Seawater Reverse Osmosis (SWRO) Manufacturing Process Water Guide & Calculator

How do you size seawater (salt water) reverse osmosis water systems for manufacturing processes? Sizing and designing a seawater reverse osmosis water system is a complicated process. These calculations are for quick estimates for general sizing, design, and footprints of SWRO water systems. RO feed water chemistry, pressure, temperature and process feed flow rate are a few of the variables that have effects on seawater reverse osmosis system sizing, which are not considered here. Many variables exist that are beyond the scope of the seawater reverse osmosis water guide & calculator below.

Industrial desalination is growing more prominent and is an essential component for reusing and repurposing saline water for critical processes. SWROs also provide sustainable sources of fresh water for various applications, boiler feed, and process water.
