Industrial Reverse Osmosis Sizing Guide & Calculator

How do you size an industrial reverse osmosis system? The following Industrial Reverse Osmosis (RO) water sizing calculations can be used as a rough guide for industrial water reverse osmosis systems.

To view other industrial calculators such as industrial water softeners and iron, carbon, and ML filters, see the industrial and high purity water guides and calculators page. To see more detail on industrial and high purity reverse osmosis systems, go to the reverse osmosis page here.

There are multiple variables in sizing ultrapure & industrial reverse osmosis systems that are beyond the scope of the RO calculator below. Examples include water pressure, temperature, flow rate, and available foot print. Therefore, these industrial RO guides should only be used for quick estimates.
