High-Speed Material Separation and Dewatering

Brennan’s experience in both passive dewatering systems and active (mechanical) dewatering systems will provide the flexibility required in debris separation, sediment consolidation and water treatment challenges.  There are several choices and combinations to consider as there is no one-best option for every project.  What worked on one project, may be disastrous on another.  Because of this we take a much different approach to maximize dredge production, material separation efficiency, and the dewatering process effectiveness.  As a result, we can offer more value and cost savings to our clients.

Once the sediment has been separated, or if it is decided that no separation process is required, then we will either self-perform the final dewatering stage, or team with an industry leader who specializes in a certain process.  Typically Brennan will self-perform disposal and dewatering in Contained Discharge Facilities (CDFs) or temporary holding facilities.  In the case of mechanical processing we will team with the best companies in the industry for plate and frame and belt press processing.  We also will team with companies that are the best in the industry at dewatering geotextile tubes if a passive system is chosen.  These strategic teaming arrangements give us the flexibility to implement the BEST system for each challenge without sacrificing production.
