Many small and medium pure water manufacturers face long-term high power expenditure from traditional low-pressure RO membrane systems. Conventional BW reverse osmosis elements require 225psi steady operating pressure, which puts heavy load on high-pressure pumps and generates continuous monthly electricity costs. Our independently developed LF-XULP ultra low pressure RO membrane adopts optimized aromatic polyamide TFC composite separation layer, which can reach standard stable water yield and 98.5% average salt rejection under only 100psi test pressure. It reduces the overall energy consumption of the whole water station by nearly 30%, and lowers the pressure bearing standard of pipelines and pressure vessels to cut equipment procurement cost simultaneously.
This series is specially designed for raw water with TDS below 500ppm, such as tap water, surface water and rural shallow well water. When matched with PAN internal pressure UF membrane as front pretreatment, it can stabilize inlet SDI below 3, eliminate frequent RO fouling and extend the service cycle of membrane elements significantly. All XULP series elements and supporting ultrafiltration modules are integrated in our complete water filter element series.
Main Industrial Application Scenarios
1. Small bottled mineral water factory production water equipment
2. Community, campus and office building centralized purified water station
3. Food processing plant fruit juice blending process water line
4. Small laboratory and medical clinic purified water unit
5. Rural underground low-salinity well water upgrading project
6. Small hotel integrated domestic water treatment system
Core Performance Advantages of LF-XULP RO Membrane
1. Ultra-low 100psi design pressure, no need to configure high-power high-pressure pump
2. Stable average salt rejection up to 98.5%, minimum desalination rate reaches 97.0%
3. Large single-element daily water output up to 47.3 cubic meters for LF-XULP-8040-440
4. Wide continuous operation pH range 3-10, adapt to routine acid & alkali online cleaning
5. Low long-term differential pressure attenuation, less frequent shutdown maintenance
6. Universal 40/80 inch standard size, direct replacement of mainstream foreign brands without equipment reconstruction
