Reverse Osmosis Water Production Calculator

What this calculator estimates

Plan source-water demand for a reverse-osmosis system.

How the calculation works

Feed water equals desired product water divided by recovery as a decimal. Wastewater equals feed water minus product water.

How to use the result

Enter values that represent the current setup, review the calculated result, and compare it with direct measurements and equipment documentation before making changes.

Important limitations

Actual recovery changes with membrane condition, pressure, temperature, feed-water chemistry, flushing and manufacturer settings.

This tool is intended for planning and comparison. Recheck inputs whenever equipment, layout, crop size or operating conditions change.
