Reverse Osmosis vs. Water Softeners for Yachts: Which is Best?

Updated: Feb 13, 2023

When it comes to providing clean and safe water for your yacht, there are a few options to consider. The most common are water softeners and fresh water reverse osmosis systems. Both of these systems are designed to treat unwanted substances in the water, but which one is best for a yacht? In this post, we will be discussing the benefits of a reverse osmosis treatment system over a yacht water softener. We will look at how reverse osmosis works, what it filters out, and why it is a better choice than a water softener for yachts.

What is a water softener?


A water softener is a device designed to treat calcium and magnesium in hard water, also known as "hard water calcification". It works by passing the hard water through a tank filled with small beads of resin which ionize the metals and reduce calc deposits. This softened water is then used for yacht wash down and other applications, including rinsing, automatic water purifiers, dock water, and more. Soft water makes it easier to wash your boat and spot free water makes windows clear and the overall boat look cleaner. The benefits of soft water are clear: no calc deposits, clearer windows, and cleaner water. Plus, a water softener can help prevent calc buildup over time, making it a great long-term investment in boat water filtration and washdown systems.

What is reverse osmosis?


Reverse osmosis (RO) is a water purification technology that utilizes a membrane to filter out impurities from water. Unlike water softeners, reverse osmosis does not add anything to the water and instead removes particles such as salts and ions. RO systems are becoming increasingly popular on yachts due to their ability to produce clean, purified water that is perfect for washing and other activities. A reverse osmosis system can be used to supply pure dock water and easy yacht wash. The end result is soft water and pure that is spot free and free of calc deposits, providing crystal clear windows and easy washing. With no calc to prevent it, reverse osmosis provides a superior washdown system compared to water softeners.

What are the benefits of each?


Water softeners have been traditionally used to provide boat owners with soft water for washing and cleaning, as well as providing calc prevention. Soft water reduces the risk of calc deposits forming on boat surfaces, allowing for easier washing and spot free water. While soft water can help reduce the risk of calc deposits, it will not eliminate them entirely.

Reverse osmosis is a newer technology that offers yacht owners and crew a more comprehensive solution for their water purification needs. puRO is an automatic water purifier that removes all impurities from dock water, including calcium and magnesium. By removing all of the mineral deposits and other impurities from the water, yacht owners and crew are able to enjoy clear windows, clean water, and even spot free washdown.

When considering the benefits of each option, reverse osmosis offers a more comprehensive solution when it comes to yacht water filtration. This is especially beneficial if you use a washdown system or regularly clean your windows. Reverse osmosis also offers the added benefit of being much easier to maintain than a traditional water softener.

Which is best for yachts?


When it comes to choosing a water purification system for your yacht, both reverse osmosis and water softeners have their benefits. Reverse osmosis is best if you want to achieve spot-free results with your washdown system, as well as providing crystal clear windows and an easy washing experience. Water softeners are ideal if you're looking for a calc prevention solution, as it will help prevent calc deposits and provide soft water for washing.

Reverse osmosis treatment is the most effective way to purify dock water or seawater for yacht wash. An automatic water purifier provides the highest level of water purification, making it suitable for all types of boat water filtration needs. The filtered water will be free from calc, minerals and other impurities, making it ideal for a spot-free washdown system.

Water softeners are also a great choice when it comes to yacht wash. Soft water helps keep surfaces cleaner for longer periods of time, as well as reducing cleaning times. The soft water also helps to prevent calc build up in areas such as sinks and showers. While reverse osmosis treatment can be beneficial for achieving spot-free results, a water softener is often the best solution for maintaining clean and clear water.

Both reverse osmosis and water softeners have their benefits when it comes to yacht wash. Depending on your needs, one may be better than the other. Reverse osmosis provides spot-free washing and crystal clear windows, while a water softener will help reduce calc build-up and provide soft water for washing. Consider the specific requirements of your yacht before deciding which option is best for you
