For factory owners operating municipal tap water and shallow well raw water with TDS＜500ppm, the continuous high load of high-pressure pumps driven by ordinary Reverse Osmosis membrane brings a heavy monthly electricity burden. Conventional brackish Reverse Osmosis membrane element requires 150–225psi stable working pressure, while LF-XULP series energy-saving Reverse Osmosis membrane filter only operates under 100psi, greatly lowering the pressure bearing standard of pipelines and FRP vessels, and cutting the whole system’s power consumption by nearly one third. As a core energy-saving RO membrane for low-salinity water sources, this RO membrane element can form a complete two-stage filtration system when matched with PAN Ultrafiltration membrane module. The front UF membrane effectively intercepts colloids and suspended matter, stabilizes inlet SDI below 3, slows the fouling speed of RO membrane filter, and extends the overall service cycle of Reverse Osmosis membrane equipment by 2–3 times. All complete specifications of LF-XULP RO membrane and matched small-size UF membrane module are fully classified in our complete water filter element.
Main Industrial & Commercial Application Scenarios
1. Small and medium bottled mineral water, fruit beverage blending pure water production lines
2. Campus, office park and residential community centralized drinking water stations
3. Small pharmaceutical laboratory injection water pretreatment equipment
4. Rural underground low-salinity well water upgrading desalination project
5. Mini resort and hotel integrated domestic water purification unit
6. Light food factory low-tonnage process water treatment system
Exclusive Energy-Saving Advantages Of LF-XULP Reverse Osmosis Membrane
1. Ultra-low 100psi design pressure drastically reduces long-term power loss of the full Reverse Osmosis membrane system
2. Balanced high water flux and stable 98.5% minimum salt rejection for every single RO membrane element
3. Wide continuous operation pH range 3–10, compatible with daily online acid & alkali cleaning of RO membrane filter
4. Slow differential pressure rising trend after 24-hour nonstop operation, less forced equipment shutdown
5. Universal standard dimensions including 4021, 4040, 8040, direct drop-in replacement of international brand Reverse Osmosis membrane
6. Perfect supporting design with PAN Ultrafiltration membrane module to build full front pollution interception protection
