DOW FILMTEC™ SW30HRLE–400 Element
High Rejection, Seawater Reverse Osmosis Element
Description:
Dow Water & Process Solutions offers various premium seawater reverse osmosis (RO)
elements designed to reduce capital and operation cost of seawater RO systems.
DOW FILMTEC™ Elements combine premium membrane performance with automated
precision fabrication which takes system performance to exceptional levels.
DOW FILMTEC™ SW30HRLE–400 Elements offer a combination of high rejection and low
energy requirements to allow lower total costs with medium- and high-salinity feedwater.
Benefits of the DOW FILMTEC SW30HRLE–400 element include:
- Helps systems to be designed and operated to optimize operating cost through lower
energy consumption or to optimize capital cost through higher productivity at lower
operating fluxes.
- 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 posttreatments.
This is one reason 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
reducing the effect of overall fouling and maximizing element efficiency, helping to
lower your cost of operation.
Product Type Spiral-wound element with polyamide thin–film composite membrane.
Product Specifications:
1. The above values are normalized to the following conditions: 32,000 ppm NaCl, 5 ppm boron, 800 psi (5.5 MPa),77°F (25°C), pH 8, 8% recovery.
2. Permeate flows for individual elements may vary ± 15%.
3. Minimum Salt Rejection is 99.65%.
4. Stabilized salt rejection is generally achieved within 24 – 48 hours of continuous use; depending upon feedwater characteristics and operating conditions.
5. Product specifications may vary slightly as improvements are implemented.
6. Active area guaranteed ± 5%. Active area as stated by Dow Water & Process Solutions is not comparable to the nominal membrane area figure often stated by some element suppliers. Measurement method described in Form No. 609-00434.
