The most obvious reason for clean water on a ship is for drinking. Crew members and passengers need access to safe, clean water to stay hydrated and maintain good health. Clean water is essential for cooking and preparing food too. Without it, food may not be properly cleaned, cooked or rinsed, leading to foodborne illnesses and other health issues. Beside that, Clean water is also necessary for maintaining proper sanitation on a ship. It is used for washing hands, brushing teeth, and bathing, as well as for cleaning and disinfecting surfaces. There are several ways that ships can obtain clean water while at sea :
- Water tanks
Most ships have onboard water tanks that store fresh water for use by the crew and passengers. The tanks are filled with water before the ship departs and are refilled at ports or by desalination.
Desalination is the process of removing salt and other minerals from seawater to make it safe for human consumption. Ships can use desalination plants to produce clean water from seawater while at sea. This process typically involves filtering the seawater to remove any debris, then using reverse osmosis or distillation to remove the salt and minerals.
Watermakers are portable desalination units that can be used to produce clean water from seawater. They are commonly used on smaller vessels, such as yachts and sailboats.
- Water treatment systems
Some ships are equipped with water treatment systems that can purify water from other sources, such as rainwater or water from rivers and lakes. These systems can remove contaminants and make the water safe for drinking and other uses.
It’s important to note that while the water produced through these methods is generally safe for consumption, it may still contain traces of impurities and minerals that can affect the taste and quality of the water. Regular testing and treatment of the water is necessary to ensure that it is safe for consumption.
