De Nora pointed out that it is the originator and patent holder of electrochlorination disinfection of ballast water through the slipstream method, whereby only 0.5% to 1% of the seawater flow entering the ballast line needs to be channelled into the electrochemical unit. The necessary amount of hypochlorite required to treat the water is generated in the slipstream and is then mixed to the full volume of ballast water.

The company said its proprietary method offers an effective solution for ships with large ballast tanks and high pumping rates, particularly large tankers, bulkers and LNG carriers, avoiding the need to store hypochlorite onboard, achieving increased efficiency and avoiding waste.

“The flexible configuration of the Balpure system makes it suitable for new build and retrofit projects alike, whilst the operational adaptability delivers significant Opex benefits over competing technologies,’ added  Stelios Kyriacou, gm of De Nora Ballast Water Management Systems.
