DESMI Ocean Guard: The Danish Environmental Protection Agency and Danish Maritime Authority have notified IMO of their decision to amend the earlier type-approval of the CompactClean BWMS manufactured by DESMI Ocean Guard. The BWMS utilises filtration and UV treatment at uptake and UV treatment at discharge and was type-approved on 21 September 2018. This BWMS has now been upgraded to apply filters of the aquaBoll BWT BB filter series manufactured by Boll & Kirch Filterbau as an alternate option to the filters of the ABC filter series manufactured by Filtrex. In addition, three new scaled UV unit models were added to the BWMS. Finally, the BWMS was upgraded to introduce an IMO mode of operation with an alternate UV dose control curve. (MEPC 77/INF.12)
