near marine 3 Cost-saving new flexibility with PureSOx When the first vessel set sail with Alfa Laval PureSOx ten years ago, it had a hybrid system on board. Capable of operating in either closed or open loop, hybrid systems balance the ability to meet tougher discharge regulations with total operating economy. Today, a new PureSOx water cleaning system (WCS) offers more cost-saving flexibility than ever. Closed loop with open possibilities In 10 years at sea, Alfa Laval PureSOx has shown that SOx limits can be met while operating on more economical high-sulphur fuel. Likewise, it has proven that closed-loop operation is both possible and feasible. Many PureSOx customers have chosen hybrid systems with closed-loop modes, while others have chosen hybrid-ready systems, which simplify later upgrading from an open-loop to a hybrid system. Now PureSOx has grown even more flexible when it comes to closed loop, thanks to a new modular and upgradeable PureSOx water cleaning system (WCS). It combines high-speed separation – an Alfa Laval core technology which is the most effective means of water cleaning – with flocculator and membrane options, plus the ability to handle both Mg(OH)2 and NaOH as alkali, and to choose between seawater or fresh water. In short, the new PureSOx WCS provides the most cost-effective solution for both present and future needs.

Next year on 28 October, the IMO revised G8 guidelines for ballast water treatment systems enter into force. Alfa Laval PureBallast 3 was the first solution ready – and remains one of the few that is. When considering ballast water treatment systems, ship owners need to think carefully about when they will be installed. Just one year from now, any system without IMO revised G8 approval will be banned from installation. Since the IMO rules are global, the wrong choice of system will put most world ports out of reach. The new requirements are far more stringent, which means the path to type approval may be long. PureBallast 3 has been revised G8 ready since early 2018, but so far only a handful of suppliers have followed Alfa Laval’s example. With revised G8 certification in hand, PureBallast 3 customers can look ahead with confidence. Moreover, they can look to PureBallast 3 to meet their other challenges. The past year has seen many new advances, including a 1500 m3/h reactor, minimized holding time in United States waters and deckhouse solutions with an optional booster pump unit.
