What is a Salt Water RO Systems?

Salt water, also known as seawater, is a complex mixture of 96.5% water, 2.5% salt, and dissolved inorganic and organic matter, particles, etc. Salt water reverse osmosis systems eliminate the vast majority of suspended matter, debris, and colloids from seawater through reverse osmosis technology. The salt water is desalinated to produce usable fresh water for the purpose of providing a portable water supply to alleviate the shortage of fresh water

The system consists of high-pressure pumps, high-quality reverse osmosis membranes, and pretreatment filters. NEWater offers different types of seawater reverse osmosis systems customized to handle different types of salt water.

How Do Salt Water RO Systems Function?

Salt water reverse osmosis systems utilize reverse osmosis membrane technology to apply pressure to the raw water to reverse the typical osmotic pressure before the water is forced through a semi-permeable membrane. Dissolved salts and other unwanted impurities in seawater are eliminated as a high-pressure pump acts as a pressure driver allowing the raw water to enter the membrane system, thereby separating the impurities from the pure water molecules.

The impounded contaminants are retained on one side of the membrane, while the pure water is collected as the other side of the reverse osmosis membrane. Salt and other organics are flushed into the drain with the brine stream.

How does NEWater Design a Solution for You?

Our systems are custom manufactured and use RO technology to remove impurities from salt water. Typically we consider many factors when designing a salt water RO system. First, and extremely important, is the source of the feed water. Usually, after knowing what the quality of the feed water is, the water quality requirements of the produced water and the application site of the equipment are determined. Once you have determined the goal, you will be able to develop a plan.
Finally, we will provide the best design solution for your business based on your water treatment volume requirements, electricity specifications, budget, and the structure of the system.

Customize Your Salt Water RO System Today!

Over the years, natural fresh water reserves have depreciated significantly, forcing billions of people to seek alternative sources of fresh water. As more and more areas such as equatorial regions, arid environments, island coastal communities, remote resorts, etc. are becoming aware of the need for desalination. In the following, we will answer some of the most frequently asked questions on the Internet about salt water reverse osmosis systems.

Can a Saltwater RO System Produce Drinking Water?

Yes, a salt water RO system extracts a host of objectionable impurities, including dissolved salts, bacteria, viruses, chemicals, and suspended matter, to produce clean and safe drinking water. However, a supplemental system may be required to complete the filtered water produced by the RO system. For example, an ultraviolet disinfector can kill 99.99% of the microbial contaminants in seawater.

What is the Cost of Salt Water Reverse Osmosis Desalination?

The cost of Salt Water desalination can vary, and it depends on the method used and the size of the operation. For small-scale operations, costs can range from $0.50 to $2.00 per gallon (3.8 liters), while large-scale operations can cost as little as $0.15 per gallon (3.8 liters).

Cost of Salt Water Reverse Osmosis Desalination

How Much Power do Salt Water RO Systems Consume?

The energy consumption of salt water RO systems has been decreasing over time as newer and more efficient technologies are developed. For example, the SEC of membrane-based salt water RO systems has decreased from about 3 kWh/m3 in the early 2000s to around 1.5 kWh/m3 today. This decrease is due to improvements in membrane technology and design, as well as a better understanding of salt water RO plant operations.
