Using sunlight to clean water

Researchers at the University of Szeged are working on a nanotechnological water treatment device. Their innovation may provide clean water for millions worldwide in the future.

Researchers at the Department of Chemistry of the University of Szeged are contributing to water management and water treatment systems with their cutting-edge development work conducted in cooperation with the Applied Material Science Research Group of Amity University in India and Hungarian partners.

“We are designing a system that can be operated economically on a smaller scale, and which is effective both against the remnants of pharmaceutical and agrochemicals that cause problems in Hungary and the textile industry wastewater that are problematic in the partner country,” said Klára Hernádi, a lecturer at the university’s Department of Applied and Environmental Chemistry, in a statement published by the University of Szeged.

The family of highly efficient photocatalysts that operate with the energy of visible light and which can be produced using green technology contains bismuth oxohalides synthesised using plant templates. This new type of photocatalyst can utilise a significant proportion of sunlight, and therefore it is able to neutralise organic materials in the water, or perform biological disinfection on treated surfaces.

The 3-year project concluding on 30 November 2019, which has received HUF 55,572,250 in funding, tests the industrial applicability and the possibility of development into a product of the complex water treatment system they wish to develop.

Hungarian developments may solve the problem of pharmaceutical residues worldwide

The filtering of pharmaceutical derivatives from water is a problem for almost the entire world. That was part of the reason for the international interest elicited at the Budapest Water Summit by the results of a National Competitiveness and Excellence Programme (NVKP) project led by the Geographical Institute of the Hungarian Academy of Science’s Research Centre for Astronomy and Earth Sciences, which cover the complete set of associated problems.

Budapest Water Summit attracts tremendous interest

A great many people were interested in the Budapest Water Summit – the importance of the event is attested by the fact that over 2,300 people from 118 countries had applied to attend the event, and along with the over 30 ministerial delegations, leaders of international organisations and multilateral financing institutions, as well as water industry experts have also attended.
