Nameofproduct:CompactCleanBWMSTreatmentSequence:Ballast water uptake: Filter and UV disinfectionBallast water discharge: UV disinfectionTreatmentRatedCapacity(TRC)oftheBWMS35 – 2500 m3/hFor ballast water uptake, the Treatment Rated Capacity (TRC) of a specific CompactClean BWMS model is limited by the maximum flow rate of either the selected UV unit model or the selected filter model, whichever is lower. The TRC for ballast water discharge is limited by the maximum flow rate of the selected UV unit model.The treatmentflow rate is monitoredby a flowmeterat the BWMSinlet (beforefilter).TypeandmodeldesignationsThe CompactCleanBWMShas the modeldesignationVxxxxxFyyyyN S 00 for modelssuitablefor non-hazardousareas and VxxxxxFyyyy E S 00 for modelssuitablefor installationin hazardousareas, where:Vxxxxxis the applicableUV unit model,refer to Additionalpage 3 of this certificate.Fyyyyis the applicableFiltrexfilter modelor Byyyyis the applicableBOLLFILTERfilter model,refer toAdditionalpage 2 of this certificate.S is the skid mounteddeliverytype, L is the loose componentdeliverytype, D is the deckhousedeliverytypeand M is the low versionof the skid mounteddeliverytype.00 is the standardtype while B0 or BC is used for BWMSinstallationswith a boosterpump and 0C or BC isused for a custommade type (in terms of selectedpipe materials).The CompactClean BWMS is available in two versions: 1) CompactClean(CC): The BWMScan only be operatedin US mode.2) CompactCleanOptIMO(OptIMO):The BWMSmay be operatedeither in IMO or US mode.SystemDesignLimitations1.UV-Intensity(UVI)The CompactCleansystemwill operateat full flow with a UV Intensityhigher or equal to the TRC. At lowerUVI values the flow reductionis applied,Min UV-I compliancelevel alarm is triggered,when UVI is less thanthe approvedranged.The appliedUV dosageis a calculatedfunctionof the UV intensity(UVI) and the exposuretime. Theseparametersare directlyaffectedby flowrateand the UV transmission(UVT)of the water.The CompactCleanBWMShas two compliancemodes:IMO mode and US mode.In IMO mode:1).Thesystemwill be able to operateat full flow from UV-T 1.0 down to UV-T approx.0.62, where after flowis reducedto cope with even lower UV-T.The flow controlis based on the UV-Intensity(UVI) measurementinside the UV unit, and flow reductionis active below UVI 800 W/m2 (Max. TRC UVI).2).The lowest UVI the systemis approvedfor: UVI 170 W/m2.3).Dimmingof UV lamp powerstarts when UVI measuredexceeds900 W/m2,where after lamps will bedimmedto maintaina UVI of 900W/m2±50. The maximumdimmingis 20% of maximumrated power.In US mode:1) The system will be able to operate at full flow from UV-T 1.0 down to UV-T approx. 0.65, where after flow is reduced to cope with even lower UV-T. The flow control is based on the UV-Intensity (UVI) measurement inside the UV unit, and flow reduction is active below UVI 880 W/m2 (Max. TRC UVI).2) The lowest UVI the system is approved for : UVI 227 W/m2.VIEW ONLY
