| Summary: | Treatment of ballast water using engine waste heat has been deliberated upon but studies are not substantial. This study presents extension of a treatment system from an existing system with additional components. Tests at laboratory level had been carried out to test the treatment effectiveness in the stages identified for species’ elimination. Average heat recoveries from exhaust gases worked to between 15 to 33% of input energies. Tests on species demonstrated >95% mortalities in the temperature range of 55 to 75°C. This paper discusses the viability of the developed system based on the test results and the IMO’s requirements. The positive outcomes of the tests are encouraging and further studies are proposed. Keywords : Heat treatment; Impeller effects; Species’ mortalities |
