DESMI has revealed that its RayClean ballast water treatment system (BWTS) may receive acceptance by the United States Coast Guard (USCG) in Q1 of 2017 if the Most Probable Number (MPN) method for testing BWTS is accepted following ongoing discussions with United States authorities that come after their initial rejection of the method in July this year.
During the summer DESMI tested the RayClean BWTS with the FDA/CMFDA method, with results showing its ability to enumerate viable organisms in high UV-transmittance waters. However, low UV-transmittance waters that are found in many ports around the world were also used to test RayClean with the MPN method, showing the BWTS’s ability to reduce organism in low UV-transmittance waters as low as 33%.
However, if the discussions result in a non-acceptance of the MPN method, DESMI has revealed that it will re-test a modified system during 2017 to receive USCG approval in Q1 of 2018.
