Green ballast water treatment utilizing waste heat recovery

Abstract

This paper presents a novel green and costeffective ballast water treatment system which will utilize waste heat from propulsion machinery for the destruction of microorganisms in the ballast water in a relatively short time. The high temperature recovered from propulsion machinery combined with the rapid destruction of microorganisms will make the new system more effective than the current similar Ballast Water Management Systems. The research will involve a combination of biological laboratory experiments, numerical simulations, and full scale machinery testing. The project has a potential to lead to the development of methods and knowledge for efficient energy utilization, effective destruction of microorganisms, and reliable methods for sampling and testing of water quality. The latest results obtained demonstrate that the proposed idea works efficiently and effectively, while offering a satisfactory verification with on-site biological experiments.
