A research team from the Department of Tourism and Recreation at the Faculty of Geographical and Geological Sciences, Adam Mickiewicz University (UAM), has developed and patented a groundbreaking method for purifying lake water — a solution that could revolutionize recreational use of water bodies across Poland.
The technology was developed by Eng. Adam Młynarczyk, Prof. Zygmunt Młynarczyk, and Dr. Grzegorz Borkowski. Their innovative system involves creating designated swimming zones equipped with barriers that prevent pollutants and cyanobacteria — a major health risk during the summer season — from entering the bathing area.
Water is drawn through filters in the lakebed or underlying geological layers, then passes through pumps for aeration, ozonation or ultraviolet treatment before being returned under pressure via diffusers that further oxygenate and warm it, lead researcher Grzegorz Borkowski told the university website.
Once initially filtered, the water may be further processed through aeration, ozonation, and UV radiation. After treatment, it is returned under pressure to the bathing area through a system of diffusers, which simultaneously aerate and warm the water through contact with atmospheric air.
To enhance the recreational experience, the bathing zones can also include water features that double as purification and heating aids.
This purification system will operate continuously throughout the bathing season. Once the season ends, the barrier will be removed, allowing the treated water to naturally mix back into the lake.
The technology was presented in early July at the Ministry of Sport and Tourism. State Secretary Piotr Borys and ministry officials discussed nationwide deployment options.
