Ultrafiltration Membrane & Reverse Osmosis Membrane Complete Selection Guide Avoid Wrong Procurement Loss

Countless engineering purchasers blindly purchase single Reverse Osmosis membrane without supporting matched Ultrafiltration membrane module according to actual raw water test reports, resulting in frequent blockage of each Reverse Osmosis membrane element and unstable outlet conductivity of RO membrane filter. Correct dual membrane system collocation must be judged by three core indicators: raw water TDS salinity, COD organic content and raw water turbidity. This professional classified selection guide sorts targeted matching schemes based on full catalog product parameters, helping global water treatment buyers avoid wrong model procurement loss and cut annual system operation cost. Every matched combination of Ultrafiltration membrane module and Reverse Osmosis membrane element can be fully browsed in our water filter element.

Classified Raw Water Matching Rules & Corresponding Industrial Fields

1. Low TDS Tap Water (TDS＜500ppm): LF-XULP Reverse Osmosis membrane + PAN Ultrafiltration membrane module — Food & Office Central Pure Water

2. Medium Brackish Water (500–2000ppm): LF-BW RO membrane element + LF-UF-6060W UF membrane — Power Plant Boiler Feed Water

3. High COD Industrial Sewage: LF-BW-FR RO membrane filter + LF-UF-8060W Large-Flux Ultrafiltration membrane — Printing & Dyeing Zero Discharge

4. Seawater Raw Water (TDS＞32000ppm): LF-SW Reverse Osmosis membrane + Multi-Stage PVDF Ultrafiltration membrane module — Island Desalination Station

5. Food Factory Low Pollution Raw Water: LF-ULP RO membrane + Small PAN UF membrane — Bottled Beverage Production Line

6. High-Turbidity River Cooling Water: LF-BW Reverse Osmosis membrane filter + LF-UF-2880W Large-Area Ultrafiltration membrane — Thermal Power Station

Long-Term Cost-Saving Advantages Of Standard UF+RO Dual Membrane System

1. Two-stage graded filtration completely eliminate all particulate and biological pollution sources that damage Reverse Osmosis membrane

2. Extend chemical cleaning cycle of each Reverse Osmosis membrane element from 1–2 months to over half a year

3. Reduce chemical reagent consumption and production shutdown loss caused by maintaining RO membrane filter

4. Stabilize outlet turbidity and conductivity to guarantee consistent production quality with matched UF membrane

5. Compact integrated layout saves factory workshop occupied area for the whole Ultrafiltration membrane module + RO membrane set

6. One-stop full supply of all Reverse Osmosis membrane element and Ultrafiltration membrane without multi-supplier separate procurement
