Rotomite : a small exclusive dredger : New technology for construction(No. 10 reservoir sludge dredging method)

1

ROTOMITE is a special purpose sludge dredger that equips strong CutterHead and high efficient pump, designed for one-man to easily operate dredging even heavily thick sediments of sludge.
Also, as a self-propulsion system, It is capable of dredging operation without cable or anchoring.

Applicable service of Exclusive Dredger for Sludge

2
  • waterway dredging
  • river maintenance
  • emergent pollutant removal
  • purification of polluted environment
  • removal of toxic substance or water grass on pond or lake
  • 점성수 removal
  • sand or pebble removal
  • removal or management of pollutant in sanitary landfill

It is a classificator that separates send sludge or mire, which are dredged by hydraulic driven rotating cutter on the small boat, to either sediment sludge or water through 1st water content reduction process equipment installed in grit chamber or construction storage yard(가설적치장).
Processing sand sediments or sludge using this classificator will raise the efficiency of dredger operating process and can dispose minimized sunken sludge that are made through 2nd and 3rd grit chambers where water is discharged by overflowing. The deposit soil that are dredged by the small boat can reduce the amount of waste when water content rate is reduced as its content of sludge is over 80%.
Sludge or sludge-type dredged soil which are of no use for aggregate can be processed only by removing water. The advantage of exclusive dredger for sludge is that it is a part of construction method that can reduce huge amount of construction cost by removing existing process of construction that are operating from dredging through moving, dehydration, separation, load to disposal.

Benefits of exclusive dredger for sludge

  • The amount of waste can be reduced by minimizing water content rate of dredged soil.
  • Huge amount of budget for waste disposal can be reduced
