From its initial start-up, the system has been running properly with minimal trouble-shooting. Industrial seawater reverse osmosis systems are mainly designed for the removal of enormous amounts of salt and other impurities from highly inconsumable water sources like the sea. These systems take use of a popular process known as “reverse osmosis” to help in seawater purification. The job of reverse osmosis is to defeat the osmotic pressure of a natural process called “osmosis”. Osmosis naturally pushes salt through a very fine membrane from an area with low saline concentration to an area with high saline concentration. The goal of osmosis is to gain an equal amount of saline concentration on both sides. To stop this natural process, reverse osmosis pushes osmosis in the opposite direction by using a high pressure pump that adds extreme pressure to the highly concentrated saline side of the membrane. The pressure pushes only water molecules through the small pores of the membrane while rejecting salts and other impurities from flowing through. Clean, potable water successfully comes out on the permeate side while salt and the other impurities are dumped into a drain from the concentrate side.


Water Challenges: Water-scarce countries in the Middle East, such as Saudi Arabia, have answered their long-standing water challenges with the usage of seawater reverse osmosis. Seawater reverse osmosis is required in order to remove the extremely high levels of salt in ocean water, which makes it unsuitable for use in food processing, and virtually every industrial application. With greater utilization of reverse osmosis, Saudi Arabia can continue to feed their population by supplying food processing companies with enough high quality water to maintain quality standards in the food and beverage industry.



Applied Solution: An industrial seawater reverse osmosis system was created for a major company in Saudi Arabia. The system came equipped with a cleaning skid. As the feed water enters the system, it is directed to the sideline sediment cartridge filters. Next, the feed continues onto 2X20 horsepower motors with stainless steel pumps to then go through two 4 inch in diameter Hydranautics pressure vessels. The pressure vessels are made in the United States and rated to 1,000 PSI. At the lead end, the system includes a clean in place (CIP) function that cleans the membranes using a specific tank for this very purpose. The system is controlled by a PLC manufactured by Allen Bradley which includes a touch panel screen and a variable frequency drive which serves to protect the motors and results in a more efficient operation. The control panel comprises of complete control over the inlet/outlet valves of each part of the system as well as backwashing routine and alerts that can be set manually to monitor the operations of the system.
