Endless Opportunities for a Sustainable Shipping Industry

Although the shipping industry is effective, considered that it is cheap and can transport large volumes of goods, it is a major contributor to world pollution. The marine environmental impact is significant. Therefore, solutions are required immediately. See the below video to get a grasp of how much one single large cruise ship pollutes.    Advanced membrane technology is one of the keys to decarbonize the world’s shipping industry. This unique...

What is a marine scrubber?

According to the Exhaust Gas Cleaning Association, it is estimated that approximately 10 % of sulfur oxide (SOx) emissions stemming from human activities are caused by the global shipping industry. To lower this significantly, the International Maritime Organization (IMO) has implemented an international sulfur cap.

What Is Open-Loop to Closed-Loop Scrubber Conversion?

With the IMO 2020, marine exhaust gas cleaning systems, also referred to as scrubbers, have become imperative to obtain compliance. Scrubbers can take three forms, being open-loop, closed-loop, and hybrid. Learn more about the differences between an open-loop, closed-loop, and hybrid scrubber. Yet, several countries have banned the use of open-loop scrubbers and scrubber wash water discharge to fight ocean acidification. You can see our complete ...

How Does a Closed-Loop Scrubber Work?

When a ship operates, its engine, auxiliary engine, or boiler generates exhaust caused by combustion processes. Before the shipping industry started to focus on desulfurization, the exhaust gas went directly into the atmosphere, which caused acid rain, harming people, wildlife, and the planet. Today, the exhaust gas can be cleaned with an exhaust gas cleaning system employing unique scrubber technology. A closed-loop scrubber can remove up to 98 ...

What Does a Scrubber Water Treatment Unit Remove?

As a scrubber treats sulfuric exhaust gases, it generates sulfuric wash water. Although the scrubber neutralizes this using alkali, the wash water still contains harmful elements stemming from the combustion process. This is crucial to avoid ocean pollution, which will ultimately harm aquatic species, especially shellfish and corals. A scrubber water treatment unit plays a crucial role in boosting a greener shipping industry for a more sustainabl...
