The Chair of Dispersed Systems Engineering, which is part of the Faculty of Chemical and Process Engineering at Warsaw University of Technology, was established more than 10 years ago on the initiative of Prof. Leon Gradoń, as a result of the merger of two departments: Department of Process Apparatus and Department of Basic Processes and Environmental Protection. Research topics currently carried out in the Department focus on the engineering of dispersed systems, which include a variety of colloidal systems (with micro- and nanometric fineness), including aerosols, suspensions, emulsions. In the Department of Integrated Process Engineering, two main research streams can be distinguished:

• separation of dispersed systems - here we mainly deal with such processes as filtration of aerosols, liquid suspensions and separation of emulsions (water, fuels), using filter structures and membranes;
• description of processes running in the living organism, especially processes related to fluid flows (air, blood, bronchial mucus, lung surfactant) and mass exchange (e.g., deposition of inhaled aerosol particles in the respiratory system, drug distribution).

In terms of the separation stream (1), research work focuses on the description of the basic mechanisms responsible for the process of particle filtration and the design, manufacture and testing of nonwoven filter layers, as well as membrane structures, of wide application (including food, pharmaceutical, environmental protection industries).

In the case of the "biomedical" stream (2), research work includes, among other things, the description of aerosol formation processes in inhalers of various designs (powder, nebulizers), the design of devices to ensure adequate dosage levels of therapeutic aerosol, research on the movement and deposition (deposition) of aerosol particles in the human respiratory system, and finally - on the physicochemical interactions of aerosol particles (including drugs or inhaled pollutants) with the model surface of the respiratory system. The results of these studies are of greatest importance to the pharmaceutical industry.

Both research streams use chemical engineering tools based on in silico process modeling and in vitro experiments.

The Chair is currently headed by Prof. Tomasz Sosnowski, PhD.
