FilmTec™ ECO-400i

DOW FILMTEC ECO-400i Elements offer unparalleled rejection and flow performance for your industrial water needs, enabling lower energy usage and reduced regeneration costs in downstream polishing units. With a new industry-leading performance of 99.7% rejection at 150 psi, DOW FILMTEC ECO elements provide robust performance over a longer element life. Compared to standard RO elements, DOW FILMTEC ECO-440i elements can deliver up to 40% lower salt passage at 30% less energy—an ecological and economical win. iLEC™ Interlocking End Caps reduce system operating costs and the risk of o-ring leaks that can cause poor water quality.

a. Maximum temperature for continuous operation above pH 10 is 95°F (35°C).
b. Refer to Cleaning Guidelines in specification sheet 609-23010.
c. Under certain conditions, the presence of free chlorine and other oxidizing agents will cause premature membrane failure. Since oxidation damage is not covered under warranty, it is recommended that residual free chlorine be removed by pretreatment prior to membrane exposure.
