Deltares: Faster Reuse of Dredged Sediment by Using Worms

Oligochaete worms can substantially speed up the reuse of both dredged sediment and contaminated mine tailings, Deltares said in their latest release

Researchers from Deltares, with the support from the University of Alberta, Queen Mary University of London and NAIT (polytechnic and applied research institute) have determined this in laboratory tests.

According to their statement, in the Netherlands, this nature-based technology is promising for the circular reuse of dredged material, while in Canada the mining industry is interested particularly for mine sites closure.

The fact that the small worms accelerate the dewatering of sediment with their bustle and appetite was already known and tested in for example water treatment plants.

But now the Dutch, Canadians and British have designed the conditions under which these worms will continue to live in (oil sands) mine tailings.

“At this moment we still talk about laboratory tests, but the first results have positioned this technology as a promising alternative to traditional sediment management, both technically and financially,” said Deltares.

This technology reduces the storage volume, speeds up dewatering, enhances strength development, and reduces the use of chemical water treatment.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
