Aoki, Y., Hisamoto, Y., Echigo, S., Itoh, S., Ishihara, S., Aoki, Y., and Hisamoto, Y.

Abstract

To better control chlorinous odor in tap water, we assessed the performance of the combination of oxidation (ozonation or advanced oxidation processes, AOP) and ion-exchange treatment. In this process, the hydrophilic neutral fraction (a major dissolved organic matter (DOM) fraction) is converted to ionic species, and these ions and ammonium ion are effectively removed during ion-exchange processes. We found that each treatment process (e.g., oxidation alone or ion exchange alone) was effective for the reduction of chlorinous odor to some extent, but the chlorinous odor formation potential was lower when the oxidation process and ion exchange were applied in series. The combination of AOP (ozone/vacuum ultraviolet treatment) at a high ozone dose and ion exchange (both cation and anion) was most effective, and the chlorinous odor formation potential was reduced to approximately 30 TON (threshold odor number) from more than 100 TON. Also, dissolved organic carbon and ammonium ion were effectively removed with this process. Compared with ozonation, AOP was more effective at a higher ozone dose. The effectiveness of this process was also confirmed in continuous mode by pilot-scale experiment.

36. Effects of ion-exchange treatment on bromate formation and oxidation efficiency during ozonation

Abstract

Ion-exchange treatment is a promising technique for removing hydrophilic compounds during drinking water treatment. In this study, we applied several different ion exchangers (i.e., anion exchange resins and a hydrotalcite compound) to bromide removal to minimize bromate formation during ozonation. It was found that ion-exchange treatment affected ozone and hydroxyl radical concentration profiles as well as bromate ion concentration after ozonation. Selecting an appropriate ion exchanger is important to achieve both the oxidation of target contaminants and the reduction of bromate ion during ozonation.

37. Profiles of dissolved organic matter and haloacetic acid formation potential in drinking water treatment by a comprehensive fractionation technique

Abstract

A comprehensive fractionation technique was applied to a set of water samples obtained along a real drinking water treatment plant with ozonation and granular activated carbon (GAC) treatment to obtain detailed profiles of dissolved organic matter (DOM) and to evaluate the haloacetic acid (HAA) formation potentials of these DOM fractions. The results indicated that ozonation and GAC treatment showed limited ability to remove hydrophilic fractions (23%), while removal of hydrophobic fractions was 72%. The contribution of hydrophilic fractions to HAA formation increased from 30 to 61% along the treatment train because of better removal for hydrophobic fractions both in concentration and reactivity. Similar trends were also found for trihalomethanes.

38. Evaluation of Control Strategies for Disinfection Byproducts for Small Water Supplies Using Ozone as an Alternative Disinfection Process

Author

Echigo, S., Zhang, X.R., Lei, H., Smith, M.E., Minear, R.A., Echigo, S., Zhang, X.R., Lei, H., Smith, M.E., and Minear, R.A.

Abstract

Batch ozonation experiments were conducted to investigate the effects of various operating options (i.e. additions of acid, ethanol, ammonium ion, and hydrogen peroxide) on the formation of disinfection byproducts (DBPs) in six different source waters. Formation of bromate, total organic bromines, total aldehydes (the sum of 13 aldehydes) was evaluated, assuming they represent three different types of DBPs during ozonation (i.e. inorganic bromine DBPs, organobromine DBPs, and non-brominated organic DBPs, respectively). Among the tested options, acid addition was found to be the best one to control all the three types of DBPs simultaneously on an ozone exposure basis. © IWA Publishing 2009.

Abstract

We present measurements of νμ disappearance in K2K, the KEK to Kamioka long-baseline neutrino oscillation experiment. One hundred and twelve beam-originated neutrino events are observed in the fiducial volume of Super-Kamiokande with an expectation of 158.1+9.2

Abstract

The effects of temperature and addition of OH radical scavengers/enhancers or HOBr scavenger on the formation of bromoorganic disinfection byproducts (DBPs) from ozonation of six raw waters were studied in true batch reactors. The formation of bromoorganic DBPs during ozonation generally increased with the increase of temperature, but might also decrease for the waters with somewhat higher values of specific UV absorbance (SUVA). The addition of hydrogen peroxide, ethanol, or ammonium dramatically decreased the formation of bromoorganic DBPs; t-butanol addition significantly increased the formation of bromoorganic DBPs; bicarbonate addition might increase or decrease bromoorganic DBP formation depending on the water source. For all the waters treated with the chemical addition, the level of total organic bromine (TOBr) varied with the same pace as that of ozone exposure (CT), which suggests that TOBr formed during ozonation may be used to estimate the CT, a measure for the achieved degree of disinfection. The results demonstrate that for each water, the correlation between TOBr and CT was less affected by the change of chemical composition of the water than that between BrO 3 - and CT; for a given chemical composition and temperature of a water, there generally were well-defined relationships between TOBr and CT, and bromoform and CT just as that between BrO 3 - and CT. The possible mechanisms behind the linear functions of TOBr or BrO 3 - versus CT were given. Further study is needed to examine whether the trends found in this research can be applicable for the high SUVA waters. © 2004 Elsevier Ltd. All rights reserved.
