Cyclone performance on removing fibrous particles generated from terry-towels and cotton clothes

Experimental Approach to an Efficient and Versatile Water Filtration Vacuum Cleaner

“…There are two main types of filtering methods, namely, dry and wet filtering. Filtering is carried out in the dry type either by trapping the dust using a paper (usually disposable) filter or a reusable fabric filter, or by accelerating the air in cyclones where the dust particles are separated by centrifugal force . In water filtering, the air stream is initially sprayed by water to wet the dust before it is passed through a number of water‐filled containers to capture the dust and dirt particles.…”

Evaluation of concentration measurement techniques of colloidal nanoparticles for microfiltration and ultrafiltration applications: Inductively coupled plasma-mass spectrometry, nanoparticle tracking analysis and electrospray-scanning mobility particle sizer

“…As the world spurs the development of nanotechnologies, enormous benefits from nanomaterials are discovered but new harzards from nanosized materials may be created and then expose human and environment to health risks [11][12][13][14]. Therefore, efforts are needed to remove the nanomaterial contaminants emitted and discharged from different sources [15][16][17][18]. For example, researchers have been investigating the release of commercial engineered nanoparticles into various aqueous environments, e.g., groundwater, surface water and synthetic freshwater.…”

Prediction of the maximum-efficiency inlet velocity in cyclones

“…Investigations [1][2][3] on pressure drop have shown that increasing the inlet velocity led to an increase in pressure drop. Many experiments [1,[4][5][6][7][8][9] have determined a critical inlet velocity with respect to the separation efficiency. When the inlet velocity is smaller than the critical value, separation efficiency increases with the increase in inlet velocity; when the inlet velocity exceeds the critical value, the efficiency decreases with the increase in inlet velocity.…”
