The FILMTEC SW30HR-380 is a premium grade seawater reverse osmosis element featuring both high active area and high salt rejection to offer the best long-term economics for seawater desalination systems.FILMTEC SW30HR-380 delivers the highest boron rejection to help customers meet World Health Organization (WHO) and other drinking water standards.FILMTEC SW30HR-380 elements deliver high performance over their operating lifetime without the use of oxidative post-treatments like many competitive products. This is one reason why FILMTEC elements are more durable and may be cleaned more effectively over a wider pH range (1-13) than other RO elements.Automated, precision fabrication with a greater number of shorter membrane leaves, reduces the overall effect of fouling and maximizes membrane efficiency.
