DUPONT FilmTec™ NF270-400/34i Element.Low Energy Nanofiltration Element for Organics and Hardness Removal.
Key Features:
• Provides high rejection of total organic carbon (TOC), trihalomethane (THM) precursors, and per- and polyfluoroalkyl substances (PFAS) while having medium to high salt passage and medium hardness passage.
• Provides partial softening to retain some hardness and alkalinity in the permeate to help manage corrosion risk in distribution systems.
• High rejection of multivalent ions at low feed pressure.
• Reduced energy consumption and enhanced fouling protection provided with 34 mil low differential pressure feed spacer.
• High productivity, low energy consumption element with effective cleanability due to its wide cleaning pH range (1 – 12) tolerance.
• Includes iLEC™ interlocking end caps, helping to reduce system operating costs and the risk of O-ring leaks that can cause poor water quality.
Key Applications:
Municipal Drinking Water
Wastewater Reuse
Typical Properties:
1. Permeate flow and salt rejection based on the following standard conditions: 2,000 ppm MgSO4, 70 psi (4.8 bar), 77°F (25°C) and 15% recovery.
2. LDP = Low Differential Pressure.
3. Flow rates for individual elements may vary but will be no more than 15% below the value shown.
4. Sales specifications may vary as design revisions take place.

Suggested Operating Conditions:
Important General Information:
• Keep elements moist at all times after initial wetting.
• For successful operation of Reverse Osmosis (RO) and Nanofiltration (NF) membrane systems, the operation must follow the guidelines provided in theFilmTec™ Reverse Osmosis / Nanofiltration Elements Operation Excellence and Limiting Conditions Tech Fact(Form No. 45-D04388-en).
• To prevent biological growth during prolonged system shutdowns, it is recommended that membrane elements be immersed in a preservative solution.
• The customer is fully responsible for the effects of incompatible chemicals and lubricants on elements.
• Avoid static permeate-side backpressure at all times.
• Permeate obtained from the first hour of operation should be discarded.
• The use of this product in and of itself does not necessarily guarantee the removal of cysts and pathogens from water. Effective cyst and pathogen reduction is dependent on the complete system design and on the operation and maintenance of the system.
