Mechanical Dewatering: Dredging & Dewatering

Mechanical Dewatering

There are many options for mechanical dewatering systems on the global market, but only a few players have it right.  Triflo International is one of these companies and its roots are based firmly in the oil drilling business.  They have used their experience from dewatering drilling mud and applied it to dewatering dredged slurries from portable hydraulic dredges.

Before exploring the option of mechanical dewatering it is important to understand that a dewatering system can cost as much as the dredge it is receiving material from.  If the project is high dollar or high volume then this cost can be justified, but if there is very little material then a standard spoils site or geotextile tubes are a much more economical option.  Areas like ports, municipal canals in city centers, lakes with no discharge sites and marinas on packed coastlines are often great candidates for mechanical dewatering.

Here is a list of the separation systems that Triflo manufactures for separating slurries from a dredging operation:

  • ES series- separation down to 10 micron.
    • Capacities- 300 Gpm and 500 gpm.
    • These systems are used mostly in industrial pond dredging with the small, remote controlled dredges.
    • Can be trailer mounted or skid mounted.
  • DSS series-Separation down to 25 micron.
    • Capacities – 1000 gpm and 2000 gpm.
    • Higher capacity is attained by using multiple systems.
    • All systems are portable and highway legal without permits.

Sizing of the system is dictated by the output capabilities of the dredge.   It is important to note that these systems can be stacked in tandem and large capacity dredges can be accommodated.

Triflo operates a sample testing facility which gives us, and the client the information and predictions required for bidding a project.  Representative 5-gallon samples are required to perform the testing procedures.
