Seawater Reverse Osmosis Calculator

Seawater Reverse Osmosis Calculator (R.O.) Guide & Calculator

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

Seawater Reverse Osmosis (SWRO) Systems are flexible for customization. Standard output capacities range from 5,000-300,000 GPD (3.5 GPM – 200 GPM). For detailed SWRO sizing configurations (e.g. single, twin, triple or special multiple skid configurations), control types (Allen Bradley, GE, Siemens PLC, progressive flow, additive flow) or specific specifications like (316L, 304, 316) stainless steel or specific valve & instrument types, email or call Nancrede Engineering at 888-56-WATER (569-2837).
