LF‑ULP‑4040‑D Low‑Energy RO Membrane Element For Medium Factory Pure‑Water Line

Medium‑size manufacturing factories pursue balanced water‑yield and desalination performance. Our Oil Filtration Machine matched LF‑ULP‑4040‑D RO membrane element solves the contradiction of ordinary RO membrane: either energy‑saving but low salt‑rejection, or high‑precision with high pump‑cost. LEFILTER LF‑ULP‑4040‑D optimized RO membrane filter works under 1.03 MPa pressure and reaches salt‑rejection up to 99.5%. This balanced‑performance Reverse Osmosis membrane is mainstream industrial desalination consumable and needs large‑flow UF membrane module as pre‑treatment. Browse complete water‑treatment series via Water Filter Element. Security filtration chooses High Flow Filter Cartridge.

Balanced‑Performance Principle Of LF‑ULP‑4040‑D RO Membrane Element

Medium‑concentration brackish‑water flows tangentially over LF‑ULP‑4040‑D RO membrane surface under moderate driving pressure. Modified composite polyamide layer of this Reverse Osmosis membrane realizes both high water permeability and dense salt‑interception structure. Dissolved‑salts, silicon‑dioxide and macromolecular organics are trapped on RO membrane filter surface. Permeate clean water flows to central collection tube for industrial production usage. Moderate‑roughness surface of Reverse Osmosis membrane element reduces scaling and organic‑adsorption risk and lowers daily maintenance workload.

Core Technical Parameters

• Membrane Material: Balanced‑flux composite polyamide for RO membrane filter

• Stable Salt Rejection of Reverse Osmosis membrane: 99.3%‑99.5%

• Standard Test Pressure of RO membrane element:1.03 MPa (150psi)

• Applicable Raw‑Water TDS: ≤1500 ppm brackish‑water for RO membrane

• Matching Pre‑Treatment: Large‑flux UF membrane module

Every LF‑ULP‑4040‑D Reverse Osmosis membrane element passes dual inspection for flux and salt‑rejection before shipment; compatible with industrial pressure vessels supporting High Flow Filter Cartridge.
