Mechanical dewatering means mechanical removal of liquids from a slurry to obtain the solids in a suitable form and/or recovery of a valueable liquid for: • Further processing • Transportation • Agglomeration • Disposal • Recovery of valuable liquids Gravimetric Dewatering When the particles in a slurry are too coarse for the capillary forces to “trap” the water, the use of gravity is enough to remove the water and give at least transportable solids. Spiral Dewaterer Spiral dewaterer for coarse solids (not deslimed). • Feed 1% solids by w. • 10 – 1 000 m3/h (44-44 000 USGPM) • Remaining moisture approx. 30% h2O • Large sedimentation-pool • Oil scimmer as option Sand spiral classifier (sand screw) This is a simpler version of the Spiral dewaterer mainly used for natural sand. These sands are normally classified (particles below 10-50 micron are removed) meaning that the sedimentation pool is very limited compared to the Spiral Dewater...
