Case Histories

Griffin Industries rendering plant

Application: Dredging settled rendering sludge from discharge ponds.

Griffin Industries uses its Crisafulli FLUMP on a rotating basis to dredge and manage settled wastes at multiple sites. The 4” Severe Duty FLUMP has foam-filled modular polyethylene pontoons and coal tar epoxy coating throughout. The FLUMP dredge is operated manually from an on-shore control panel with a hard-wire remote control capable of giving commands from up to 400 feet away. The Crisafulli FLUMP is transported from site-to-site on an as-needed basis.

Pigment Plant

February 1996. Mearl Corporation owns and operates an Automated FLUMP™ System manufactured by SRS Crisafulli. Operation is from shore based control panel. The FLUMP was used to remove mica from a settling pond at a pigment plant. Material is 8 to 10 micron size and contains small amounts of titanium dioxide. pH level in containment is 10 due to some dissolved salts. Sludge is pumped @ 19.5% solids with a specific gravity of 1.08 and a viscosity of 750 cp. This system was manufactured from A36 carbon and abrasion resistant steel. Wetted parts were coated with coal tar epoxy coating to resist corrosion due to nature of liquid in containment. Hardwired remote control from the shore to dredge was used. Automated features are automatic reversing function, lateral move and additional inputs for level control of containment. Traverse speed and cutterhead speed were made adjustable to reduce re-suspension of solids as conditions demanded.

Four Flumps to Canada

August 2007. A major Canadian mining company purchased four Crisafulli FLUMP dredges to replace their pond cleaning methods (manually hosing solids to a sump pump) and reported that the operation of the FLUMPs exceeded expectations; the FLUMPs worked very well and removed lots of solids; the FLUMPs performed much faster and more easily than the prior method.
