WebbSlug Flow is a typical two-phase flow where a wave is picked up periodically by the rapidly moving gas to form a frothy slug, which passes along the pipe at a greater velocity than the average liquid velocity. In this type of flow, slugs can cause severe and, in some cases, dangerous vibrations in piping systems because of the impact of the ...

Webb17 jan. 2013 · Upflow anaerobic sludge blanket, or UASB, is a form of anaerobic (oxygen-free) digester used in wastewater treatment. It is a methane-producing digester which uses an anaerobic process and forming a blanket of granular sludge and is processed by anaerobic microorganism. UASB was developed in 1970s by Letinga in the Netherlands. Webb15 mars 2013 · The density of slurry can be calculated from the following equation: ρ m = 100 / (C w /ρ s) + [ (100 - C w) / ρ L ] where: ρ m =density of slurry mixture, kg/m 3 C w = solids concentration by weight, % ρ s = density of solid in mixture, kg/m 3 ρ L = density of liquid in mixture, kg/m 3
