ECO RO
DOW FilmTec ECO elements feature next-generation membrane technology offering the highest quality permeate at 30% lower energy consumption.
Using new membrane chemistry and low dP feed spacers, DOW FILMTEC ECO elements help deliver significantly lower energy costs and reduced chemical consumption in downstream polishing costs. With 99.7% rejection at 150 psi, ECO elements provide robust performance over longer element life. At highest quality, they deliver 40% lower salt passage at 30% less energy compared with standard RO elements.
Plants that switch from conventional RO elements to DOW FILMTEC ECO elements enable lower energy usage and reduced regeneration costs.
Benefits of DOW FilmTec ECO Reverse Osmosis Elements
“Plants that switch from conventional reverse osmosis elements to FILMTEC ECO join a unique population of thriving plants that have less impact on the environment and less strain on their bottom line.” ~ Rajat Mehta, global product director for Dow Water & Process Solutions

- Reliable and long-term seal integrity – The single, non-sliding seal reduces the number of potential leak sites and is evenly compressed upon installation.
- Leak-tight performance – The iLEC design eliminates the possibility of o-rings being rolled from their grooves or pinched and damaged during operation.
- Lubricant-free operation – Omission of o-ring lubricant to preserve permeate quality, such as in ultra-pure water applications, will not compromise sealing performance.
- Backward compatibility – Compatibility with existing hardware is maintained. The smooth inner bore located at each end of the permeate collection tube is unchanged, permitting insertion of sliding couplers and existing vessel adapters. The net length of the elements, when connected, remains 40 inches.
- Reduced permeate pressure drop – Internal couplers and vessel adapters account for more than 70 percent of the permeate-tube pressure drop in some systems. The interlocking endcap design minimizes these restrictions, imposing less permeate backpressure.
