“…It is the fact that disinfection is indispensable, but the elimination of by‐products is also crucial. Gold nanocrystals are widely used for disinfecting by‐products due to their catalytic reduction, 23 therefore, the separation of the accumulated Au nanoparticles after disinfecting process should not be ignored. Except for the protein resistance of membrane, the rejection of nanoparticle is another important parameter to estimate the property of membrane in the water treatment.…”

To endow polyethersulfone (PES) membranes with enhanced hydrophilicity and antiprotein adsorption performance, amphiphilic dithiolane-containing copolymers poly[poly (ethyleneglycol)methylethermethacrylate-co-2-(methacryloyloxy)ethyl 5-(1,2-dithiolan-3-yl)pentanoate-co-(4-formylphenyl)-2-methylprop-2-enoate]{abbr. Poly(MAPEG-co-MALA-co-MAHA)} with different polymerization degree were successfully synthesized, and then blended with PES to prepare microfiltration membranes by immersion precipitation phase inversion process. The chemical structure and molecular weight of poly(MAPEG-co-MALA-co-MAHA) were characterized by NMR, FTIR and GPC. The morphology and surface property of the as-prepared blending membranes were also characterized by SEM, AFM and contact angle testing etc. Compared with pure PES membrane, the contact angle of PES/poly(MAPEG-co-MALA-co-MAHA) membranes decreased from 74.2 to 53.7 , and the bovine serum albumin (BSA) adsorption declined from 121.4 to 58.8 μg cm −2. Meantime, the water flux of PES/poly(MAPEG-co-MALAco-MAHA) membranes increased from 38.6 to 89.1 L m −2 h −1 , the flux recovery ratio increased from 68.3% to 93.3% and the irreversible flux decline ratio decreased from 31.7% to 6.7%. Furthermore, the mechanical property of PES/poly(MAPEG-co-MALAco-MAHA) membrane was better than that of pure PES membrane. In addition, the rejection of BSA and Au nanoparticle reached 77.3% and 66.2% respectively. The results showed that the addition of poly(MAPEG 18-co-MALA 18-co-MAHA 18) with tiny amount could not only improve the hydrophilicity and antifouling of the membrane, but also endow the microfiltration membrane with the rejection of nanoparticles.

“…S ince the early 20th century, the disinfection of drinking water successfully protected public health and it also reduced the morbidity of waterborne diseases including amoebic dysentery, cholera, and typhoid fever (Dong, Li, He, Chen, & Mao, ; Dong, Li, Lin, & Duan, ; Li et al, ; Selma & Panagiotis, ). As we all know, chlorine is effective in deactivating pathogens; however, it would lead to concern about the formation of disinfection by‐products (DBPs) (Dong, Li, Crittenden, et al, ; Du et al, ; Li et al, ). The reactions between natural organic matter (NOM) and oxidants would form the DBPs in drinking water (Jones, Saglam, Song, & Karanfil, ).…”

In this study, we investigated the control efficiency of a wide variety of disinfection by-products (DBPs) (including trihalomethanes [THMs], haloacetic acids [HAAs], haloacetonitiles [HANs], haloketones [HKs], haloaldehydes [Has], and trihalonitromethanes [THNMs]) with different drinking water treatment processes including pre-ozonation, coagulation-sedimentation, sand filtration, and ozone combined with biological activated carbon (O 3 -BAC) advanced treatment processes. The assessment of the treatment efficiency regarding the removal of organic matter was measured by the excitation emission matrix (EEM) spectra. There was a superior efficiency in reducing the formation of DBPs and their precursors by different drinking water treatment processes. Though some DBPs such as THMs could be promoted by ozonation, these by-products from ozonation could be degraded by the following BAC filtration process. In addition, the organic matter from the aromaticity, fulvic acid-like, protein, and soluble microbial by-products-like regions could be further degraded by the O 3 -BAC treatment.

“…The chlorination process is a very efficient way for water disinfection for public supply, providing among other benefits, the reduction of infant mortality due to enteric diseases [1] [2]. However, there is the disadvantage of forming undesirable products called halogen compounds, such as trihalomethanes (THMs), haloacetic acids, halopicrins, cyanogen chloride, among many others [3] [4].…”

Chlorination is an efficient and low-cost technique in disinfecting water for public water supply. However, during the process, the formation of undesirable by-products called halogen compounds, such as trihalomethanes (THMs), occurs. Some of these compounds are proven to be carcinogenic to laboratory animals. The goal of this study was to investigate the occurrence of THMs in household reservoirs and the influence of cleaning time of these reservoirs on the formation of THMs. A total of 103 households were investigated in the city of Maringá, State of Paraná, Brazil. The residences were classified according to the cleaning time of the reservoir into: up to one year, one to two years and more than two years. Samples were taken from the reservoirs and total trihalomethanes (THMt) were analyzed by gas chromatography (GC-MS), total organic carbon (TOC) by means of a Hach kit for low concentrations and free residual chlorine (CLres) by means of a kit for in loco determination. According to the results, the highest concentrations of THMt were observed in the reservoirs with cleaning time of more than 2 years. However, no amount has exceeded the maximum limit allowed by law. In general, the longer the time for cleaning the reservoir, the greater the degradation of water quality in THMt.
