VONTRON RO MEMBRANE LP21 – 4040
The LP is a low pressure series of aromatic polyamide compound membrane element.
It has the properties of low-pressure operation, high permeate flow and excellent desalination.
Being suitable for desalting such water sources as surface water (NaCl ≤10000ppm), undergroundwater, tap water and municipal water, etc., LP series is mainly applicable to treatment of various
industrial water such as industrial-purpose pure water, boiler water replenishment in power plants, and can be also applied to such brackish water applications, such as treatment of
high-concentration saline waste water and production of beverage-purpose water
