DuPont Water Solutions offers various premium seawater reverse osmosis (RO) elements designed to help reduce capital and operation cost of desalination systems. FilmTec™ elements combine excellent membrane quality with automated precision fabrication which takes system performance to exceptional levels.

FilmTec™ SW30XLE–440 Wet Elements offer medium-salinity and medium-temperature feedwaters an advanced combination of high productivity and high rejection through extra-low energy consumption and single-pass design. It is also an excellent choice for two-pass seawater designs or high salinity brackish water applications. The combination of high active area and thick feed spacer facilitates high productivity and low cleaning frequency, which enables sustainable low life-cycle cost. Benefits of the FilmTec™ SW30XLE–440 Wet Elements include:

• High active area of 440 ft² (41 m²) permits low system capital cost by maximizing productivity and enables accurate and predictable system design and operating flux
• The combination of high active area with thick feed spacer (28 mil) allows low cleaning frequency and high cleaning efficiency
• Sustainable high performance over the operating lifetime, because oxidative treatments are not used in membrane production. This is one reason FilmTec™ elements are more durable and may be cleaned more effectively over a wider pH range (1 – 13) than most other RO elements, which use oxidative treatments.
• Effective use in permeate staged seawater desalination systems without impairing the performance of the downstream stage
