Perfluorocarbons in water

The research of micropollutants including PFC (perfluorocarbons, perfluorated compounds – see the frame) in drinking water and their prospective influence on human health is nowadays one of the most significant research topics in the field of drinking water. Nevertheless, the practical applications in the drinking water treatment plant operations falls behind this basic research, although […]

Recently, the presence of plastics in water environment has gained considerable attention. Not only plastic litter that is visible to the naked eye, but also smaller debris – recognized as microplastics – are of a great interest. Microplastics (MPs; plastic particles smaller than 5 mm) have been detected in different water bodies, i.e. oceans, seas […]

Fluid mechanics

With the transport of bulk materials in the form of a two-phase suspension (liquid-solid phase) we can meet in a number of industries - chemical, food, mining, energy and many others. In addition to closed pipe systems, which are usually hidden for ordinary citizens in industrial agglomerations, the two-phase flow is part of river systems […]
