• Dewatering drum is mounted on a roll-off frame making it easily transported.
• Drum is supported by greaseable roller bearings.
• Drum rotates with roller chain.
• Gear box turns by variable speed motor.
• Low energy required: ¼ / ½ horsepower motor.
• There are two doors on the back of the drum; one for inspection while filling, the other hinged door for unloading the dry material. There is an additional manhole port on the front for inspection as well.
• Three inch quick cam lock for loading liquid.
• Unit is lined with PVC filter tiles.
• Tiles are interlocking and replaceable.
• Tiles are self cleaning.
• Water is constantly being drained while the drum is being filled.
• Liquid can be added to drum several times before being rotated.
• Once full, or ready to be rotated, the inspection door must be secured before rotating unit.
• The ideal speed seems to be one revolution every 2 hours.
• The drum always rotates toward the gearbox.
• After approximately 5 revolutions the unit is ready to be loaded on a roll-off truck to be emptied.
• Drum must be rotated until dry sludge is parallel with the door opening.
• Once the material is centered in the bottom of the drum it must be secured for transport.
• Securing is achieved by tightening the ratchet with the straps hooked on the frame.
• To unload material the wing nuts that secure the door must be loosened (suggestion: loosening all but one wing nut while the drum is on the ground. This becomes more difficult as machine is higher up once positioned on truck).
• Once unit has been emptied it is ready to be rinsed out prior to the next fill.
• A normal rinse time would be 10 minutes with a garden hose and spray nozzle. (video)
• Unit works well with any liquid that will flocculate.
• Drum is made completely of stainless steel and PVC.
• Results are very predictable and consistent (no surprises).
