Filmtec SW30XLE-440i Element

  • $ 793.00

Dow® Filmtec™ SW30XLE-440i offers medium salinity and medium temperature feed waters an advanced combination of high productivity and high rejection through extra-low energy consumption and single-pass design. It is also an ideal choice for two- pass seawater designs or high salinity brackish water applications. The combination of high active area and thick feed spacer of the Dow Filmtec membranes results in higher productivity and lower cleaning frequency which enable sustainable lower lifecycle cost.
