Filmtec (TW30-4021) Tap Water Membrane 900 GPD @ 4"X21"
TW30-4021 Tap Water Membrane 900 GPD
The Filmtec TW30-4021 is engineered for small commercial reverse osmosis systems purifying less than one gallon per minute. With 36 ft² of active membrane surface area and 99.5% stabilized salt rejection, this membrane delivers consistent performance at 900 GPD nominal flow when processing standard tap water sources.
Built for Commercial Tap Water Purification
High Permeate Flow
900 GPD nominal flow rate tested at 2000 ppm NaCl, 225 psi, 77°F, 8% recovery conditions
Superior Salt Rejection
99.5% stabilized salt rejection delivers consistently high-quality permeate for commercial applications
Compact 4"×21" Design
Standard 4-inch diameter, 21-inch length fits small commercial housings with 36 ft² active surface area
Low Energy Operation
Optimized for tap water feedstreams, delivering lowest energy costs in its class
Long Service Life
Filmtec's proven thin-film composite construction provides industry-leading reliability and performance
Application-Specific
Designed specifically for tap water sources in systems producing less than one gallon per minute
Small Commercial RO Systems
The Filmtec TW30-4021 membrane is designed for small commercial reverse osmosis systems processing municipal tap water or similar low-TDS sources. Compatible with standard 4-inch membrane housings rated for 21-inch elements. Ideal for restaurants, laboratories, small manufacturing facilities, beverage preparation, and point-of-use commercial water purification where permeate demand is under 1 GPM. Individual element performance may vary ±20% from nominal specifications.
Filmtec membranes have set the standard for commercial reverse osmosis performance for decades, delivering the highest quality permeate water with the longest service life in the industry.
