WODCON XX: Study on Applying Hydrocyclone for Improving Loading Efficiency of TSHD

The hydrocyclone is equipment for solid-liquid mixture separation.

It can be used to both separate and concentrate dredged material. When a Trailer Suction Hopper Dredge (THSD) dredges material consisting of fine particles, the material can’t settle quickly in the hopper leading to an overflow-loading dredging method with low efficiency.

Through an experiment in the Yangtze River Estuary this study analyses the concentration efficiency of three types of hydrocyclone. The 500-H hydrocyclone separation efficiency reaches above 80%, with a concentration ratio above 2.

The feasibility of engineering application using hydrcyclones is discussed and results predicted.

By using theoretical calculations under the same working conditions, both the loading rates and measured hopper volumes improved significantly. As an example the technology described was applied on work at the Huanghua Port and in theYangtze River Estuary with the prospect of it being more widely applied.

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.
