Pilot-scale trials of four different pre-treatments to ceramic membranes were performed for a surface water in southwest England. A study of the organic character of the feed and treated waters by liquid chromatography-organic carbon detection (LC-OCD) provided an indication of which fraction of organics was contributing to fouling. It appears that the large molecular weight organics, identified as biopolymers by LC-OCD, contributed to fouling when ion exchange was used as pre-treatment, and coagulation is also needed to help control fouling for the source waters of this study.

Just as with chlorination, medium-pressure (MP) ultraviolet (UV) treatment applied for disinfection purposes has been found to cause formation of genotoxic compounds, measured by the Ames test. By lowering the nitrate and dissolved organic carbon (DOC) content, the Ames test response was reduced substantially. The impact of nitrate photolysis on formation of genotoxic compounds was confirmed. A representative organic micropollutant selection had no significant impact on the Ames test response. Formation of genotoxic compounds was found after MP UV disinfection, photolysis, and advanced oxidation of pretreated groundwater. In addition to nitrate and DOC content, aromaticity of organic matter had a strong impact. Ames test responses were converted into 4-nitroquinoline oxide (4-NQO) equivalent concentrations to enable quantitative comparison and to apply simple risk assessment. Based on the threshold for toxicological concern, already at doses applied for MP UV disinfection, the 4-NQO equivalent concentration of formed genotoxic compounds in nitrate-rich water exceeded the limit of no risk. © 2015 American Water Works Association.

Assessment of drinking-water biostability is generally based on measuring bacterial growth in short-term batch tests. However, microbial growth in the distribution system is affected by multiple interactions between water, biofilms and sediments. Therefore a diversity of test methods was applied to characterize the biostability of drinking water distributed without disinfectant residual at a surface-water supply. This drinking water complied with the standards for the heterotrophic plate count and coliforms, but aeromonads periodically exceeded the regulatory limit (1000 CFU 100 mL-1). Compounds promoting growth of the biopolymer-utilizing Flavobacterium johnsoniae strain A3 accounted for c. 21% of the easily assimilable organic carbon (AOC) concentration (17 ± 2 μg C L-1) determined by growth of pure cultures in the water after granular activated-carbon filtration (GACF). Growth of the indigenous bacteria measured as adenosine tri-phosphate in water samples incubated at 25 °C confirmed the low AOC in the GACF but revealed the presence of compounds promoting growth after more than one week of incubation. Furthermore, the concentration of particulate organic carbon in the GACF (83 ± 42 μg C L-1, including 65% carbohydrates) exceeded the AOC concentration. The increased biomass accumulation rate in the continuous biofouling monitor (CBM) at the distribution system reservoir demonstrated the presence of easily biodegradable by-products related to ClO2 dosage to the GACF and in the CBM at 42 km from the treatment plant an iron-associated biomass accumulation was observed. The various methods applied thus distinguished between easily assimilable compounds, biopolymers, slowly biodegradable compounds and biomass-accumulation potential, providing an improved assessment of the biostability of the water. Regrowth of aeromonads may be related to biomass-turnover processes in the distribution system, but establishment of quantitative relationships is needed for confirmation. © 2015 Elsevier Ltd.

The degradation kinetics of three pesticides - metaldehyde, clopyralid and mecoprop - by ultraviolet photolysis and hydroxyl radical oxidation by low pressure ultraviolet hydrogen peroxide (LP-UV/H2O2) advanced oxidation was determined. Mecoprop was susceptible to both LP-UV photolysis and hydroxyl radical oxidation, and exhibited the fastest degradation kinetics, achieving 99.6% (2.4-log) degradation with a UV fluence of 800 mJ/cm2 and 5 mg/L hydrogen peroxide. Metaldehyde was poorly degraded by LP-UV photolysis while 97.7% (1.6-log) degradation was achieved with LP-UV/H2O2 treatment at the maximum tested UV fluence of 1000 mJ/cm2 and 15 mg/L hydrogen peroxide. Clopyralid was hardly susceptible to LP-UV photolysis and exhibited the lowest degradation by LP-UV/H2O2 among the three pesticides. The second-order reaction rate constants for the reactions between the pesticides and OH-radicals were calculated applying a kinetic model for LP-UV/H2O2 treatment to be 3.6 × 108, 2.0 × 108 and 1.1 × 109 M-1 s-1 for metaldehyde, clopyralid and mecoprop, respectively. The main LP-UV photolysis reaction product from mecoprop was 2-(4-hydroxy-2-methylphenoxy) propanoic acid, while photo-oxidation by LP-UV/H2O2 treatment formed several oxidation products. The photo-oxidation of clopyralid involved either hydroxylation or dechlorination of the ring, while metaldehyde underwent hydroxylation and produced acetic acid as a major end product. Based on the findings, degradation pathways for the three pesticides by LP-UV/H2O2 treatment were proposed. © 2016 Elsevier Ltd.

Ceramic membrane technology is known for its robustness of the ceramic membranes, but ceramic membrane systems have historically been too costly for installation in drinking water treatment plants, primarily due to the traditional configuration of each membrane module being housed in individual stainless steel casings, which is costly. PWN Technologies (PWNT) has developed a different ceramic membrane system configuration, called the CeraMac® which greatly reduces the capital cost by housing up to 200 modules in a single, stainless steel vessel. PWNT, together with PUB, Singapore's National Water Agency, has embarked on a rigorous and systematic evaluation of the newly developed CeraMac® system at the Choa Chu Kang Waterworks (CCKWW). The demonstration plant testing began with coagulated and clarified feed water from the existing CCKWW. The findings of this phase of testing were that the CeraMac® system can operate with a flux of 200 lmh, a backwash interval of 30 minutes, and an enhanced backwash interval of once every 30 backwashes when treating clarified water. Membrane permeability was stable at approximate 325 lmh/bar at a water recovery of 96.88%. In this phase, fluctuations of transmembrane pressure (TMP) and permeability were also observed, mainly owing to changes in feed water quality. In a second phase of the demonstration study, ozone was applied to the clarified feed water to investigate the effect on membrane operational performance. The results of these tests exceeded expectations. The combination of ozone with CeraMac® significantly improved the system's performance, with stable operation, lower TMP, increased permeability, and increased recovery. The CeraMac® system operated with a flux of >240 lmh, a backwash interval of 180 minutes, and an enhanced backwash interval of once every 4 backwashes when treating ozonated clarified water. A membrane permeability of 850 lmh/bar and a water recovery of 99.3 % were achieved. This flux was the maximum that could be achieved by the equipment that was installed in the demonstration plant. © 2013 American Water Works Association.

An extensive pilot study of ceramic microfiltration (MF) in the Ceramac® configuration for treating IJssel Lake water was conducted at a demonstration-scale. There were two phases of research. The first phase was start up, commissioning, troubleshooting, and preliminary performance evaluation of Ceramac® system. In the second phase, the Ceramac® system was operated at conditions that would be used for the full-scale design. At a gross flux of 75 LMH, a backwash interval of 30 minutes, and a chemically enhanced backwash after the 11th backwash, a nearly constant specific flux of about 500 LMH/bar (corrected to a temperature of 10 degrees Celsius) was observed during the three month testing period. After the ceramic MF, UV transmission (UVT) increased from 89.0 percent (feed water) to 93.1 percent (filtrated water), on average. The pilot study results show the Ceramac® is feasible and reliable pretreatment technology for IJssel Lake water, and that a target UVT of 92% for the downstream advanced oxidation process (i.e., UV and hydrogen peroxide) could be achieved. © 2013 American Water Works Association.
