FilmTec membranes are high-performance Reverse Osmosis (RO) elements manufactured using Thin-Film Composite (TFC) technology. They are designed to remove dissolved salts, minerals, and impurities from water at the molecular level, producing clean, fresh, and safe water for human, commercial, and industrial use.
Developed by DuPont Water Solutions, FilmTec™ membranes are trusted globally for their efficiency, durability, and consistency in both small and large-scale water treatment systems.
How FilmTec™ Membranes Work
FilmTec™ membranes operate through the reverse osmosis process, where pressurized feed water passes through a semi-permeable polyamide layer.
This layer allows water molecules to pass while rejecting up to 99.5% of dissolved solids, including:
- Salts and minerals (TDS)
- Heavy metals such as lead and arsenic
- Organic contaminants and bacteria
- Nitrates and other harmful chemicals
The result is high-quality permeate (purified water) suitable for drinking, bottling, industrial processing, or laboratory applications.
Popular FilmTec™ Membrane Models and Sizes
FilmTec™ membranes come in various capacities and diameters, making them suitable for multiple system sizes and feedwater conditions. Tassmatt Limited supplies a wide range of models for domestic, commercial, and industrial systems:
| Model | Type | Capacity / Flow Rate | Typical Use |
| FilmTec™ TW30-1812-50 | Domestic RO | 50 GPD (Gallons Per Day) | Household RO systems |
| FilmTec™ TW30-1812-75 | Domestic RO | 75 GPD | High-output domestic units |
| FilmTec™ BW30-4040 | Brackish Water RO | 2400 GPD | Small commercial RO plants |
| FilmTec™ BW30-8040 | Industrial RO | 10,500 GPD | Large commercial & industrial systems |
| FilmTec™ SW30-4040 / SW30-8040 | Seawater RO | 8,000–24,000 GPD | Desalination plants |
Tip: The choice depends on your feedwater salinity (TDS), source (tap, borehole, or seawater), and daily water demand. Tassmatt experts help you select the right model for your system.

Maintenance & Care
To extend the life of your FilmTec™ membrane:
- Use prefilters and activated carbon filters for sediment and chlorine removal.
- Maintain SDI (Silt Density Index) ≤ 3 in feed water.
- Clean membranes periodically using approved RO cleaning chemicals.
- Replace membranes every 2–4 years, depending on use and feedwater quality.
Tassmatt Limited provides membrane replacement, cleaning chemicals, and after-sales support for all RO systems.
