Description 2033-2041
A novel physicochemical disinfection method
based on hydrodynamic cavitation has been identified to disinfect ballast
water. The phenomenon of hydrodynamic cavitation which is associated with the formation, growth
and the collapse of microbubbles, leads to the generation of very high
pressures and temperatures locally, which can cause cellular damage and makes
microorganism nonviable. This paper explores the microbiocidal effectiveness of
hydrodynamic cavitation coupled with
in-situ generated chemicals from sea-water itself for the disinfection
of ballast water with respect to the ballast water discharge standards of the
International Maritime Organization (IMO). Experiments performed in this study indicate
that this method is a potential physicochemical ballast water
disinfection technique. This advanced technology is eco-friendly as it does not
use harmful external chemicals, UV or ultrasound, does not produce harmful
by-products, and is energy efficient, economical, and can be scaled up for
disinfection on very large scale. It is an alternative to current technologies
and can be easily installed on vessels with minimum foot print area, as filtration
and disinfection happen in a single compact unit.
