FilmTec™Element XC70 Element
Key Features:
• The ability to achieve reject Total Dissolved Solid (TDS) level >70,000 ppm.
• Robust, fouling resistant membrane enabling less cleaning, greate up-time and extended element life.
• Durable membrane that withstands cleaning over a wide pH range (from pH 1 to pH 13), ensuring a
long service life of and element and cost-effective maintenance.
Key Application:
• Industrial Minimum-and Zero-Liquid Dis charge (MLD/ZLD).
• Industrial wastewater recycling and reuse such as in textiles, steel & metals, chemicals &
petrochemical industries
