Summary: During harmful algal blooms (HABS), permanganate can be used as a preoxidant to improve drinking water quality by removing algal cells and degrading algal toxins. However, permanganate oxidation also alters the precursors of disinfection byproducts (DBPs) from intracellular algal organic matter (AOM), affecting DBP formation during disinfection. This study evaluated the impacts of permanganate preoxidation on DBP generation during chlorination and chloramination of AOM. The results showed that permanganate preoxidation increased the formation of certain DBPs and decreased others, indicating a complex interaction between permanganate and AOM.

Summary: UV/chlorine process is effective in eliminating pathogens and refractory micro-pollutants in the reclamation of municipal secondary effluent. However, the high organic nitrogen content of effluent organic matter (EfOM) can lead to the formation of nitrogenous disinfection byproducts (N-DBPs) of health concern. This study tracked the molecular-level changes of hydrophobic (HPO) and transphilic (TPI) EfOM fractions during UV/chlorine treatment and observed the formation of diverse and intense N-DBPs. Toxicity bioassays showed that these N-DBPs can induce oxidative stress-induced DNA damage. The study highlights the importance of evaluating EfOM characteristics and transformation for the practical application of the UV/chlorine process.

Summary: Pre-ozonation can effectively reduce the formation of disinfection byproducts (DBPs) during subsequent chlorination by oxidizing electron-donating-moieties (EDMs) and UVA in natural organic matter, especially in high and medium molecular weight fractions. The study found that pre-ozonation inhibited the formation of representative DBPs, total organic chloride, and cytotoxicity, but may have promoted the formation of carbonyl-DBPs. Additionally, EDM abatement was found to better reflect the formation of total organic chlorine and cytotoxicity, indicating a complex relationship between EDM removal and the speciation of DBPs.

Summary: Disinfection is effective in eliminating pathogens in drinking water treatment, but the formation of disinfection byproducts (DBPs) can lead to serious health concerns. Previous research mainly focused on DBP formation during disinfection in water treatment plants, with little attention to their formation and transformation in the water distribution system (WDS). This paper provides a comprehensive review of DBP formation and transformation in the WDS, cataloging their occurrence worldwide and summarizing the primary factors influencing their formation, such as secondary chlorination, pipe materials, biofilm, deposits, and coexisting anions. The review also describes the mechanism of DBP formation and transformation in the WDS, highlighting the conversion of aromatic DBPs to aliphatic DBPs and examines the toxicity of drinking water in the WDS caused by DBP transformation.

Summary: This study investigates the impact of NaOCl oxidation-assisted PACl coagulation on algae removal, showing that higher NaOCl oxidant dose with PACl coagulation is more effective in destabilizing and removing Microcystis aeruginosa cells, but fails to reduce the DOC in the suspension. Strong free chlorine destroys MA cells by increasing HAL and FAL substances, with sufficient degradation of SMPL and APL substances. The changes in fluorescent organic matter fraction during chlorination dominantly affect coagulation performance in the oxidation-coagulation process for AOM removal.

Summary: This study investigated the effects of pre-chlorination on Microcystis aeruginosa-laden water in different growth phases and the formation of carbonaceous disinfection by-products. The results showed that chlorination at the exponential phase led to faster and stronger degradation of algal cells, resulting in more significant viability loss and the formation of disinfection by-products, especially trihalomethanes. Pre-chlorination played a key role in the in-situ formation of disinfection by-products, with precursors contributing differently at each growth phase.

Summary: This study investigated the effects of intensified NaOCl and ClO2 pre-oxidation on the removal of Microcystis aeruginosa (MA) and corresponding halogenated DBP precursors by PACl coagulation with different Al hydrates. The results showed that NaOCl pre-oxidation with PACl-W coagulation was more effective in reducing MA cell and algogenic organic matter (AOM), while ClO2 pre-oxidation with PACl-H coagulation outperformed in reducing various DOM substances and halogenated DBP precursors. Intensified NaOCl pre-oxidation was found to be an alternative method to minimize DBP precursors in oxidation-coagulation processes for cyanobacteria-laden water treatment, with results comparable to ClO2 oxidation combined with PACl coagulation.
