LG BW 4040 ES, 4×40″ low pressure reverse osmosis membranes

Description

LG BW 4040 ES membrane, 4×40″ low pressure reverse osmosis membrane

LG BW 4040 ES 4″×40″ reverse osmosis membranes represent an advanced and efficient solution for brackish water filtration. Designed specifically for low pressure operation, these membranes feature superior performance and durability, making them ideal for demanding industrial applications. LG Chem’s NanoH₂O™ brackish water reverse osmosis membranes are widely used in municipal and industrial applications, being operational in major plants worldwide. Thanks to innovative nanocomposite thin film technology (TFN), all LG BWRO membranes offer superior performance and anti-fouling properties, making them ideal for applications requiring consistent and reliable performance.

Benefits of the LG BW 4040 ES Membrane

1. High energy efficiency: LG BW 4040 ES membranes require lower operating pressure, which significantly reduces energy consumption.
2. High salt rejection: With a salt rejection rate of 99.6%, these membranes ensure the production of high purity water.
3. Long service life: Robust design and high quality materials ensure long and consistent performance.
4. Compatibility and versatility: They easily adapt to various configurations of reverse osmosis systems, facilitating their integration into different industrial environments.
5. Low maintenance: Lower incidence of fouling and easy cleaning reduces downtime and operating costs.

Superiority over the competition

LG BW 4040 ES membranes outperform competing options, such as the Hydranautics ESPA1-4040, ESPA2-LD 4040 and ESPA4 4040, in several key respects:

• Operating efficiency: They require an operating pressure of only 150 psi, compared to the higher pressure demands of Hydranautics membranes, which translates into lower energy consumption.
• Salt rejection: They offer superior salt rejection, reaching 99.6%, compared to the lower figures of some competing models.
• Durability and maintenance: LG’s advanced nanotechnology minimizes fouling and extends membrane life, exceeding the durability of Hydranautics models.
