8040 LG RO membrane Model: SW 400 R

1. What is the LG SW 400 R membrane?
The LG SW 400 R is an 8-inch seawater reverse osmosis (SWRO) membrane designed for seawater desalination applications. It combines high salt rejection, high permeate production, and long-term operating reliability.

2. What is the flow rate of the LG SW 400 R?
The LG SW 400 R has a nominal permeate flow rate of 9,000 GPD (34.1 m³/day) under the manufacturer's specified test conditions.

3. What is the salt rejection of LG SW 400 R?
The membrane provides 99.85% stabilized salt rejection and 99.7% minimum salt rejection under the specified test conditions.

4. What is the boron rejection of LG SW 400 R?
The LG SW 400 R has a 93% stabilized boron rejection under the manufacturer's specified test conditions.

5. What is the active membrane area of LG SW 400 R?
The LG SW 400 R has an active membrane area of 400 ft² (37 m²) and uses a 34-mil feed spacer.

6. Is LG SW 400 R suitable for seawater desalination?
Yes. LG Water Solutions lists the SW 400 R for single-pass and multi-pass seawater desalination RO system designs.

7. What are the test conditions for LG SW 400 R?
The published normalized performance is based on 32,000 ppm NaCl, 5 ppm boron, 800 psi (55.1 bar), 25°C, pH 8, and 8% recovery. Actual performance can vary depending on feed-water quality and operating conditions.

8. What is the maximum operating pressure of LG SW 400 R?
The maximum applied pressure specified by LG for the SW 400 R is 1,200 psi (82.7 bar).

9. What is the operating pH range of LG SW 400 R?
The continuous operating pH range is 2–11, while the cleaning pH range is 2–13, according to LG's product data sheet.

10. What makes LG SW 400 R suitable for industrial RO systems?
The membrane offers a combination of high salt rejection, seawater desalination capability, high permeate production, and boron rejection. Its thicker feed spacer is also designed to improve fouling resistance.

11. What is the difference between LG SW 400 R and LG SW 400 ES?
The LG SW 400 R is designed for higher salt and boron rejection, with 9,000 GPD flow and 99.85% stabilized salt rejection. The SW 400 ES has a lower nominal flow of 6,800 GPD and 99.6% stabilized salt rejection, so the appropriate model depends on the required water quality and system design.

12. Where can I buy LG SW 400 R in India?
The LG SW 400 R 8040 RO membrane is listed by Pearl Water Technologies, where the current product price and availability can be checked before purchase.
