Most project engineers ignore complete front-end pre-filtration design, which directly leads to irreversible scratch and severe biological fouling on expensive Reverse Osmosis membrane. Ordinary multi-media filter and security cartridge can only trap large sand grains, failing to intercept nano-scale colloids, algae and microorganisms that quickly contaminate every Reverse Osmosis membrane element. Our PVDF external pressure Ultrafiltration membrane (also named Ultrafiltration membrane module) adopts modified hydrophilic hollow fiber material with 0.01μm filtration precision, intercepting over 99% suspended micro-particles and microbes, stably controlling inlet SDI value below 3 for all types of RO membrane, RO membrane element and RO membrane filter. This high oxidation resistant UF membrane can withstand high-concentration sodium hypochlorite backwashing without fiber fracture, serving as the first-line protective barrier for the full series of Reverse Osmosis membrane filter. All PVDF Ultrafiltration membrane module and matched full-series Reverse Osmosis membrane element are listed in our water filter element.
Full Range Pretreatment Application Scenarios
1. All LF series Reverse Osmosis membrane system front-end protective pretreatment
2. Oilfield oily produced water solid-liquid separation treatment equipment
3. Municipal sewage reuse pre-filtration process section
4. Power plant circulating cooling water turbidity reduction unit
5. Printing and dyeing high organic wastewater primary filtration line
6. Seawater desalination multi-stage pretreatment matching for RO membrane filter
PVDF UF Membrane Protective Performance Advantages
1. Super hydrophilic fiber material resists oil and organic pollutant adhesion for this Ultrafiltration membrane module
2. Ultra-high tensile strength avoids fiber breakage during high-flow backwashing of each UF membrane
3. Excellent chlorine oxidation resistance fits long-term cyclic cleaning before Reverse Osmosis membrane element
4. Automatic online backwashing function drastically cuts manual maintenance labor cost of the full Reverse Osmosis membrane system
5. Customizable membrane area specifications match all tonnage RO membrane and RO membrane element
6. Compatible with all mainstream high-flow security filters to form double-layer protection for RO membrane filter
