UPRENT SOLUTION

During the cleaning of the basin’s bed the most attention is drawn to cleanness and operational accuracy, while dredging is done mostly to extract the underwater minerals, so the attention is drawn to the capacity – m3/h. In this case, UPRENT team chose to install a dredge with electric engine pump thus enhancing the dredging capacity with the high-head jet-ring stream.
