Filmtec (SW30-2540) Seawater Membrane 700 GPD 2.5"X40"
Filmtec SW30-2540 Seawater RO Membrane
Engineered for High-Salinity Desalination
Seawater-Grade Rejection
Filmtec SW30 membrane delivers 99.4% salt rejection at 32,000 ppm feed concentration, purpose-built for marine and coastal desalination applications.
High Flow at 800 PSI
Produces 700 gallons per day at 800 PSI operating pressure with 29 sq ft active membrane surface area, or run at lower pressure to reduce pump costs.
Precision Fabrication
Automated manufacturing ensures consistent performance element to element. Individual flow rates may vary ±20% within spec tolerance.
2.5" Commercial Size
Standard 2.5" × 40" footprint fits commercial seawater RO housings for both land-based and sea-based desalination systems.
Optimized for 2% Recovery
Test conditions specify 2% recovery at 77°F, ideal for single-pass seawater applications where concentrate management is critical.
Standard Commercial Seawater Housings
The Filmtec SW30-2540 membrane fits any commercial RO housing designed for 2.5" diameter × 40" length membrane elements. Compatible with seawater desalination systems operating at 800 PSI with 32,000 ppm NaCl feedwater. Verify housing pressure rating and end cap compatibility before installation. Suitable for land-based municipal desalination plants, offshore platforms, marine vessels, and coastal brackish water treatment where elevated TDS requires high-pressure operation.
Membrane Replacement Schedule
Membrane Replacement
Replace Filmtec SW30-2540 element when permeate flow drops 15% or salt passage increases 15% from baseline, typically 3–5 years depending on feedwater quality and cleaning frequency.
Chemical Cleaning
Clean membrane with approved low-pH and high-pH solutions when normalized pressure drop increases 15% or normalized salt passage rises 5–10%. Proper cleaning extends membrane life.
Performance Monitoring
Log permeate flow, conductivity, and pressure drop monthly. Normalize data to standard conditions to track membrane degradation and schedule cleaning before fouling becomes irreversible.
Upstream Filtration
Install 5-micron sediment pre-filter and check cartridge fouling before seawater reaches membrane. Proper pre-treatment prevents particulate damage and extends SW30-2540 service life.
Industry-Leading Flow
Highest GPD available in 2.5" seawater membranes for maximum desalination capacity per housing footprint.
Lower Operating Cost
Option to reduce operating pressure below 800 PSI cuts pump energy consumption while maintaining commercial flow rates.
Proven Technology
Filmtec SW30 chemistry trusted worldwide in marine and municipal desalination for consistent 99.4% salt rejection.
Drop-In Replacement
Standard 2.5" × 40" dimensions fit existing commercial seawater RO housings without modification or custom fittings.
