“…As an example, hydrophobic fraction is more reactive with chlorine while hydrophilic fraction is reactive to bromine and iodine in water to form DBPs. Nevertheless, Lu et al, (2009) reported that aromatic carbon content in NOM was the main surrogate to DBPs formation in chlorination process regardless of its hydrophobicity nature. Therefore hydrophobic acid recorded the highest DBPs formation during the treatment .…”

“…Generally the formation of DBPs is dependent on several factors during the treatment such as disinfectant concentration, contact time, pH, temperature and NOM properties and concentration (Lu et al, 2009;Yee et al, 2009;Hong et al, 2007;Nikolaou, and Lekkas, 2001). Increasing in these factors will increase the formation of DBPs during the treatment.…”

“…The use of alternative disinfectant such as ozone, chlorine dioxide and chloramine disinfectants was able to reduce major DBPs formed by chlorine. Unfortunately these disinfectants also formed its specific DBPs and occurred at higher level (Lu et al, 2009;Krasner et al, 2006). According to Krasner et al (2006) about 600 new DBPs form from a reaction of NOM with disinfectants such as chlorine, chloramine, ozone, and chloride which found in drinking water by the year 2006 and 70% of halogenated DBPs reported are unidentified.…”

Abstract. Natural organic matter (NOM) can be defined as a mixture of complex organic compounds that universally present in natural waters. High NOM content in water strongly impact the water quality and treatment in several ways (e.g. causing colour and odour, filter fouling and increase coagulant dose). Besides that, NOM also acts as the main precursor to disinfectant by products (DBPs) produce from the reaction of NOM and disinfectant during water treatment. DBPs are known to be carcinogenic to human and animals. The formation of DBPs is depending on NOM characteristics. Generally, NOM characteristics are differ according to the water sources. In order to understand NOM properties, NOM fractionation is required and therefore different approaches have been proposed for its characterization. Meanwhile several methods of treatment have been developed to remove or reduce the amount of NOM in drinking water sources to prevent DBPs formation. The aim of this paper is to review and discuss the properties and available treatment techniques for NOM.

“…Although many conventional methods have been applied in removing organic contaminants, those methods do not lead to total mineralisation of the pollutants. Moreover, further treatment is needed since the methods employed are unable to convert the pollutants into harmless products such as CO 2 and H 2 O, which indirectly increases the operational cost (Allegre, Maisseu, Charbit, & Moulin, 2004;Gaya & Abdullah, 2008;Lu, Zhang, Ma, & Chen, 2009;Padmanabhan et al, 2006;Yang & Cheng, 2007). Therefore, the development of an efficient wastewater treatment solution is imperative.…”

ZnO/γ-Fe 2 O 3 nanocomposite was synthesized via simple precipitation. The synthesized nanocatalysts underwent heat treatment at 450 o C for an hour. The characteristics of the nanocomposite were investigated by XRD, TEM, and BET surface area measurement. Zeta potential analysis was used to examine the surface charge properties of the nanocatalysts. The synthesized nanocomposite has an average particle size of 11 nm and a surface area of 20 m 2 g -1 . The potential of ZnO/γ-Fe 2 O 3 as a photocatalyst was evaluated by photodegrading chlorophenoxyacetic acids (PAA, 2,4-D, 2,4,5-T and 4CA). The decomposition of chlorophenoxyacetic acids by ZnO/γ-Fe 2 O 3 followed 4CA > 2,4,5-T ≈ 2,4-D > PAA. The result indicates the applicability of ZnO/γ-Fe 2 O 3 nanocomposite as a photocatalyst in removing organic pollutants in wastewater.

“…The results of several studies have shown monochloramine to be effective at limiting TTHM formation overall [33][34][35][36], although a study by Hua and Reckhow [37] indicates that this effectiveness may decrease slightly with increased bromine substitution. However, this decreased effectiveness may only occur under very high bromide concentrations.…”

Significant fractions of bromine-substituted disinfection byproducts (DBPs)-particularly trihalomethanes (THMs)-have been observed to form during treatment of water from the Missouri River. THM speciation was also noted to follow a seasonal pattern during a 2.5-year period, during which samples were collected multiple times per month. Although some treatment processes were effective at reducing the chloroform formation potential, no treatment used at this utility significantly reduced the formation of the three bromine-substituted THM species. Using chloramination rather than free chlorination for secondary disinfection, however, was effective at limiting increases in the concentration of all four regulated THM species in the distribution system.
