DOW FILMTEC™ Nanofiltration 8" Elements

DOW FILMTEC™ Nanofiltration 8" Elements allow selective separation of organics and salts for large-scale industrial and municipal water treatment plants that produce greater than approximately 10 gpm (2300 L/h) of permeate.

DOW FILMTEC™ NF270-400/34i

DOW FILMTEC™ NF270-400/34i Elements are ideal for utility managers and operators dealing with surface and groundwater and seeking a technology that removes a high percentage of total organic carbon (TOC) and trihalomethane (THM) precursors while having a medium to high salt passage and medium hardness passage.

Used In:

  • Production of municipal drinking water


  • Provides organic removal with partial softening in order to maintain a minimum level of hardness for organoleptic properties and preservation of distribution networks
  • Delivers high productivity, cleanability and low energy consumption due to its high active area and wide cleaning pH range (1 – 12) tolerance
  • Includes iLEC™ interlocking end caps, reducing system operating costs and the risk of o-ring leaks that can cause poor water quality
