Nalco - Reverse Osmosis Systems
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.
Onsite Customer Owned Reverse Osmosis Systems The RO Series combines quality design and construction with an integrated control package that delivers a true, engineered system. The complete RO product line is designed for industrial and commercial applications requiring flow rates of 0.7-485 GPM.
Onsite Trailer Mounted Rental Reverse Osmosis Systems This flexible solution provides the highest water quality for trial applications, short-term outages, scheduled outage support, commissioning operations and seasonal water demand requirements. Trailers are provided on a turnkey basis with support for installation, commissioning, operations and maintenance. Our 3D TRASAR technology is integral to the mobile RO trailer, providing the ability to monitor the control system with real time information on the product water quality and quantity. Cellular based remote monitoring allows observation of the system.
Onsite Skid Mounted Rental Reverse Osmosis Systems The skid mounted rental RO system is a flexible solution providing the highest water quality for moderate to long-term needs in a plant. We will assist in the support for installation, commissioning, operations and maintenance. Our 3D TRASAR technology is integral to the skid mounted RO system giving us the ability to monitor the control system providing real time information on the product water quality and quantity. Cellular-based remote monitoring allows observation of the system.
With Quick Link ready devices, this RO system becomes the controller of your water treatment system. By simply activating standard features through a Color Panelview Plus touchscreen HMI, the operation of the pretreatment, RO system, RO tank level, recirculation pump, and post-treatment DI is coordinated, controlled and monitored. Virtually seamless operation of any system is realized.
This RO system is built to last design with a stainless steel frame, high pressure piping, a high efficiency stainless steel multi-stage Grundfos pump with TEFC motor and Dow Filmtec XLE 440 low energy membranes. The following features are available on our industrial 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
