Summary Tools used
The use of filters or hydrocyclones forms a good
treatment step in ballast water treatment that can be
applied at all conditions that can be expected during
transport between the freshwater Great Lakes and the not specified
marine Arctic. additional treatment physical or chemical
is always required.
Carbon filter has better performance than crumb rubber
filter in filtering sea water.filtration method is
not able to reduce the value of water turbidity that

conduct by microbes in OD level 0.070.the treatment of
filtration and UV radiation the OD level will decrease to
0,010.
decreasing the media size and adding a coagulant could
improve the removal efficiency, but these approaches
will result in a higher head loss and subsequently a lower

Xow rate. ncreasing fitration rate reduced removal
efficiencies to some degree, and increased
head loss notably
using activated carbon in the vessel may use a filtration system
that can function as a cartridge. IMO
standards which define discharge clean ballast water can be not specified
met by using a filtering system based
activated carbon.
The single-dose treatment did reduce the number of
algae in the test water, but not sufficient. The
efficacy of the in-tank treatment was significantly better.
Bacteria and
not specified
algae were nearly completely eliminated. the highest
maintenance dose was needed in the test with brackish
water, whereas the total dose in freshwater and marine
water was comparable.
The method successfully reducedthe oxygen level within
the tanks and the water in the trea-ted tanks was anoxic
at the end of the trial. There was anunexpected decrease
in the number of viable bacteria inthe treated tanks after
not specified
about 5 days. The results of this study clearly
