How does reverse osmosis work?

Reverse osmosis works by forcing water under pressure through a semi-permeable membrane with pores of approximately 0.0001 microns. This pressure overcomes osmotic pressure and forces water molecules through while rejecting dissolved salts, heavy metals, bacteria, viruses, and most contaminants. The purified water (permeate) passes through; the concentrated waste water (brine/reject) is discharged.

What pressure is needed for a commercial RO system?

Commercial brackish water RO systems typically require 150-300 PSI. Seawater desalination systems require 800-1,000 PSI due to the higher osmotic pressure of seawater (approximately 400 PSI at 35,000 ppm TDS). Required pressure depends on feed water TDS, temperature, and target recovery rate.

What is recovery rate in a reverse osmosis system?

Recovery rate is the percentage of feed water converted to purified permeate. Commercial RO systems typically operate at 50-80% recovery. Higher recovery means less waste water but increases scaling risk. The optimal recovery rate depends on feed water chemistry and the presence of scale-forming ions like calcium, barium, and silica.

What contaminants does reverse osmosis remove?

Reverse osmosis removes 95-99% of dissolved salts, heavy metals (lead, arsenic, chromium, mercury), nitrates, fluoride, bacteria, viruses, chlorine, chloramines, pesticides, and pharmaceutical compounds. It does not remove dissolved gases like CO2 or VOCs without additional treatment stages.

Where can I buy a commercial reverse osmosis system near me?

AMPAC USA manufactures and ships commercial reverse osmosis systems from Woods Cross, Utah. We serve customers across the United States, Canada, and over 100 countries worldwide. Contact us at (877) 611-8530 or visit ampac1.com for pricing and custom sizing.

How much does an industrial water purification system cost?

Industrial RO water purification systems from AMPAC USA range from $5,000 for small commercial units to over $500,000 for large-scale seawater desalination plants. Cost depends on flow rate (GPD), feed water quality, and application. Request a free quote at ampac1.com/contact-us.
