Produkt-Beschreibung

Product Description:

For more accurate membrane product selection and performance prediction, it is essential for customers to conduct at least one comprehensive chemical analysis of the feed water. Ideally, multiple rounds of water composition analysis should be performed over an extended period, especially in cases where abrupt changes in water quality are likely. Historical trends in membrane system performance parameters are highly valuable, particularly for surface water sources, which may exhibit seasonal variations due to events such as spring runoff or lake/pond turnover. Frequent changes—including heavy rainfall or even wind, which can stir up sediments in lakes or ponds—may affect surface water quality and lead to fluctuations in feed turbidity. In general, the more existing and historical data available for analysis, the better the overall system design can be optimized.



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.
