Dona Paula (Goa): India has developed an eco-friendly technology to treat sea water brought in by cargo ships.

It is also to treat radioactive elements that harm the marine ecosystem or can have even bigger consequences.

Ballast water, as the sea water brought in by the ships is called, is sea water admitted into tanks at the bottom of the ship to stabilise it for the high seas.

According to A.C. Anil, scientist at the National Institute of Oceanography (NIO), the technology which is developed by the NIO in association with the Pune-based National Chemical Laboratory and Mumbai University Institute of Chemical Technology can kill the alien organisms to the level prescribed by the International Maritime Organisation (IMO), a UN body.
