Naturally, osmosis transports salt through a semi-porous membrane from a region with low saline concentration to a region with high saline concentration. Its objective is to gain an equal amount of saline concentration on both sides. This is when seawater reverse osmosis comes in to reverse this process. First, seawater is passed through several pre-filters to take out particles and solids from the water. Next, water proceeds into a water softener tank to remove hardness that can cause damage to the membranes within the system. Lastly, it goes into the seawater RO system where the semi-porous membranes take out the particles that the pre-filters bypassed. The membranes capture salts, organics, and other impurities and only permit water to flow through. At the end we have potable water emerging on the permeate side while salt, organics, and other impurities are discharged into the drain from the concentrate side.

The most expensive real estate areas in the world is not in major known cities; it is on off-shore platforms and ships, where every square meter or foot can cost hundreds or thousands of dollars. An increasing number of platforms and marine vessels rely on seawater reverse osmosis (SWRO) systems to extract fresh water from seawater. Marine vessels require the SWRO system to generate fresh water, applications: commercial marine, military, livestock. SWRO system reliability is very important to ensure adequate clean fresh water for personnel as well as process equipment. However, the cost of on-board space value demands the most space-efficient SWRO package possible. The high-pressure pump (HPP) provides the driving force to produce permeate fresh water from the SWRO membrane, and is key to achieving reliability and compact size.

Water Challenges: Fish farms require a great deal of high quality water in order to achieve effective cleaning of large quantities of fish brought from the sea before being supplied to the market. Fish cleaning is required to remove high levels of contaminants that include micronutrients, proteins, and nitrogens. Concurrently, the water treatment technology such as reverse osmosis has significantly enhanced fish farm processing. Due to these technologies, fish production and trade can be done much more productively throughout the world.

From its initial start-up, the system has been operating accordingly with minimal trouble-shooting. Seawater reverse osmosis is a simple method that involves eliminating a numerous amount of salt and other minerals from water sources that are highly non-consumable. A high pressure pump is utilized to combat the osmotic pressure of a natural process called “Osmosis”.
