Filmtec (TW30-4014) Tap Water Membrane 525 GPD @ 4"X14"
TW30-4014 Tap Water Membrane
525 GPD @ 4"×14"
High-rejection commercial RO membrane engineered for small-scale tap water purification systems requiring up to one gallon per minute of product water
Proven thin-film composite technology for consistent commercial performance
99.5% Salt Rejection
Stabilized rejection rate removes dissolved solids from tap water feeds, delivering consistent product water quality for commercial applications
525 GPD Output
Produces up to 1.99 m³/day at test conditions (2000 ppm NaCl, 225 psig, 77°F, 5% recovery), ideal for small commercial systems
Compact 4" × 14" Form
20 ft² of active membrane surface area in a space-efficient format fits tight installations without sacrificing filtration capacity
Low Energy Operation
Filmtec TW30 chemistry delivers industry-leading permeate flow at lower operating pressures, reducing energy costs over the membrane lifespan
Long Service Life
Durable composite construction withstands continuous operation in tap water applications, providing reliable performance and lower replacement frequency
Rated Performance
| Model Number | TW30-4014 |
| Dimensions | 4 inches × 14 inches |
| Active Surface Area | 20 ft² (1.9 m²) |
| Permeate Flow Rate | 525 GPD (1.99 m³/d) |
| Stabilized Salt Rejection | 99.5% |
| Test Conditions | 2000 ppm NaCl, 225 psig, 77°F, 5% recovery |
| Flow Variance | ±20% per element |
System Requirements
The Filmtec TW30-4014 membrane fits standard 4-inch diameter housings designed for 14-inch elements. Compatible with commercial reverse osmosis systems rated for tap water feed sources processing less than one gallon per minute of permeate. Requires 4" × 14" membrane housing with proper end caps and brine seal. Suitable for small commercial applications including food service, beverage preparation, laboratory use, and light industrial purification. Verify housing pressure rating matches or exceeds 225 psi operating pressure.
Replacement Schedule
Typical Membrane Life
Replace the TW30-4014 membrane when permeate flow drops below acceptable levels or salt rejection decreases. Actual lifespan depends on feed water quality, pretreatment effectiveness, and operating hours
Performance Monitoring
Track permeate TDS, flow rate, and feed pressure monthly to detect fouling or scaling. Early detection allows chemical cleaning before permanent damage occurs
Chemical Cleaning
Clean the membrane when normalized flow drops 10% or salt passage increases 10%. Follow Filmtec cleaning guidelines using approved chemicals for the specific foulant type
Pretreatment Maintenance
Maintain sediment filters and carbon pretreatment upstream of the membrane. Proper pretreatment protects the TW30-4014 from premature fouling and extends service life
Commercial Grade
Engineered for continuous-duty applications in demanding commercial environments
Proven Chemistry
Filmtec TW30 thin-film composite delivers consistent rejection across operating conditions
Lower Operating Cost
High flow at lower pressure reduces energy consumption and pump wear over time
Predictable Performance
Detailed specifications and test data enable accurate system design and performance modeling
