DOW FilmTec ECO Low Energy High Rejection Reverse Osmosis Elements

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

ECO elements reduce operating costs due to lower energy requirements Achieves reduction of the fouling impact by minimized pressure drop Delivers excellent silica, boron, nitrate, TOC and ammonium rejection Provides most effective cleaning performance, robustness and durability due to its widest cleaning pH range (1-13) and chemical tolerance. Elements with iLEC™ interlocking endcaps offer additional benefits:

• 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.
