Wärtsilä Corporation and Trojan Technologies have signed an exclusive agreement to jointly develop, market, and distribute a ballast water treatment product for ships. The two companies will gain synergistic benefits from the combined strength of Wärtsilä's global reach and presence in the marine market, and from Trojan Technologies' leadership and experience in developing ultraviolet treatment solutions. The ballast water treatment product is presently in pre-production, with third-party validation to take place in late 2010. The innovative ballast water treatment product is expected to enter the market at the end of the year. Changing regulations in the marine industry have driven the need for this new ballast water treatment product.
