Seawater Reverse Osmosis (SWRO) Potable Water Guide & Calculator

How do you size a potable seawater (salt water) reverse osmosis drinking water desalinization system? Because drinking water sources are subject to contamination, sizing and designing a seawater reverse osmosis drinking water system is not a straight forward process. Many variables exist that are beyond the scope of the seawater reverse osmosis potable water guide & calculator below.

These calculations give you fast estimates for general sizing, design, and footprints of SWRO potable water systems. Desalinization 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. Other calculators for specialized industrial, ultrapure reverse osmosis systems can be found here:

At Nancrede Engineering, we’ll find the perfect reverse osmosis system for all your most critical high purity water needs. 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 control types (Allen Bradley, GE, Siemens PLC, progressive flow, additive flow), skid configurations, or specific materials of construction, like (316L, 304, 316) stainless steel, or specific valve & instrument types, email or call Nancrede Engineering at 888-56-WATER (569-2837). Our sales engineering team consists of degreed mechanical engineers, experts in water treatment and processes for seawater reverse osmosis systems including pre-treatment equipment like carbon filters, ultraviolet (UV) lights, pumps, bacterial sub-micron filters, ultrapure water storage tanks.

Nancrede Engineering also offers preventative maintenance, equipment leasing, financing, engineering consultation and build, own, operate options. Let us know if you would like information on how these services can help you reduce capital risks and downtime.
