Aqueous Iron(IV)-Oxo Complex: An Emerging Powerful Reactive Oxidant Formed by Iron(II)-Based Advanced Oxidation Processes for Oxidative Water Treatment

Zhen Wang et al.

Summary: High-valent iron(IV)-oxo complexes play a significant role as reactive intermediates in various chemical and biological systems. Among them, the aqueous iron(IV)-oxo complex ((FeaqO2+)-O-IV) is the simplest but also the most powerful ferryl ion species, showing high reactivity and selectivity in oxidizing water treatment. This review provides a comprehensive understanding of the chemical properties, oxidation mechanisms, and kinetics of (FeaqO2+)-O-IV, with comparisons to other free radicals. Additionally, the potential role of (FeaqO2+)-O-IV in Fe-aq(2+)-based advanced oxidation processes (AOPs) is discussed, challenging the conventional view that free radicals dominate these AOPs.

Dissolved organic carbon removal and CX3R-type byproduct formation during the peroxymonosulfate pre-oxidation followed by coagulation

Tiantian Chen et al.

Summary: Hydroxyl radicals and sulfate radicals can be generated when ferric-based coagulants are coupled with the potential alternative pre-oxidant peroxymonosulfate (PMS). The study found that Fe2(SO4)3 was the most suitable coagulant in terms of DOC removal and avoiding the formation of toxic CX3R-type byproducts, compared to FeCl3 and AlCl3. The presence of FeCl3 and AlCl3 during PPFC led to the formation of significant toxic CX3R-type byproducts, which decreased with longer pre-oxidation duration and increased PMS concentration.

Degradation of Organic Contaminants in the Fe(II)/Peroxymonosulfate Process under Acidic Conditions: The Overlooked Rapid Oxidation Stage

Hongyu Dong et al.

Summary: This study investigated the kinetics and mechanisms of organic contaminants degradation in the iron(II)-activated peroxymonosulfate process under acidic conditions. It found that organic contaminants were rapidly oxidized in the rapid oxidation stage with different oxidants contributing to degradation, while in the slow oxidation stage, degradation was slower and less oxidants were generated.

Removal of natural organic matter from source water: Review on coagulants, dual coagulation, alternative coagulants, and mechanisms

H. N. P. Dayarathne et al.

Summary: Natural organic matter (NOM) can significantly impact drinking water quality, causing taste, odour, and colour problems. Removing NOM is challenging as it can lead to the formation of disinfection by-products which are harmful to human health. Various technologies have been used to remove NOM, with coagulants being the most common method.

The role of interactions between extracellular organic matter and humic substances on coagulation-ultrafiltration process

Huikai Liang et al.

Summary: The study found that in a mixed system of cyanobacterium M. aeruginosa and humic acid (HA), the presence of HA can improve the removal efficiency of extracellular organic matter (EOM) and reduce membrane fouling. The interaction between HA and EOM strengthens charge neutralization and reduces chemical bonds, positively impacting the coagulation process.

Bromide-intrusion into Chlorella sp. and Microcystis aeruginosa growing environments: Its impacts on algal growth and the formation potential of algal-derived DBPs upon chlorination

Lap-Cuong Hua et al.

Summary: This study investigated the impact of bromide intrusion on two freshwater algae species. The results showed that the algae were well-adapted to bromide intrusion and exhibited no significant effect on growth and precursor characteristics. However, bromide intrusion significantly affected the production of brominated disinfection byproducts during chlorination processes.

Increasing Bromine in Intracellular Organic Matter of Freshwater Algae Growing in Bromide-Elevated Environments and Its Impacts on Characteristics of DBP Precursors

Lap-Cuong Hua et al.

Summary: This study demonstrates that freshwater algae can accumulate bromine and contribute to the formation of brominated disinfection byproducts during chlorination. Elevated bromide levels in source water increase bromine accumulation inside algae cells, leading to a significant impact on the toxic potency of chlorinated water. These findings provide insights into the origins of natural organic bromine in freshwater environments and the potential influence of algae and bromide elevation on water quality after chlorination.
