Applicability Limitations

This treatment is limited to dewatering sludges (including metal-bearing sludges), separating oils from water, and clarification of viscous gums and resins. Centrifuges are generally better suited than vacuum filters for dewatering sticky or gelatinous sludges. Disc-type centrifuges (Figure 11.15.2) can be used to separate three component mixtures (e.g. oil, water, and solids). Centrifuges often cannot be used for clarification since they may fail to remove less dense solids and those small enough to remain in suspension. Recovery and removal efficiencies may be improved if paper or cloth filters are used.
