Envisan, in collaboration with the dredging department, designs specific equipment and techniques (both hydraulic and mechanical) to remove sediments from the sea or river bed as efficiently and environmentally friendly as possible. Contaminated sediments are dewatered and then treated by means of various techniques either on site or in our own cleaning centers before they are given a final destination. In most cases, the cleaned sediments can be reused in architectural applications. The most commonly used techniques for the adjunctive treatment of sediments are: Organic cleaning Physico-chemical cleaning Desanding by hydrocyclonage Immobilization / stabilization References Techniques General Disclaimer Privacy Policy Sitemap Contact Left Jan De Nul Group Sol & Val CPEM PSR Eraerts © Envisan I webmaster @ envisan.com
