    "Experience Unmatched Efficiency with Our High-Performance Membrane Bioreactor for Reverse Osmosis

    Product Description:

    To ensure accurate membrane product selection and performance prediction, customers should conduct at least one comprehensive chemical analysis of the feed water. Ideally, multiple analyses should be performed over an extended period or during potential abrupt changes in water quality. Historical trends in membrane system performance parameters are crucial, particularly for surface water sources, which may exhibit seasonal variations due to spring runoff or lake/pond turnover events. Frequent changes, such as heavy rainfall or even wind—which can stir up sediments in lakes or ponds—affect surface water composition and lead to fluctuations in feed turbidity. Generally, the more existing and historical data analyzed, the better the overall system design.


    For example:

    Surface water may contain suspended solids, organic matter, and various microorganisms;

    Well water might include scaling substances such as hardness and silica;

    Municipal water sourced from surface supplies could contain residual chemicals from treatment processes, including aluminum and iron, which may deposit on membranes in the form of hydroxides or silicates;

    Recycled industrial wastewater may introduce various contaminants, scaling components, and membrane-damaging compounds such as oils, surfactants, and defoamers.



    Operating and Cleaning Limits:
    1. Flow rate and salt rejection are based on the following test conditions: 1500 ppm NaCl solution, 77ºF (25ºC), pH: 7.5, 15% recovery rate, and the rated applied test pressure mentioned above.
    2. The minimum salt rejection rate is 99.0%.
    3. The flow rate of a single element may vary within a range of ±15%.

    Maximum Operating Temperature: 113 °F (45 °C)
    Maximum Operating Pressure: 600 psi (4.14 MPa)
    pH Range, Continuous Operation: 3-10
    Maximum Feed Silt Density Index (SDI): < 5
    Maximum Feed Flow Rate: 16 gpm (3.6 m³/h)
    Chlorine Tolerance: < 0.1 ppm

    Notes:
    a. The maximum temperature for continuous operation at pH above 10 is 95 °F (35 °C).
    b. Under certain conditions, free chlorine and other oxidizing agents may cause premature membrane failure. Since damage from oxidation is not covered under warranty, it is recommended that customers remove residual chlorine through pretreatment prior to membrane contact.
