Granular bed filtration of a liquid aerosol
WebA down-flow granular medium bed filter (10) is provided with at least one splash plate (20) for dissipating the force of influent liquid, the plate being mounted so as to be rotatable by lifting means (24,26) from a position parallel to the surface of the filter bed (14) to a position perpendicular to the bed surface when the liquid above the ... WebFiltration Removal of particles (solids) from a suspension (two-phase system containing particles and liquid) by passage of the suspension through a porous medium. In granular filtration, the porous medium is a bed of granular material. Filtration rate Key process variable; the superficial water velocity
