Abstract:
An apparatus for treating water to be supplied to a ballast tank and for reducing silt and sediment build-up in the ballast tank, comprising:means defining a water pathway having a main inlet for connection to a body of navigable open raw water containing sediment and marine organisms, and a main outlet for connection to a vessel's ballast tank(s); separator means in the pathway and having a separator means inlet for receiving the raw water, the separator means separating sediment with some water from the raw water to produce initially processed water which contains at least some marine organisms, the separator means having a first outlet for supplying the initially processed water to the pathway, and a second outlet for returning the sediment with some water to the body of raw water; biocide means connected to the first outlet and in the pathway downstream of the separator means from the main inlet, for receiving the initially processed water and for disabling the marine organisms in the initially processed water to produce treated ballast water; and ballast pump means connected to the pathway, in line with the biocide means for pumping water along the pathway between the main inlet and the main outlet, and through the separator means and the biocide means.
