Features:

High rejection, esp. for SiO₂ rejection. BW Series Reverse Osmosis RO Membrane enable operational and maintenance cost saving of post-treatments equipment such as resin and EDI.
Consistent, outstanding performance, improved element structure, wide flow path and short membrane leaf design.BW Series HM RO Element elements stand for the super reliable operation and most effective cleaning.
Wide range and complete sets of products. There is 2.5 inch and 4.0 inch in diameter; 14 inch, 21 inch and 40 inch in length which can meet different system requirements about productive. Moreover, we can also design different size and specifications membrane elements according to client’s requirements.

Note： Test Conditions

Permeate flow and salt rejection based on the following test conditions: 2000 ppm NaCl, 225 psi (1.55Mpa), 77°F (25°C), pH 7.5, and above recovery.
Permeate flow rates for individual elements may vary +/-15%.
Minimum rejection is 99.0%.
