Microplastics in drinking water

A unique research confirmed drinking water contains microplastics The researchers from the Institute of Hydrodynamics confirmed the presence of plastic particles in drinking water from the three water treatment plants (WTPs) in the Czech Republic. Microplastisc were present in all analyzed samples of both raw and treated drinking water. The results of this unique research are […]

Fluid mechanics is the branch of physics concerned with balance and movement of fluids and fluid systems under the influence of external and internal forces. The fundamental difference between the rigid body and the fluid is the mobility of the molecules. 


Rheology is the study of the flow and deformation of matter. Rheological characteristics of materials are given by the type of applied flow and their physicochemical properties.


Hydrology studies the principles of water movements over the Earth. The main aim of the hydrological research is to define an occurrence of water, its circulation, spatial distribution, physical and chemical properties, and it relation to biosphere. 


Drinking water treatment is a technological branch dealing with removal of undesirable impurities from water. The most employed method is a formation of suspension by the means of dosing and mixing coagulants and subsequent separation of formed suspension by sedimentation and/or filtration.
