Diuron, gabapentin, sulfamethoxazole, terbutryn and terbuthylazine are emerging micro-pollutants with concentrations in water and wastewater ranging from tens of ng/L to > 10 μg/L levels. The Fenton oxidation catalysed either by zero-valent iron (Fe(0)) or by Fe(II) salts was studied to treat the targeted micro-pollutants and their mixtures at compound concentrations between 1 and 1000 µg/L. The Fe(0)-catalytic Fenton oxidation exhibited complete degradation of all micro-pollutants at initial solution pH 3 but at pH 5, the degradation was 90% for diuron, 80% for gabapentin, 95% for sulfamethoxazole, 100% for terbutryn and 70% for terbuthylazine, respectively. Moreover, dissolved organic carbon in multiple micro-pollutant solutions can be reduced by 70% at pH 3 and 46% at pH 5, which were much better than Fe(II)-catalytic Fenton reaction for the same pH conditions. SEM/EDX analysis showed the corrosion of iron surface and FTIR analysis evidenced the adsorption of oxidation by-products onto solid iron surface. Additionally, the toxicity of effluent after the treatment was reduced to minimal and the Behnajady-Modirshahla-Ghanbery (BMG) model fitted well to the kinetics of the mineralisation of the studied micropollutants. Finally, Fe(0) catalyst can be reused up to three times and the process produced no or less sludge at pH 3 and pH 5, respectively. The impact of this study is that the Fe(0)-catalytic Fenton oxidation would be an alternative to the traditional Fenton reaction to combat the environmental issues caused by the emerging micro-pollutants.

Bisphenol-S (BS) has recently raised public concerns for its adverse effect on the health safety and ecological security. BS concentrations were detected in many water resources, ranging from 10 ng L−1 to 300 μg L−1, so that various purification techniques have been sought to remove BS. This study investigated the performance of ozonation and ferrate oxidation in the degradation of BS since they are both promising oxidants with high redox potential among water treatment chemicals. It was observed that both ozone and ferrate can achieve over 99% of BS concentration reduction and up to 22.5% of DOC reduction for dosing 0.036 mM of either ferrate or ozone. The vibrio fisheri toxicity exhibited a decline in the treated samples after ozonation or ferrate oxidation. According to the mass spectra analyzed, the degradation pathways were proposed and oxidation products (OPs) were identified. BS degradation by ozonation and ferrate oxidation followed a similar route and four common OPs (OP-249; OP-497-a; OP-497-b, and OP-201) were detected. While ferrate treatment produced one more intermediate (OP-217), ozonation did not, which is attributed to the intensified decomposition of BS by ozonation. The major impact of this study is that ferrate treatment is comparable to the ozonation in removing BS, and further research continuing from this study is necessary to explore the BS removal in various waters with more complex matrixes (e.g., high natural organic matter contents), to investigate BS degradation mechanisms in depth, and to conduct pilot-scale and full-scale trials to establish operational database in running ferrate oxidation and/or ozonation for the treatment of BS in practical world.

In drinking water treatment, filtration plays an important role in the multi-barrier approach employed for the removal of pathogens. The presence of suspended solids and other particulate matter in water increases the resistance of most microbes to disinfection. Therefore, high performance in the removal of particles achieved by granular filtration can increase the disinfection efficiency. Although sand is one of the major filter media, alternative media have been developed and used in recent years. In this review, the performance of alternative media is compared with traditional sand/anthracite for drinking water treatment. Advantages in the use of alternative media, especially glass media, have been found, including high filtration performance in removing residual particles and turbidity, minor modification requirements to the existing filtration configuration and slow head loss development. However, before the employment of them in industry, additional tests are recommended. In particular, full scale tests with variations in the operating conditions and analyses of pathogen removal should be performed. Moreover, this paper reviews the filtration processes and operating configurations which provide overall references to those who are studying and working in the field of water technology and treatment. In the Supplementary Materials of this paper, legislations/standards of safe drinking water are summarized as they are the driving force of developing new treatment technologies; mathematical modules for predicting the media filtration performance are briefed. Finally, future work on the application of alternative filter media is recommended.

BACKGROUND Emerging micro‐pollutants (EMPs) in water have received much attention due to their potential hazards to human health and ecological security. Ferrate has been researched in recent years to remove both particulate and dissolved impurities (including EMPs) from water, and its promising performance has been attributed to the high oxidation capacity and coagulation functions. However, limited research has compared ferrate with coagulation alone in the treatment of EMPs, which is one of the major objectives of this study. RESULTS Three emerging micro‐pollutants (EMPs), imidacloprid (IMP), bisphenol‐S (BS), and azithromycin (AZM) were chosen for this study. In all cases, ferrate outperformed to ferric chloride in the removal of the EMPs. For a given ferrate dose of 0.05 mM, 99% of BS, 85% of AZM, and 78% of IMP were removed for a start concentration of 10 μg L−1. However, if the start concentration was 1000 μg L−1, removal efficiency was decreased to 82% for BS, 62% for AZM, and 22% for IMP. pH 5 was favorable to the EMP removal by ferrate for the study conditions. Although higher removals of IMP, BS, and AZM were achieved by ferrate in comparison to those by ferric chloride, only 20% DOC removal was achieved by the ferrate. The formation of various oxidation products in the degradation process resulted in the disparity of the solution toxicity; that of BS was reduced but those of IMP and AZM increased after ferrate treatment. Nevertheless, the toxicity of ferric chloride treated samples was all increased. CONCLUSION Ferrate has higher efficiency comparing with FeCl3 to remove IMP, BS, and AZM. Degradation of the EMPs by ferrate was more efficient in acidic conditions (pH 5) and at the EMPs' lower initial concentrations for the given conditions. IMP was more resistant to the ferrate treatment compared to BS and AZM under the same conditions. Overall, 20% DOC reduction was achieved by ferrate for pH 5. Finally, the toxicity of BS can be reduced but those of IMP and AZM were increased after ferrate treatment, whilst the toxicity of ferric chloride treated samples was all increased. © 2020 Society of Chemical Industry

The work presented in this chapter was to validate whether ferrate(VI) can be used as an alternative to the existing coagulant (e.g., ferric chloride) for both drinking water and domestic sewage treatment via a series of pilot-plant trials. For drinking water treatment, a ferrate(VI) dose of 0.1 mg/L can achieve 93% and 97% particle removal (in terms of particle counting) after the filtration for the raw water and for the ozonized water, respectively, which is satisfactory to the treated water quality demand for the particle removal. Moreover, ferrate(VI) can remove 10% metformin, benzotriazole and acesulfame from raw water, but FeCl3 with ozonation cannot. When treating domestic sewage at pilot-scale trials, ferrate(VI) demonstrated encouraging performance as well; at a very low dose range, 0.1–0.2 mg Fe(VI)/L, ferrate(VI) achieved better performance in comparison with high-dosed ferric sulfate. This will reduce chemical demand and sludge production, and, therefore, it results in a low operating cost and substantial cost saving in treating sewage.

Antibiotics have been frequently detected in the environment and watercourses which can inspire bacterial resistance and create super-bacteria; resulting in potential adverse impacts on the human health and environment. This work thus investigated the synergistic effect of a combined process (ferrate(VI) oxidation with montmorillonite adsorption), in comparison with either the oxidation or adsorption alone, for the removal of one of antibiotics, sulfadiazine (SDZ). The results manifested that all the three combined processes can promote the removal of SDZ but the simultaneous oxidation and adsorption can achieve the outperforming removal of SDZ (76.20%) in comparison with the oxidation alone (60%) or adsorption alone (10%) for the same given conditions, and the synergistic effect of combined oxidation/adsorption was confirmed. Additionally, the degradation of SDZ by ferrate(VI) fitted in the pseudo-second-order reaction characteristics, and the total reaction rate constant was derived as 2.97*10-4 L2 mg-2 min-1. The study also explored the possible pathways of the SDZ degradation by ferrate(VI) and potential oxidation product formation when an incompletemineralization of SDZ was observed. The oxidation product formed was proposed as a macromolecular-like compound containing R-NO2 groups which were oxidized from the initial structure of SDZ containing R-NH2 groups.

This research aims to depict the comparative performance of micropollutants’ removal by FeSO4- and zero-valent iron (Fe(0))-catalytic Fenton oxidation and to explore the possibilities of minimising the sludge production from the process. The emerging micropollutants used for the study were gabapentin, sulfamethoxazole, diuron, terbutryn and terbuthylazine. The Taguchi method, which evaluates the signal-to-noise ratio instead of the standard deviation, was used to develop robust experimental conditions. Though both FeSO4- and Fe(0)-catalytic Fenton oxidation were able to completely degrade the stated micropollutants, the Fe(0)-catalytic Fenton process delivered better removal of dissolved organic carbon (DOC; 70%) than FeSO4 catalytic Fenton oxidation (45%). Fe(0)-catalytic Fenton oxidation facilitated heterogeneous treatment functions, which eliminated toxicity from contaminated solution and there was no recognisable sludge production.

Ozone possesses high selectivity in the oxidation of organic pollutants. It actively reacts with electron donating participants which contain π bonds and non-protonated amines groups. The removal efficiency of organic pollutants hugely depends upon the pollutants’ initial concentration and amount of ozone supplied. This study was conducted at Zweckverband Bodensee-Wasserversorgung (Lake Constance Water Supply), Germany. The prime objective of the research was to observe the performance of diuron and gabapentin ozonation for low ozone doses, therefore meeting the real application requirements of the water treatment plant. Thereby, 1 mg·L−1 of the given organic pollutants was chosen for the treatment. The ozone with a dosage of ≈0.68–1.01 mg·L−1 was generated and homogeneously mixed into Lake Constance water in a semi-batch reactor system. The adequate aliquots of diuron/gabapentin were spiked into the homogenous matrix to acquire the desired initial concentration. The effect of ozone dose and reaction time on the degradation of diuron and gabapentin was investigated. Low ozone doses were sufficient for the complete degradation of diuron and gabapentin, although satisfactory total organic carbon (TOC) reduction was not achieved. Nonetheless, the toxicity from ozone treated effluents can be avoided by adjusting treatment conditions. Due to that degradation data obtained did not follow normalization, the non-parametric (non-normalised) data were analysed with a generalised linear regression model for Gaussian and Poisson distribution. Statistical analysis showed that the ozonation treatment of diuron/gabapentin followed the Gaussian model distribution and the degradation data obtained was proven significant using the Kruskal–Wallis test.

Micro-pollutants in aquatic environment are an emerging challenge to the human health and ecosystems. This study was to investigate the acute toxicity before and after ferrate(VI) treatment for four pharmaceuticals (simvastatin, ivermectin, fluoxetine and oxytetracycline) at concentrations of 10 and 100 μg/L, respectively. Zebrafish animal model and Vibrio fischeri luminescent test were employed to achieve the study targets. It is the first effort using the stated methods to assess toxicity of the selected pharmaceuticals before and after ferrate(VI) treatment when biochemical responses of catalase (CAT), tumour necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β) and B-cell lymphoma 2 (Bcl-2) were assessed in the zebrafish model. The results firstly revealed a significant change in the gene expression of CAT (p < 0.001), TNF-α SOD 1 (p < 0.01), and Bcl-2 (p < 0.05) for simvastatin at low concentrations, which exhibited high toxicity in comparison with other pharmaceuticals. Ferrate(VI) treatment significantly reduced the toxicity of simvastatin by partially removing it during the treatment process and ferrate(VI) itself did not produce additional toxicity in the effluent.

Excess phosphorus (P) in freshwater bodies is one of the major causes of eutrophication. The regulations for removing phosphate from wastewater treatment plant (WWTP) are becoming more stringent and thus the alternative technologies are sought to enhance the P removal efficiency. In this study, Mg-Fe-Cl based layered double hydroxide (LDH) compounds were synthesized and used for phosphate removal. Implementing LDH as a tertiary treatment process for the removal and recovery of phosphate is proposed. Results show that LDH dosage of 2 g/l can reduce phosphate concentration down to 0.1 mg/l from an initial value of 10 mg/l at an equilibrium contact time of 2 and 3 h, respectively. The adsorption kinetics of phosphate onto Mg-Fe-Cl LDH is well governed by the pseudo-second-order kinetic model, and adsorption data fit well to the Langmuir and Freundlich isotherms. The study on pH effect of adsorbate solution suggested that pH range between 3–7.5 is suitable for unaffected phosphate removal. The repeated use of this LDH by both batch and fixed bed column experiment showed that total phosphate reduction was about 95% and desorption percentage was about 91% through six cycles of adsorption-desorption processes. It is likely that this LDH compounds can be applied to remove and recover phosphate from secondary effluent of domestic wastewater treatment plant and thereby, to meet future stringent discharge regulations.

Red mud, an aluminum industry large-scale waste, was used as a precursor to prepare sodium ferrate(VI) and sodium ferrite following different reaction pathways. Ferrous oxalate extracted from red mud has been used as an intermediate for the preparation of these compounds. The conversion rate to sodium ferrate(VI) from ferrous oxalate was as high as 64% in sodium hydroxide solution with sodium hypochlorite. Furthermore, sodium ferrite was formed after performing the solid–solid reaction at 600 °C using a 1:1 weight ratio of iron oxide (prepared via the ferrous oxalate extraction route from red mud) and sodium peroxide. In contrast, sodium iron silicon oxides were formed when red mud was reacted directly, following similar experimental procedures. These results present an interesting alternative to convert an environmentally unfriendly waste to new value-added products. It is envisaged that sodium ferrate(VI) might be of great interest in terms of wastewater treatment, whereas sodium ferrite and NawFexSiyOz might be of interest in the development of new materials for energy storage.

The work presented in this paper identified whether ferrate(VI) can be used as an alternative to the existing FeCl3 in drinking water treatment plant at Lake Constance Water Supply of Germany. The performance of ferrate(VI) was tested in a pilot plant, which includes micro-screening, pre-ozonation, coagulation, and rapid filtration processes. With a ferrate(VI) dose of 0.1 mg/L and without pH neutralization, the average particle removal percentage (in terms of particle counting) after filtration was 93% for raw water and 97% for ozonized water, which is satisfied to the treated water quality demand for particle removal. In comparison with using ozonation and FeCl3 coagulation, ferrate(VI) can remove 10% metformin, benzotiozole, and acesulfam from raw water but FeCl3 with ozonation cannot. Moreover, ferrate(VI) treated water did not generate bromate but ozonated water did (~11 μg/L). Finally, ferrate(VI) can effectively replace both ferric chloride and hydrogen peroxide in terms of achieving the required treatment performance and minimizing residual ozone, and no interaction between genotoxic effects and ferrate(VI) treatment was observed. This adds promising benefit of using ferrate(VI) for the given water quality and operating conditions in drinking water treatment.

The aim of this study was to investigate the overall performance of different types of recycled glass media with the optimized coagulation conditions for drinking water treatment. Tests were performed using a laboratory-based filtration unit, with dual filter media configurations and synthetic raw water. The glass media showed comparable performance for both filtration and backwashing and avoided the breakthrough of particles in the effluent. Moreover, the promising performance of the glass media was a slow head loss development which should grant longer filtration runs, less backwashing requirement and thus possible clean water and energy savings. Finally, the optimized combination of filtration media and coagulation operations can lead to the best filtration performance.

This paper investigates the degradation of acetaminophen (AAP) in aqueous solutions by ferrate (VI), aiming to propose the kinetics, pathways and the oxidation products' formation in the AAP degradation. A series of jar tests were undertaken over ferrate (VI) dosages (molar ratios of ferrate (VI):AAP, 5:1 to 25:1) and pH values (4-11). The effects of co-existing ions (0.2-5 mM) and humic acid (10-50 mg l(-1)) on the AAP removal were investigated. Ferrate (VI) can remove 99.6% AAP (from 1000 μg l(-1)) in 60 min under study conditions when majority of the AAP reduction occurred in the first 5 min. The treatment performance depended on the ferrate(VI) dosage, pH and the type and strength of co-existing ions and humic acid. Raising ferrate (VI) dosage with optimal pH 7 improved the AAP degradation. In the presence of humic acid, the AAP degradation by ferrate (VI) was promoted in a short period (<30 min) but then inhibited with increasing in humic acid contents. The presence of Al(3+), CO3(2-) and PO4(3-) ions declined but the existence of K(+), Na(+), Mg(2+) and Ca(2+) ions can improve the AAP removal. The catalytic function of Al(3+) on the decomposition of ferrate (VI) in aqueous solution was found. The kinetics of the reaction between ferrate (VI) and AAP was pseudo first-order for ferrete (VI) and pseudo second-order for AAP. The pseudo rate constant of ferrate (VI) with AAP was 1.4 × 10(-5) L(2) mg(-2) min(-1). Three oxidation products (OPs) were identified and the AAP degradation pathways were proposed.

This study investigated the ferrate(VI) performance in the removal of pharmaceuticals spiked in the secondary effluent taken from a wastewater treatment plant (WWTP). In the raw secondary effluent samples, seven of 12 target pharmaceuticals were detected with a maximum concentration of 500.0 ± 28.3 ng/L for ibuprofen. 70% of carbamazepine could be reduced in the raw effluent samples by ferrate(VI) when the dose exceeded 4 mg/L. In the modified effluent samples spiked with detected target pharmaceuticals, approximately 40% of naproxen was removed, whereas other target compounds were removed less than 30%. Raising the ferrate(VI) dose improved the removal of pharmaceuticals to some extent, while acidic conditions were more preferable for drugs’ reduction. The study demonstrated that ferrate(VI) can efficiently remove pharmaceuticals containing electron-rich moieties (ERMs), and the coagulation of iron(III) colloids resulted from the reduction of Fe(VI) also influenced the treatment performance.
