Extraction With Fine Particles From Washing Thickeners

Jan 01, 2016 The separation of solids from liquids is usually achieved by gravity sedimentation in thickeners. For fine particles this is a slow process. In general, 75–80 % of the water can be separated and removed by thickeners. For further water removal, filters are used where in excess of 90% of the water can be removed

  • Soil Washing

    Soil Washing

    Jan 29, 2013 Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts
