Many engineering purchasers blindly select single RO membrane without matching corresponding UF membrane according to raw water test data, resulting in frequent blockage, unstable water conductivity and extremely high annual operation cost. The collocation of ultrafiltration and reverse osmosis must be judged by three core indicators: raw water TDS salinity, COD organic content and turbidity value. This article combines all LF series membrane parameters in our product catalog to sort classified matching schemes for six mainstream water source types, helping buyers avoid wrong model procurement losses and realize long-term low-cost stable operation of dual-membrane water treatment equipment.
1.Low-salinity tap water (TDS<500ppm): LF-XULP RO + small PAN internal pressure UF
2.Medium-salinity underground brackish water (500-2000ppm): LF-BW RO + LF-UF-6060W PVDF UF
3.High COD printing & dyeing wastewater: LF-BW-FR anti-fouling RO + large-area LF-UF-8060W PVDF UF
4.Seawater raw water (TDS>32000ppm): LF-SW series seawater RO + multi-stage PVDF UF
5.Food factory low-pollution raw water: LF-ULP commercial RO + LF-UF-4040 PAN UF
6.Power plant high-turbidity river water: LF-BW industrial RO + LF-UF-2880W large-flux PVDF UF
All full-series RO membrane and UF membrane selection reference data are displayed in our complete water filter element series.

Classified Industrial Application Scenarios For Dual-Membrane System
1. Semiconductor wafer high-purity water dual-membrane workshop
2. Food factory edible pure water full automatic production line
3. Large thermal power station boiler make-up water station
4. Printing & dyeing wastewater zero discharge desalination equipment
5. Pharmaceutical sterile purified water integrated system
6. Island marine seawater desalination water supply unit
Comprehensive Advantages Of Standard UF + RO Dual Membrane Process
1. Two-stage graded filtration completely block particulate and biological pollution sources of RO membrane 2. Extend RO chemical cleaning cycle from 1-2 months to over half a year, cut chemical expenditure 3. Reduce frequent shutdown production loss caused by membrane blockage 4. Steady outlet turbidity and conductivity guarantee consistent product quality 5. Compact integrated layout save factory workshop occupied area 6. One-stop supply of all UF & RO full models without multi-supplier procurement
