WaterSolutions DOW FILMTEC SW30HR-380

The DOW™ 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 deslination systems.

DOW FILMTEC SW30HR-380 delivers high boron rejection to help customers meet World Health Organization (WHO) and other drinking water standards.
DOW 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 DOW 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.

Nominal Active Surface Area ft² (m²)	Permeate Flow Rate gpd (m³/d)	Stabilized Salt Rejection (%)	Minimum Salt Rejection (%)
380 (35)	6,000 (23)	99.7	99.6

Permeate flow rate and salt rejection based on the following test conditions: 32,000 mg/L NaCl, 800 psig (55 bar), 77°F (25°C), pH 8 and 8% recovery.
Permeate flow rates for individual elements may vary +/-15%.
Sales specifications may vary as design revisions take place.
Feed spacer is 28 mil.
