Anti turbidity bell

10/12/2008
The maritime port, whatever the functional profile may be, causes an elevated and complex environmental impact. Elevated for the concentration of the activity that takes place there.
Parallel to the problem of the draining of the materials resulting from the port dredging, it is assuming greater importance the necessity of protecting the marine ecosystem during the operations of excavation.
The water turbidity in the zones adjacent to the dredging operations is a problematic always existed, that only in the last period is assuming, at a planning level, a particular importance valence. The possible damages caused to the present flora and fauna in the zone of the living operations are considerable and its consequences are seen on the long period.
The marine sediments, in fact, are contaminated by metals, hydrocarbons, nutritious, bacteria, chemical substances of synthesis. Pollutants that for the majority are toxic, persistent and susceptible of accumulation in the living organisms. An activity of excavation not characterized by a limitation of the turbidity of the water surrounding the work site could cause serious damages to the marine ecosystems.
This problem has been recently faced during the realization of a dredge for the temporarily society of firms to whom the dredging of the west bay of Brindisi Port (Italy) have been adjudged. In order to limit and control the water turbidity during the phase of dredging, an anti-turbidity bell has been applied to the dredging pump. This bell, keeping the performances of the pump unaltered, allows to limit to a circumscribed area for the pump suction the turbidity deriving from the excavation operation.

This bell is the umpteenth example of a ready and immediate answer, from DRAGFLOW, to the changeable demands of our partner.
