Pure Aqua - Model SWI -Industrial Seawater Reverse Osmosis Desalination Systems

Seawater Reverse Osmosis

Seawater Reverse Osmosis (SWRO) is a reverse osmosis desalination membrane process that has been commercially used since the early 1970s. The typical single pass SWRO system consists of the following components:

• Intake: well or open water

• Pre-treatment: Filtration and chemical dosing

• High-pressure pump: to achieve the needed pressure

• Membrane assembly: to perform the desalination process

• pH adjustment: to adjust the alkalinity or acid level

• Disinfection: to prevent any bacterial or organic growth

Pure Aqua, Inc. has manufactured and supplied hundreds of commercial and industrial seawater reverse osmosis systems with feed water TDS up to 45,000 ppm. 

Customizable RO System Capacity

Our SWI Series is available with capacities ranging from 8,000 GPD to 660,000 GPD and a maximum feed water TDS of 42,000 ppm. We offer standard SWI Series units as well as customizable to fit you water application needs. From your five star resort to the world`s largest desalination plant in the United Arab Emirates, Pure Aqua is ready and able to provide only the best in industrial desalination systems.

Pure Aqua’s Sea Water Reverse Osmosis Systems are capable of removing salts as well as other impurities such as bacteria, sugars, proteins, dyes and constituents that have a molecular weight greater than 150-250 Dalton. Pure Aqua supplies a full line of standard and customizable Sea Water Reverse Osmosis systems, all of which are engineered using advanced 3D computer modeling and process design software for accurate and customized solutions.
