Technology line DESET PG03 is intended for continuous treatment of bottom sediments, therefore the name (DESET – DEwatering SEdiment Technology). The coupling of this innovative dewatering technology with a suction dredger brings solutions for removal and treatment of bottom sediments of various characteristics.

The technology unit DESET PG03 employs a two-phase technological process. The processing of sediment starts with a separation of coarse fractions on vibrating screens. Then comes the separation of water from solids [in the sediment] in a decantation centrifuge Flottweg Z73. The use of a polymer solution maximizes the production of dewatered sediments and provides the required quality of the filtrate. PG03 uses biodegradable lubricants thus it does not damage the environment at any stage of its lifecycle.

The DEWASYS® software based on the SIMATIC control system (TIA Totally Integrated Automation) by SIEMENS controls the technology centrally. DEWASYS® provides for the functionality and unified operation of individual elements of the unit. At the same time it monitors and archives its operational data in one place. Common dump trucks subsequently transport the dewatered sediment for disposal or further use. The cleaned separated water (filtrate) returns back in the water body.

The DESET PG03 unit is designed and adjusted for standardized shipping containers. This feature enables its transport by trucks, railway or waterway. Thanks to this, the DESET unit can be adapted to the requirements of every project in terms of space and performance.
