LF-XULP Ultra Low Pressure RO Membrane Element For Small Drinking Water Station

Small water station operators always face high daily electricity cost caused by ordinary RO membrane. Conventional Reverse Osmosis membrane element requires high driving pressure, which brings long-term high power consumption of water pump. LEFILIER LF-XULP ultra low pressure RO membrane is a cost-saving RO membrane element developed for light TDS tap water, this thin high-permeability RO membrane filter can reach stable water yield only under 0.69MPa pressure, 40% energy saving

 compared with standard Reverse Osmosis membrane. As core desalination consumable for small-scale water equipment, LF-XULP Reverse Osmosis membrane element must match standard UF membrane module as front pretreatment to reduce fouling speed of RO membrane filter. Our factory is a listed high-tech enterprise with complete membrane production testing equipment, all LF-XULP RO membrane pass long-term aging test before delivery, you can browse all water treatment parts via Water Filter Element, oil & gas filtration coalescer cartridge can be viewed on gas filter element.

Energy-Saving Working Principle Of LF-XULP RO Membrane Element

Low TDS municipal tap water flows tangentially over LF-XULP RO membrane surface under ultra-low driving pressure. The ultra-thin hydrophilic polyamide layer of this Reverse Osmosis membrane greatly improves water molecule penetration efficiency, salt ions, heavy metals and colloids are fully intercepted on the surface of RO membrane filter and discharged with concentrated water. The smooth surface design of Reverse Osmosis membrane element reduces organic adhesion, extend the chemical cleaning cycle of RO membrane, effectively lower the operation cost of small drinking water stations all year round.

Core Technical Parameters

• Membrane Material: Ultra-thin high-flux polyamide for RO membrane filter

FAQ About LF-XULP RO Membrane

Q1 What raw water fits LF-XULP RO membrane filter?
A1 Tap water with TDS below 500ppm, not for high-salinity seawater Reverse Osmosis membrane element.

Q2 Is UF membrane module required before this RO membrane?
A2 Yes, Ultrafiltration membrane intercept colloids to protect Reverse Osmosis membrane from fast fouling.

Q3 What is the test pressure of LF-XULP RO membrane element?
A1 Standard operating pressure only 0.69MPa, much lower than ordinary RO membrane filter.

Q4 Can LF-XULP replace ordinary 4040 Reverse Osmosis membrane directly?
A4 Same outer dimension, direct installation into standard pressure vessels without modification.
