DEWATERED & DYNAMICALLY HANDLED

Dredged materials have a long and successful record in the manufacture of structural strength concrete for the construction industry. But handling dredged materials through dredging of lakes, oceans, ponds, can be challenging due to variable nature of excavated material and and because material often needs to be decontaminated. 

Traditional washing equipment is robust in nature, but it lacks the efficiency needed to capture all saleable product in the process. Dredged materials can be challenging due to the variable nature of excavated material and because material often needs to be decontaminated.

CDE’s modular dredged sand washing solutions are fine-tuned specifically to address the individual characteristics of feed material and the desired final product specifications. Our advanced classification and dewatering technology increases the accuracy of separation and delivers a product with less moisture content than traditional methods, straight off the belts.

We deliver solutions for both contaminated and non-contaminated dredged material and our solutions can help to regulate the flow of material fed direct from the dredge pump, delivering a consistent flow, with no double handling or drying time required before you feed your plant.

We guarantee a full turnkey proven wet processing solution that will increase operating efficiency and reduce costs from processing recovered fines. It delivers big savings on maintenance and removes unnecessary health & safety risks. And it increases yields by minimizing the loss of quality fines from your dredged material producing a higher quality product.

Our system can also be combined with tertiary water treatment, can be commissioned on a barge reducing the need for jetties and eliminating the costs associated with them.

DREDGE SOLUTIONS

Our dredge solutions are designed to regulate the flow of material fed direct from the dredge pump, delivering a consistent flow, with no double handling or drying time required before you feed your plant. This includes a range of scrubbing, washing, classification, dewatering and purification equipment.

Our sophisticated screening system dewaters non-contaminated dredged material and removes particles down to 35 micron / 400 mesh. This results in up to 90% of water being removed from silt and grit so the need for solidifying with Portland cement or sawdust is eliminated and disposal costs are kept to a minimum.

Output products generated can be reused or sold for use in various applications such as top soil, pipe bedding, backfill or concrete sand for ready-mix.
