Filmtec™ BW30 Pro-2540 "Brackish Water" RO Membrane
The Filmtec™ BW30 PRO-2540 RO Membrane are fiberglassed Large Commercial Elements designed for challenging Water Conditions.
A Reverse Osmosis (RO) Membrane forms the heart of a Reverse Osmosis System. It consists of a semi-permeable membrane that allows water molecules to pass through but captures 99.8% of all other particles in the water. The RO Membrane removes bacteria, viruses, minerals, heavy metals, and pesticides from the water.
The BW30 Pro-2540 RO Membranes are designed to handle high mineral content source water for medium-sized commercial or industrial applications, such as DI (Deionized) water, Laboratories, Hospitals, Battery water, aquariums, offices, ice makers, restaurants, etc. The BW30 Pro-2540 membranes are rated to handle source waters that have a TDS of 10 000ppm or lower (<10 000ppm).
FilmTec™ BW30 Pro-2540 size Elements features:
- FilmTec™ membrane is an industry standard for reliable operation and production of high-quality water.
- FilmTec™ BW30 Pro-2540 Elements are designed for systems smaller than 1 gpm (0.2 m3/h) offering a hardshell exterior for extra strength.
- NSF safety certification and the ability for NSF data transfer reduce certification costs
- Delivers consistent water quality and higher rejection and flow than previous generation FilmTec™ BW30 product.
- Based on historical FilmTec™ BW30 industry-standard RO membrane with decades of proven performance.
- Outstanding durability resulting in stable, long-term performance and sustainable water solutions.
- Enhanced fouling protection.
- Dry elements achieve quick stabilization.

Keep in Mind
The average permeated (product) water flow is based on test water consisting of 32000ppm of only salt (NaCl) which is one of the easier minerals for the RO membrane to handle. Other elements such as hardness (lime, Calcium/Magnesium) are harder for the membranes to remove, and may reduce the average permeate rate of the RO membrane.
Other elements such as source water pressure and the Total Dissolved Solids (TDS / Total Mineral Content) level can also have an influence on the permeate level produced by the membrane. Typically in real-world situations with municipal or non-municipal source water quality, you will not get the same quality and/or pressure as the "testing conditions" used to rate the membranes. So, in most applications, you will likely find that the actual permeate flow rate of the RO membrane is between 30 to 80% of what has been rated.
