9 Ballast operation OceanSaver BWTS Filtration Disinfection

10 Filtration 40 micron in-line screen filter, 99.5% efficiency Automatic self-cleaning Filter capacity up to m 3 /h / filter Filter may be delivered for pump room installation with Ex protection Well proven technology developed for BWTS application

11 Flexible installation True in-line filtration Minimal disruption to existing pipework Low service space requirements Installed in any orientation Ex-Safe

12 Automatic self cleaning Self cleaning initiated when differential pressure between inlet and outlet reaches 0,38 bar During cleaning, filter remains in operation Each cleaning cycle takes 3 minutes The dirty water is pumped directly overboard by sludge pump After cleaning cycle is complete, the filter is fully recovered

13 Disinfection Oxidant produced onboard without consumables OceanSaver patented membrane cell technology Extremely efficient maximum level 2.5 ppm Rapid decay of TRO level half time 30 mins Generated oxidant: Hypobromeous species Dosage level self-adjusted by TRO sensors Disinfectant injected in main ballast water stream to kill organisms / phytoplankton
