Seawater/Brackish Water Reverse Osmosis

Reverse Osmosis, also known as hyper filtration, is the preferred method of seawater and brackish water purification. As the equipment needed to perform reverse osmosis is cost-effective, and the process requires little input energy compared to other methods of purification, reverse osmosis has become the worldwide leader among desalinization methods. Developed at UCLA, and used commercially since the 1970’s, seawater reverse osmosis has served marine professionals for nearly 40 years. Seawater Reverse Osmosis (SWRO) is used in a wide range of commercial applications. Marine professionals such as commercial fisherman and offshore rig workers rely on SWRO to provide freshwater for routine daily tasks such as bathing, cleaning and of course, drinking. In larger applications, such as cruise ships, SWRO is sometimes also used. In such applications, it is necessary not only to desalinize water, but to provide quality freshwater. Cruise liner restaurant professionals count on SWRO for water used for cooking, as well as making coffee, soda and other beverages. Here, consistency is key. By way of its simple yet effective design, reverse osmosis is able to consistently satisfy the needs of those who count on it. The process itself is relatively simple and straightforward. In order to purify a liquid, the “solvent” (in this case, water) is put under pressure in excess of 250 psi for brackish water and 1000 psi for seawater, forcing it through a semi-permeable membrane. This application-specific membrane allows water molecules to pass through, but catches “solutes,” yielding purified water. When employed, reverse osmosis is capable of not only of de-salting water, but also removing other impurities such as bacteria, ions and particulates.

  1. Reverse Osmosis is ideal for producing low conductivity/Total Dissolved Solids (TDS) with little maintenance from relatively high conductivity/TDS water.
