Seawater desalination utilizes permeable membranes, which are only tasked to remove dissolved solids while dividing the feed water into purified water and the rejected concentrated salts. The salts and other organics are thrown into the brine stream then flushed into a drain. At the end we have purified water that has 99% less dissolved salts. These seawater reverse osmosis systems are immensely powerful, with the capacity of purifying significantly high TDS water.
Seawater RO systems are usable anywhere from yachts to municipalities. It’s important to choose the correct materials of construction to handle seawater (which is highly corrosive). We use materials such as SS316L, Duplex SS 2205, SS 2207, and SS 904 to guarantee a longer operating life and less maintenance.
Commercial SWRO-C is equipped with premium components which include duplex SS centrifugal-type high pressure pump for high performance and corrosion resistance, a programmable computer controller with many built-in features, 1000 psi fiberglass membrane housings for durability and US made seawater membranes for high quality product water.
Our SWRO4 Series is available with capacities ranging from 380 GPD to 10,000 GPD and a maximum feed water TDS of 45,000 ppm. We offer standard units as well as customizable to fit you water application needs.
In choosing the correct SWRO model, the following information must be provided:

What is seawater reverse osmosis?
Seawater reverse osmosis systems are designed to decline more than 99% of saline compromised within the feed water. These systems also incorporate a rinsing, chemical purifying apparatus to eliminate sodium chloride, avert scaling, and preserve system performance. There are two fundamental elements within every seawater reverse osmosis system, which are reverse osmosis membranes and high pressure feed pumps. These elements make up the center of any reverse osmosis system and need special consideration and application for successful operation.
Does reverse osmosis remove salt from seawater?
Yes, semipermeable membranes enable the feed water to pass through it at a much higher volume than dissolved salts. Reverse osmosis systems work by applying pressure as freshwater streams through its membranes to filter out the concentrated saline in the feed water, as well as minerals and pollutants. These unwanted impurities are either flushed away, recycled, or processed. Seawater reverse osmosis systems utilize more than one membrane to boost the load of purified water turned out each day.
What are the advantages of desalination plants?
Seawater desalination has become a vital alternative to the production of pure freshwater throughout the areas of the world without drinkable water. As other sources such as rivers, lakes, wells, and springs have become more exhausted due to excessive extraction, the ocean has provided an abundant supply of available water for human use. Although ocean water consists of elevated levels of salt, and therefore is unable to be utilized for consumption or most other purposes, seawater desalination has helped make it practical.
