    BW30-2540 "Brackish Water" RO Membrane

    The 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 BW30-2540 RO Membranes are designed to handle high mineral content source water for medium size commercial or industrial applications, such as DI (Deionized) water, Laboratories, Hospitals, Battery water, aquariums, offices, ice makers, restaurants, etc. The BW30-2540 membranes are rated to handle source waters that have a TDS of 10 000ppm or lower (<10 000ppm).

     

    FilmTec 2540 size Elements features:

    • FilmTec™ membrane is an industry standard for reliable operation and production of high-quality water.
    • FilmTec™ BW30-2540 Elements are designed for systems smaller than 1 gpm (0.2 m3/h) offering a hardshell exterior for extra strength.
    • Longer lifetimes can reduce operating costs for OEM’s/brand owners
    • NSF safety certification and the ability for NSF data transfer reduce certification costs
    • Fully-automated manufacturing that ensures consistent and high-quality elements
    • Dry shipping for convenient handling and longer shelf-life
    • High-quality elements significantly reduce or eliminate element Quality Control (QC) costs

    FilmTec Membranes are FDA Compliant    FilmTec Membranes are NSF Certified  Genuine DOW FilmTec Membrane Element   DOW FilmTec Home RO Membranes are Made in USA

    Testing Conditions for Specification rating: 

    Testing Pressure: 225psi (15.5 bar) 

    Testing Solution Temperature: 25°C

    PH Value of Testing Solution: 6.5 - 8.5

    Recovery Rate of Single Element: 15%

     

    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.
