Currently, scrubbing systems are frequently employed to eliminate particulate matter and harmful substances, such as sulfur oxides and nitrogen oxides resulting from combustion processes in the marine sector. This action is very necessary for ensuring air pollution control.

The areas of scrubber use encompass exhaust management from engines, auxiliary engines, and boilers, both on land and on marine vessels. Thus, scrubbing systems warrant the safety of human life and the environment from harmful toxic matters. Also, sulfur emissions are limited by international regulations.

The International Maritime Organization established regulations that mandate a maximum sulfur content of 0.50% worldwide and 0.10% m/m in regions where air pollution controls are implemented to ensure air quality treatment.

The majority of shipowners install wet scrubbing systems on their ships to comply with international regulations and standards economically. The principle of scrubber operation is based on the use of alkaline scrubbing materials that neutralize acids and remove any particulates from the exhaust gas, then these scrubbing materials are collected with wash water that can be stored or immediately discharged.

All marine scrubbing systems are classified into wet scrubbers and dry scrubbers. Dry scrubbing systems use solid lima as the alkaline scrubbing material while wet scrubbers employ water for this purpose. Wet scrubbing systems can be closed-loop or open-loop.

Closed-loop scrubbers use fresh or seawater as scrubbing material, open-loop scrubbing systems employ seawater. There are hybrid wet scrubbers that can operate utilizing both open and closed running modes either at the same time or switching between them.

Open-loop wet air scrubbers are often used and have numerous benefits such as simple design, easy installation, low maintenance, and no need for waste storage. Unfortunately, the wash water is usually disposed of into the open sea after air treatment.

Regulations in the International Convention on Marine Pollution require to examine the wash water before being discharged to warrant the level of PH. Today the problem of scrubber use is crucial and it is very important to choose the most suitable scrubbing system to be installed on the ship.
