Plenary Presentation: Subjective tales on the periodic table with a focus on oxidative water treatment
Over the past three decades, oxidative water treatment has been substantially advanced through kinetic and mechanistic studies. These developments have deepened the understanding of micropollutant abatement, the formation of transformation products, and reactions with matrix components such as dissolved organic matter (DOM), bromide, and iodide, which may further lead to disinfection by-products (DBPs). This plenary talk will illustrate key aspects of oxidative water treatment through selected mini-reviews organized around elements and compounds across the periodic table that have been investigated over the course of a long-term research career. Topics will cover the kinetics and mechanisms of oxidation processes, as well as the formation of transformation products and disinfection by-products. To create an interactive format, the specific topics will be selected arbitrarily by raffle with audience participation.

Plenary Presentation: Exposome-scale Discovery of Hidden N-Dimethylamine Precursors and Halogenated Disinfection By-products from Nontargeted Analysis
High-resolution mass spectrometry and data-driven analytical approaches have substantially advanced the characterization of previously unrecognized disinfection by-product precursors and halogenated DBPs in water systems. These developments have deepened the understanding of complex precursor–product relationships, especially for NDMA precursors and chlorinated, brominated, and iodinated organic compounds formed during water treatment. This plenary talk will illustrate key strategies for nontargeted DBPs discovery through selected examples integrating high-resolution mass spectrometry, bioinformatic tools, and machine learning-assisted workflows. Topics will cover the methodological design and applications of NitraPreX, HalogenFinder, and IodoFinder, with emphasis on their use in source water, finished water, and laboratory chlorination systems to support more comprehensive identification and risk-oriented assessment of emerging DBPs.

Keynote Presentation: Hydrogen peroxide and free available chlorine activation and quenching at non-ferrous/ic and non-cuprous/ic metal(loid) oxide surfaces: Potential applications for water treatment and beyond
Recent studies have shown that metal(loid) oxide surfaces can markedly regulate the activation and quenching of common oxidants in water treatment. Building on this emerging interfacial chemistry, this keynote will examine how non-ferrous/ic and non-cuprous/ic oxides, including zirconium, cerium, titanium, silicon, and aluminum oxides, mediate the reactions of hydrogen peroxide and free available chlorine. Topics will cover oxidant decomposition kinetics, reactive oxygen and chlorine species formation, and mechanistic identification using scavengers and probe compounds. Applications in organic contaminant degradation, microbial inactivation, residual oxidant removal, and point-of-use precoat filtration will also be discussed.

Keynote Presentation: Deciphering the unintentional consequences on dissemination of horizontal genetic elements due to water reuse in agriculture
Agricultural water reuse is increasingly adopted to alleviate water scarcity, yet its unintended microbiological impacts remain insufficiently understood. This keynote will examine how reclaimed wastewater may influence the dissemination of horizontal genetic elements in soil environments, with emphasis on natural transformation. It will examine how treated effluents from different membrane bioreactor and disinfection processes interact with sunlight exposure, extracellular DNA, chemical stressors, and agricultural soils. Topics will cover reporter-based transformation assays using Acinetobacter baylyi ADP1, crop-associated soil microcosms, and metagenomic analyses to evaluate transformation events, antibiotic resistance genes, microbial community responses, and broader microbial safety implications of wastewater reuse.

Keynote Presentation: Novel UV and UV-AOP Processes Research and Development for Water Treatment and Reuse
Emerging contaminants are posing increasing challenges to water treatment and reuse, as conventional processes often show limited capacity for their effective control. This keynote will examine the development of novel UV and UV-based advanced oxidation processes as alternative strategies for addressing pharmaceuticals and personal care products, hormones, PFAS, antibiotic-resistant bacteria and genes, and microplastics in aquatic environments. Topics will cover the principles and optimization of UV-driven treatment systems, with emphasis on organic contaminant degradation and microbial contaminant inactivation. Applications related to safe drinking water production, wastewater treatment, and water reuse will also be discussed.
