Tests of PureBallast were concluded in Q2 and were performed using the USCG-approved CMFDA/FDA (staining) method. All testing was conducted at DHI in Denmark using the same hardware, power consumption and flow as the IMO-approved version of the system.
 
The company says that PureBallast has achieved high-performance results without any change to its components or system design. The tests show that PureBallast provides reliable biological disinfection at full flow, whether by IMO or US Coast Guard standards.
 
Alfa Laval is now compiling its USCG type approval application, including the CMFDA/FDA test results for PureBallast 3.1, for submission to the USCG in the near future.
