Most industrial water treatment failures of RO membrane are caused by incomplete pretreatment without UF membrane. Raw industrial water contains massive clay colloids, algae and biological slime, which traditional multi-media filters and single security filters cannot fully intercept. Tiny colloids will form dense pollution layers on the surface of RO membrane, resulting in rising operating pressure, reduced water yield and frequent chemical cleaning. UF membrane forms an absolute physical interception barrier, stably controlling inlet SDI ≤3 to protect expensive RO elements.
Matched UF membrane modules and supporting high-flow filter cartridge for RO systems are available in our professional water filter element series.
Application Fields
1. Large-scale industrial ultrapure water projects with long-term continuous operation
2. Refinery produced water recycling and petrochemical wastewater treatment lines
3. Municipal wastewater reuse projects requiring long-term stable desalination
4. Pharmaceutical factory purified water production lines with strict microbial standards
5. Large power plant boiler make-up water dual-membrane treatment system
6. Electronic factory wafer cleaning water ultra-filtration pretreatment
Core Selling Points
1. Complete biological pollutant interception: Remove 99% of bacteria, viruses and organic colloids to avoid RO biofouling
2. Extend RO service life: Reduce annual RO membrane replacement cost by more than 40%
3. Reduce maintenance frequency: RO chemical cleaning cycle extended from 1–2 months to over 6 months
4. Match two-stage filtration scheme: Cooperate with high-flow filter cartridge to realize double protection
5. Automatic backwashing: Save manual cleaning labor and reduce chemical agent consumption
6. Adapt to complex raw water quality: Stable operation under high turbidity, algae-rich seasonal raw water
Our recommended standard process: Raw water → Multimedia filter → PVDF UF membrane → high-flow filter cartridge → High-pressure pump → RO membrane. This mature scheme has been applied in hundreds of global industrial water projects.
