Turning Saltwater Into Freshwater With RO Systems

Although seawater covers 71% of the earth’s surface, this water is not potable. An immense amount of ocean water can surround you, yet it cannot be consumed or used for cleaning.

All boats, whether 25-foot pleasure boats, million-dollar yachts, or anything else, require fresh water. Knowing how to convert saltwater to freshwater with RO filtration is crucial for anyone who plans to be at sea for an extended period.

So how do these systems operate? How is it possible to turn saltwater into freshwater? As industry leaders continually developing and producing better and better products, we are here to provide you with all the information you require to take the most out of RO systems.

What Is an RO System?

Concerns about how to purify seawater for use in various onboard applications rank high on the list of issues faced by cruisers. For those problems, RO systems are always the best choice.

Reverse osmosis (RO) systems are the most popular filtration system in the industry, and they work by passing saltwater through a series of membranes.

The membranes have tiny pores that allow water molecules to pass through, but not salt or other contaminants. A pressure pump is used to push the water at a high enough pressure to force the water molecules through the membrane while trapping the salt and other contaminants

The freshwater is then collected in a holding tank while the salt and other contaminants are flushed away.

Turning Saltwater Into Freshwater: How does it work?

The process behind RO systems may appear to be a simple task, but the truth is thatthey are quite complex. As much as we’d like to, we can’t simply take the salt out of the water, just like you couldn’t dissolve sugar from your morning coffee.

The following is a step-by-step of the Reverse Osmosis Process.

  1. Intake: The first step is the intake, where saltwater is taken from the source via a pump.
  2. Filtration: Next, the water is filtered through a sediment filter that removes larger particles such as dirt, rust, and other debris.
  3. Pre-treatment: The water then passes through a carbon filter to remove chemicals, odors, and tastes from the water.
  4. Reverse Osmosis: The water is then sent to the reverse osmosis membrane, which is pressurized to force the water molecules through the membrane, leaving behind contaminants such as salt and other minerals.
  5. Post-treatment: The clean water is then sent to a post-treatment filter for polishing before being collected in the holding tank.
  6. Storage Tank: The purified water is now stored in a sealed tank.

The Benefits of Using a Reverse Osmosis System 

1. Provides Better Use of Resources

There are numerous benefits to using a reverse osmosis system, the most obvious being that it can turn saltwater into freshwater. This makes it an ideal choice for boats, as they can remain at sea for extended periods without worrying about running out of fresh water. 

2. It Is a Cost-Effective Solution

RO systems are highly efficient and cost-effective. Many components are designed to last for years and require minimal maintenance.

3. It Guarantees a High-Quality Result

The RO system also removes many contaminants, including lead, nitrates, chlorine, and other chemicals. This means you can filter salt water to make it drinkable, reducing the risk of gastrointestinal illnesses.
