An analysis on energy demands in airborne particulate matter filtration using hollow-fiber membranes
Bulejko, Pavel (Elsevier, 2021-05-12)This work analyzes energy requirements for drawing the air through a hollow-fiber membrane (HFM) during air filtration. Polypropylene HFMs varying in inner fiber diameter (230 and ) were used to separate the ASHRAE A2 fine ... -
An Assessment on Average Pressure Drop and Dust-Holding Capacity of Hollow-Fiber Membranes in Air Filtration
Bulejko, Pavel; Krištof, Ondřej; Dohnal, Miroslav (MDPI, 2021-06-24)In this work, we tried to analyze dust loading behavior of polypropylene hollow fiber membranes using average pressure drop models. Hollow fiber membranes varying in fiber diameter were loaded with a standardized test dust ... -
Experimental Study on Spray Breakup in Turbulent Atomization Using a Spiral Nozzle
Krištof, Ondřej; Bulejko, Pavel; Svěrák, Tomáš (MDPI, 2019-12-03)Spiral nozzles are widely used in wet scrubbers to form an appropriate spray pattern to capture the polluting gas/particulate matterwith the highest possible efficiency. Despite this fact, and a fact that it is a nozzle ... -
Numerical Comparison of Prediction Models for Aerosol Filtration Efficiency Applied on a Hollow-Fiber Membrane Pore Structure
Bulejko, Pavel (MDPI, 2018-06-19)Hollow-fiber membranes (HFMs) have widely been applied to many liquid treatment applications such as wastewater treatment, membrane contactors/bioreactors, membrane distillation etc. Despite the fact that HFMs are widely ... -
Potential use of blast furnace slag for filtration membranes preparation: A pilot study
Bílek, Vlastimil; Bulejko, Pavel; Kejík, Pavel; Hajzler, Jan; Másilko, Jiří; Bednárek, Jan; Tkacz, Jakub; Kalina, Lukáš (IOP Publishing, 2018-07-12)This paper investigates the possibilities of the use of sodium hydroxide activated blast furnace slag for preparation of filtration barriers. The motivation for this research is searching for cheaper and more eco-friendly ...
