Description
DuPont FilmTec SW30XHR-440i membrane offers the highest salt rejection among all seawater RO elements in the FilmTec range, making it highly effective for meeting demanding water quality standards with single-pass systems in most applications. Its large active membrane area and thick feed spacer enhance productivity while minimizing the need for frequent cleaning, supporting long-term operational efficiency and reduced lifecycle costs. Additionally, the integrated iLEC™ Interlocking End-caps help lower operating costs and minimize the risk of O-ring leaks, ensuring consistent water quality.
Key Features
- Excellent choice for the most stringent permeate water quality requirements.
- Permits low system capital cost by maximizing production capacity.
- Excellent durability resulting in stable long-term performance.
- Includes iLEC™ interlocking end caps, reducing system operating costs and the risk of o-ring leaks that can cause poor water quality.
