FILMTEC SW30ULE-400i Membrane Elements
Features
Dow Water Solutions offers various premium seawater Reverse Osmosis (RO) elements which combine premium membrane performance with automated precision fabrication and maximize system output to unprecendented performance. FILMTEC™ SW30ULE-400i is an element with one of the highest flow rates in the industry, and high rejection of NaCl and boron. This performance can lead to significant capital and operation cost savings, especially when this element is mixed with other element types in the same pressure vessel, using the “internally staged design” approach. The benefits of the FILMTEC SW30ULE-400i elements include:
- One of the highest seawater element flow rate in the industry. This may lead to lower capital and operation cost in a seawater system.
- High NaCl and Boron rejection to help meet World Health Organization (WHO) and other drinking water standards.
- 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 post-treatments.
- Automated, precision fabrication with a greater number of shorter membrane leaves reduces the effect of overall fouling and maximizes element efficiency.
