Low temperatures and feedwater quality, such as high TDS levels will significantly affect the systems production capabilities and performance. Computer projections must be run for individual applications which do not meet or exceed minimum and maximum operating limits for such conditions.

System pressure is variable due to water conditions. Permeate flow will increase at a higher temperature and will decrease at a lower temperature.

Product flow and maximum recovery rates are based on feedwater conditions as stated above. Do not exceed recommended permeate flow.

More information about SWRO

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.
