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.
