Membrane Parameters
| Product | Part number | Active Area ft2(M2) | Feed Spacer Thickness (mil) | Permeate flow rate gpd (m3/d) | Stabilized salt rejection (%) | Minimum salt rejection (%) |
| BW30-365 | 80773 | 365 (34) | 34 | 9,500 (36) | 99.5% | 99.0% |
| BW30-400 | 98650 | 400 (37) | 28 | 10,500 (40) | 99.5% | 99.0% |
Same point: Salt rejection rate is the same 99.5%
Difference:
BW30-365
- Feed spacer thickness is larger, which can lessen the impact of fouling.
- Suitable for systems operating on challenging feed streams, where reliable pretreatment is not an option, or where maximum cleanability delivers value.
- Membrane price lower, which can save replacing cost.
BW30-400
- Feed spacer thickness is smaller, so compare with BW30-365, it more like to fouling and high rejection. This model will be choose when highest quality permeate is required.
- The active area and permeate flow is larger, which can deliver high flow.
- Membrane price high. High initial investment and consumable replacement costs.
