DEME’s environmental companies are specialized in the treatment of sediment and sludge and recycling techniques, which have been developed by our Research & Development over decades. Some of these technologies, such as Soft Soil Improvement®, have been specifically developed for in-situ treatment, while others are used on a daily basis in our fully certified sludge processing centres.
Our sediment treatment techniques include:
Natural dewatering in lagoon fields
Mechanical dewatering (chamber filter compression, membrane compression, sieve belt presses)
In-situ consolidation via horizontal or vertical drains
Soft Soil Improvement®
Consolidation via horizontal or vertical drains
Sand/sludge separation via hydrocyclonage or sand separation techniques
