LF-ULP Ultra Low Energy RO Membrane Element For Medium Factory Pure Water Line

Medium-sized manufacturing factories need to balance water yield and desalination rate, many ordinary RO membrane either save power but low salt rejection, or high precision with high pump cost. LEFILIER LF-ULP low energy RO membrane is optimized RO membrane element to solve this contradiction, this balanced polyamide RO membrane filter runs under 1.03MPa pressure, salt rejection up to 99.5%, perfectly compromise energy consumption and water quality compared with common Reverse Osmosis membrane. As mainstream medium-scale industrial desalination consumable, LF-ULP Reverse Osmosis membrane element matches large-flow UF membrane module as pretreatment to extend the service life of RO membrane filter. Our company owns complete independent membrane production line and full set testing equipment, all LF-ULP RO membrane pass 1000-hour aging inspection, all water treatment products unified at Water Filter Element category, oil and gas gas filter series at gas filter element.

Balanced Performance Principle Of LF-ULP RO Membrane Element

Medium-concentration brackish water flows across LF-ULP RO membrane under moderate driving pressure. The composite modified polyamide film of this Reverse Osmosis membrane achieves both high water permeability and dense salt interception structure, soluble salts, silicon dioxide and organic impurities are trapped on RO membrane filter surface, clean permeate water flows into central tube for industrial production use. The balanced surface roughness design of Reverse Osmosis membrane element avoids excessive scaling and organic adhesion, greatly reduce factory daily maintenance work of RO membrane.

Core Technical Parameters

• Membrane Material: Balanced flux polyamide for RO membrane filter

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

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

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

• Matching Pre-Treatment: Large flux UF membrane module

Every LF-ULP Reverse Osmosis membrane element undergoes flux and desalination dual testing, compatible with standard industrial pressure vessels supporting High Flow Filter.
