Description
FilmTec™ SW30HRLE-370/34i Elements are durable, high-rejection, high-productivity seawater elements for use in high-fouling or challenging feedwater conditions, helping to support smooth operations and low cost of water.
Benefits of the FilmTec™ SW30HRLE-370/34i Element include:
- A wide 34-mil feed spacer to lessen the impact of fouling on pressure drop across a vessel and enhance cleaning effectiveness.
- An active area of 370 ft2, maximizing productivity and enabling accurate and predictable system design and operating flux.
- Utilization of the distinct iLEC™ Interlocking Endcaps that help to reduce system operating costs and reduce the risk of O-ring leaks that cause poor water quality.
- Effective use in permeate-staged seawater desalination systems without impairing the performance of the downstream stage.
- High performance over the operating lifetime without the use of oxidative posttreatments. FilmTec™ Elements are more durable and may be cleaned over a wider pH range (1 – 13).
- Automated, precision fabrication with a greater number of shorter membrane leaves reducing the effect of overall fouling and maximizing element efficiency.
Starting in 2020, DuPont Water Solutions has produced and supplied our customers dry seawater reverse osmosis FilmTec™ elements. As an industry leader, we will be the first supplier to offer dry-tested SWRO elements.
- Dry elements do not have expiration date, making easier warehouse maintenance and inventory planning.
- Dry elements do not need re-preservation while wet elements preservation solution needs to be checked after 12 months of storage and eventually replaced. This operation is very labor intensive and can lead to high costs.
- More attractive warranties. The allowable storage time before mandatory start of the warranty has been extended by 6 months.
- Dry elements are lighter (4 kg / 8 pounds less) and do not have a preservation solution, which involves an easier and safer loading and installation.
- Due to the lower weight and the lower energy and water consumed during testing, dry elements are more environmentally friendly compared to wet elements, more specifically dry elements represent a 20% reduction in CO2 emissions compared to wet elements.
