LG SW 400 R membrane, 8×40″ seawater reverse osmosis membrane

Description

LG seawater reverse osmosis membranes: LG SW 400 R, 8″×40″.

LG SW 400 R 8″×40″ seawater membranes represent an advanced solution in seawater desalination. Designed with the latest reverse osmosis membrane technology, these membranes are ideal for applications where superior performance and high reliability are required in the production of potable water from saltwater.

LG Chem’s NanoH₂O™ seawater reverse osmosis membranes, which integrate innovative thin film nanocomposite (TFN) membrane technology, lower desalination costs while providing superior water quality. The seawater membranes offer industry-leading salt rejection and 20% higher production capacity than conventional technologies. We leverage the technical advantages of our seawater reverse osmosis membranes to expand our market share, achieving an output of more than 3 billion liters per day (MLD) in new projects and replacements since our founding.

Benefits of LG SW 400 R membrane

1. Maximum salt rejection efficiency: LG SW 400 R membranes provide up to 99.89% salt rejection, guaranteeing high quality drinking water.
2. High permeate flux: With a permeate flux of 7,500 GPD, these membranes allow a constant and abundant water production, ideal for large installations.
3. Robust and durable design: Its construction is designed to withstand the harsh conditions of seawater desalination, ensuring a long service life.
4. Lower energy consumption: Thanks to their efficient design, these membranes operate at a relatively low pressure compared to others on the market, reducing energy consumption.
5. Advanced anti-fouling properties: Incorporate materials that minimize fouling, reducing maintenance costs and extending intervals between cleanings.
6. Compatibility and versatility: They are easily integrated into various configurations of reverse osmosis systems, adapting to the specific needs of each plant.

Comparison with competing membranes

LG SW 400 R membranes outperform Hydranautics SWC5-LD 8×40″ membranes in several key respects:

• Higher salt rejection: While the Hydranautics SWC5-LD achieves 99.8% salt rejection, the LG SW 400 R achieves 99.89%, ensuring higher purity of produced water.
• Better energy efficiency: They operate at a pressure of 800 psi, which is lower than the pressure required by many competing membranes, resulting in lower energy consumption.
• Superior durability: LG’s thin film nanocomposite (TFN) technology ensures greater resistance to fouling and harsh operating conditions, providing longer life and more reliable operation.
