Reverse Osmosis
Nalco Pretreatment Solution (PTS) is a leading supplier of industrial reverse osmosis (RO) systems and commercial reverse osmosis systems to efficiently remove dissolved solids and contaminants from water in industrial and commercial applications. Standard and custom commercial RO systems with capacities from 375 gallons per day (GPD) to 700 gallons per minute (GPM) are available.
Nalco PTS industrial and commercial RO systems incorporate the latest technology to remove dissolved minerals, particles, organics, solids and other contaminants from water. RO uses reverse osmosis membranes as its core separation technology to reject these contaminants.
Nalco PTS Reverse Osmosis options include purchasing one of our standard RO systems or renting one of our modular RO systems.

Typically, a reverse osmosis system requires pretreatment – water softener, carbon filter and possibly some post treatment – polishing ion exchange resin bed. The configuration of the RO and the pre- and post-treatment will vary and depends on the end use of the RO-treated water. All necessary pre- and post-filtration equipment for your application is designed by Nalco PTS engineers and assembled at our factory. It is then incorporated into the RO system package to ensure complete functionality and efficiency of the RO system.
The ideal applications for RO water filtration equipment include:
- Manufacturing
- Laboratory
- Electronics
- Pharmaceutical/biotech
- Automotive
- Textile
- Hotels, resorts, schools
- Food processing
- Beverage/bottling
- Chemical blending/manufacturing
- Mining
- Boiler feed water
- Ion exchange pre-treatment
- Beverage production
- Spot free product rinse
