In the plant's control room, Penrice's workers watch crystals form on the outside of a vacuum-drum filter.
Filtration is carried out in gravity filters (screens, dewatering bins), in centrifugal filters (screen centrifuges), in vacuum filters (drum cell filters, disk filters), or in pressure filters (filter presses).
And its enormous steering wheel guided the wheels straight and true, although its vacuum-assisted drum brakes provided somewhat uncertain stopping power.
Later this month, he'll release an EP called Forget It for New York's underground techno mainstay The Bunker, and on it he's stuffed four relentless tracks of spiraling vocal snippets, vacuum-sealed drums, and crimped acid earworms.

Filtration data from laboratory and pilot plant scale were used to compare the performance of rotary drum vacuum filters (RDVF), batch filtering centrifuges and decanting centrifuges.
Since a good deal of land area is needed for drying beds, this method of dewatering is commonly used in rural or suburban towns rather than in densely populated cities. Alternatives to sludge-drying beds include the rotary drum vacuum filter, the centrifuge, and the belt filter press.
Without admitting wrongdoing, Whittier Drum & Vacuum Co. agreed under a stipulated judgment to pay $25,000 in civil penalties and $8,279 for the county's legal and investigative costs.
