In comparison with filtration, thickening offers the advantage of low operation
Components of the solidliquid separation process Cake filters can be further divided into pressure, vacuum, centrifugal and gravity operations. Post-treatment processes involve making improvements to the quality of the solid or liquid products. . Filter thickeners or crossflow filters, e.g., delayed cake, dynamic or high
Pulp is fed to the center of the drum at the drive end, and thickened pulp is Filtrate is collected in a filtrate tray that drains by gravity to a filtrate tank. The process is controlled by the height of the discharge weir, filtrate level in the tray i.e., Can accommodate large swings if feed flow - great for broke thickening; Can be
Its enhanced design improves process performance while minimizing operating costs. ALDEC G3 decanters for centrifugal separation with high capacity and high rotary drum filters for very gentle, small to medium capacity sludge thickening obtain class A or B sludge quality suitable for reuse as compost or fertilizer.
drum thickener for sludge treatment higher speed than the micro flocs of conventional thickeners. This in devices ensures a high clarification efficiency and a good clarified flow quality. gravity separator process water grit MoReSa 4.0.
Physical solid-liquid separation processes rely on the density, size, or shape of the Settling by gravity is effective in waste water with less than one percent total solids. the liquids drain through the screen and the solids fall off the lower end. However, centrifuge separators function best with liquid slurries <4% solids
