Many medium and small pure water manufacturers are plagued by high power consumption of traditional brackish water reverse osmosis systems. Conventional BW series RO membrane requires 225psi standard operating pressure, which leads to high load of high-pressure pumps and brings continuous high electricity bills every month. Our independent developed LF-XULP series ultra-low pressure RO membrane only needs 100psi driving pressure to reach stable water yield and desalination efficiency, which can reduce the power consumption of the whole system by nearly 30% under the premise of ensuring water quality stability. This series adopts optimized aromatic polyamide TFC composite separation layer, the surface is modified with hydrophilic coating, which effectively inhibits slight scaling of tap water and low-salinity groundwater, and the daily maintenance cycle is greatly prolonged.
All specifications of LF-XULP RO membrane and matched PVDF UF membrane pretreatment modules are fully classified in our complete water filter element series.
Main Industrial Application Fields
1. Food & beverage factory bottled pure water and fruit juice blending water preparation
2. Community, office and campus centralized domestic purified water equipment
3. Small pharmaceutical factory laboratory injection purified water system
4. Rural low TDS underground well water desalination upgrading project
5. Electronic workshop small-scale cleaning pure water pretreatment line
6. Hotel and resort central water purification unit with low hourly water volume
Core Performance Advantages of LF-XULP RO Membrane
1. Ultra-low 100psi test pressure design, no need to configure high-power high-pressure pump
2. Stable salt rejection rate up to 98.5%, minimum desalination rate reaches 97.0
3. Large single element water production, LF-XULP-8040 can produce 39.7 cubic meters per day
4. Wide continuous operation pH range of 3-10, adapt to regular acid and alkali online cleaning
5. Low differential pressure attenuation after long-term continuous operation, no frequent shutdown cleaning
6. Standard 4021 / 4040 / 8040 universal size, directly replace old brand low-pressure RO elements without equipment transformation

LF-XULP-4021, LF-XULP-4040, LF-XULP-8040, LF-XULP-8040-440
In actual project matching, it is recommended to install external pressure PVDF UF membrane as front pretreatment, cooperate with 5μm large-flow security filter cartridges to intercept suspended particles and colloids in raw water, stabilize inlet SDI value below 3, and further extend the service life of XULP RO membrane elements. Our technical team can provide free raw water quality matching scheme according to customer water volume and TDS test data.
