Project No.: ELKH-PoC-2023-8 project - Development of a Water Purification Technology System Using Bioadsorbents

10.11.2025

In the frame of the project, the Micropollutants and Water Treatment Technologies Research Group of the HUN-REN Research Centre for Astronomy and Earth Sciences developed an innovative, eco-friendly water treatment technology designed for testing low-cost adsorbents produced from green waste. Two modular, mobile pilot units were constructed for the removal of organic micropollutants such as pharmaceutical residues, pesticides, and volatile industrial contaminants.

The technology includes a Modular Filter System (MFS) with a capacity of 1 m3/day, consisting of three filter columns connectable in parallel or series, and a twin-tower Technology Demonstrator (TD) with a 10–20 m3/day capacity. Both systems are equipped with built-in electronics, and conductivity and pressure sensors. Laboratory and semi-industrial experiments confirmed the high removal efficiency of the technology. The intellectual property protection of the technology has also been initiated.

The project was implemented in close cooperation with several research and industrial partners, including the University of Pannonia (Circular Economy University Center and Soós Ernő Water Technology Research and Development Center in Nagykanizsa; Catalytic Technology Development Methodological Center in Veszprém). Further collaborations were established with HUN-REN institutes (KOKI, ATK, Bay Zoltán Research Institute). The systems are being tested and applied within a Hungarian–Slovak INTERREG project in partnership with DMRV Zrt., while high-ranked Portuguese universities (Porto and Aveiro) contribute to the technology’s further utilization. The new system and operation methods demonstrate high industrial potential. Commercial exploitation is underway in cooperation with our industrial partners.
