Sea Water Reverse Osmosis Systems

From watermakers to industrial sized Sea Water Reverse Osmosis Systems, we offer a full range of sea water reverse osmosis systems.


Seawater reverse osmosis systems are manufactured to eliminate a large amount of salts and other minerals from sea water using a method called reverse osmosis. The method of reverse osmosis consists of employing a high pressure pump to add high pressure to salty water forcing it through semi-porous membranes denying salts and other organics from flowing through. The ocean’s specific TDS and its temperature indicated the amount of pressure that needs to be added. The membranes are only tasked to remove dissolved solids while dividing the feed water into purified water and 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 sea water reverse osmosis systems have the power to purify extremely high TDS water.


Sea water reverse osmosis systems are scalable from Yachts to Municipalities). These systems should be manufactured with a proper process design, and its important to choose the correct materials of construction to handle seawater which is highly corrosive. Pure Aqua, Inc. uses materials such as Duplex SS 2205, or SS 2207 or Monel, and SS 904.  Choosing the proper material of construction guarantees a longer operating life and less maintenance. Pure Aqua Inc. supplies a full range of commercial and industrial sea water reverse osmosis systems, customized to the end user’s specific requirements.   Pure Aqua, Inc.’s team has 90+ years of combined experience in the sea water reverse osmosis industry.
