Uses for Industrial Sea Water Reverse Osmosis SWI Series

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. 

Pure Aqua is ready and able to provide only the best in industrial sea water reverse osmosis systems.

Video on Industrial Seawater RO Units Pakistan

This project consists of 3 Industrial Seawater RO Units for a for a drinking water facilities in Pakistan producing drinking water less than 350 PPM TDS. Each Seawater Unit produced 200,000 GPD with a maximum 40,000 PPM feed water TDS. Feed water to the units are from a seawater beach well. All three Industrial Seawater Units were selected from our SWI Series and they came complete with an advanced PLC, multimedia prefiltration, FRP tanks, prechlorination, dechlorination, acid dos..more->
