Lecture “Hidden Danger: Presence of Arsenic in Drinking Water” gave an overview of the importance of ensuring the chemical quality of drinking water. Special focus was given to the metalloid arsenic, its prevalence in the environment, forms of occurrence, and mechanisms of entry into drinking water resources, as well as health problems it can cause with chronic exposure. The role and importance of the NanoCompAs project in implementing a modern technological approach to drinking water treatment was highlighted.
Prof. dr Božo Dalmacija: Resursi vode za piće u RS i WBC 
Through the lecture on the topic “Drinking water resources in RS and WBC”, workshop participants were informed about the increasing challenges regarding the availability and quality of drinking water resources, as well as the existence of initiatives for the preservation of water resources through regional cooperation, infrastructure modernization, and raising awareness about the quality and availability of water resources. Special attention was given to the drinking water resources and the economy in Serbia.
Vanr. prof. dr Malcolm Watson: Određivanje sadržaja arsena u vodi za pićeVanr. prof. dr Malcolm Watson: Pilot istraživanja uklanjanja arsena
Dr Watson’s first presentation focused on the contrasting analytical demands of routine As analysis for the protection of public health, and the more in depth speciation methods which can be used to explore the efficacy of arsenic removal technologies. His second presentation discussed the importance of pilot investigations in the field in the early planning phase of drinking water treatment plant construction.
Prof. dr Srđan Rončević: Najbolje dostupne tehnike za uklanjanje arsena iz vode za piće 
Best available techniques for arsenic removal from drinking water” provided an overview of the conventional techniques for arsenic removal. In addition to the principles on which the process is based, the advantages and disadvantages of each of the most commonly used techniques were explained in detail, including coagulation and flocculation, other precipitation processes, adsorption, ion exchange, membrane filtration, and others. The oxidation process has been addressed through examples of the application of different oxidizing agents.
Dr Jasmina Nikić: Savremena rešenja uklanjanja arsena iz vode 
Dr Nikić presented innovative solutions for arsenic removal during her talk at the NanoCompAs day. Special emphasis was placed on iron-based nanomaterials, and corresponding nanocomposites with advantages and limitations of these cutting-edge materials, particularly in overcoming challenges like scalability, environmental impact, and cost-effectiveness in arsenic removal. She introduced the NanoCompAs project, which aims to bridge existing gaps by optimizing the synthesis and scaling up the production of FMBO nanocomposites.
Dr Maja Vujić: Održivo upravljanje otpadnim tokovima koji sadrže arsen 
Dr. Maja Vujić discussed the waste flows generated during drinking water treatment, and the importance of implementing effective waste management practices to mitigate the environmental impacts associated with drinking water treatment residues. Dr Vujić highlighted how the NanoCompAs project aims to develop innovative water treatment materials with sustainable end-of-life solutions.
Dr Mirjana Vijatović Petrović: Ponovna upotreba utrošenih adsorbenata 
Dr Mirjana Vijatović Petrović presented an innovative methodology for the reuse of fully utilized materials by forming composite structures. A significant aspect of her presentation was the development of piezoelectric materials, which benefit from this integration through enhanced functional properties. This approach not only improves the performance of the resulting materials but also addresses sustainability concerns by minimizing waste generation.
