FilmTec™ Seamaxx™-440 Wet

About this product

DuPont Water Solutions offers various premium seawater reverse osmosis (SWRO) elements designed to reduce capital and operation cost of desalination systems. FilmTec™ elements combine premium membrane quality with automated precision fabrication resulting in outstanding performance, reliability and robustness. Wet FilmTec™ Seamaxx™-440 elements are the choice for seawater systems operating at low to medium levels of salinity and temperature, as well as for brackish water with relatively high salinity. The element’s flowrate is significantly above flowrates of any other SWRO element currently available in the market. This extraordinary high element productivity leads to substantial savings, primarily in energy consumption when compared to conventional low-energy SWRO products. In addition, FilmTec™ Seamaxx™-440 includes the typical FilmTec™ element features: - The 28-mil feed spacer combines low differential pressure with low cleaning frequency and high cleaning efficiency. - The oxidative-free membrane manufacturing process results in high membrane robustness and long-term stable performance. - The widest pH range for cleanings (pH 1 – 13) allows effective cleanings even in cases of severe fouling. - The automated, precision fabrication gives a greater number of shorter membrane leaves thus reducing fouling while maximizing element efficiency. Uses Seawater desalination for municipal and industrial applications Suitable for low and medium feed water salinity Applicable for optimized Internally Staged Designs (ISD) in combination with other seawater FilmTec™ membranes Direct lithium extraction Advantages Delivers very high permeate flow allowing considerable savings in energy consumption Permits low system capital cost by maximizing production capacity Excellent durability resulting in stable, long-term performance Suitable for mid-stage lithium concentration in Direct Lithium Extraction (5–10x enrichment)
