Printing & dyeing wastewater, steel plant circulating cooling water and municipal reclaimed water carry massive organic sludge, algae and biological mucus. Ordinary common Reverse Osmosis membrane will be covered by dense biofilm within 1–2 months of continuous operation, causing sharp differential pressure surge, reduced daily water yield and mandatory monthly chemical cleaning shutdown, which brings huge production pause loss and extra chemical reagent procurement cost. Our LF-BW-FR anti-fouling Reverse Osmosis membrane element adopts upgraded super hydrophilic modified TFC coating and exclusive 34mil widened internal flow channel, which greatly slows organic and microbial adhesion on the membrane surface. This industrial heavy-duty Reverse Osmosis membrane filter can maintain a stable salt rejection rate above 99.6 under long-term high-COD raw water inlet, and must be matched with large-flux PVDF Ultrafiltration membrane module to cut the front pollution load before water flows into each RO membrane. All LF-BW-FR series industrial RO membrane element and matched large-area UF membrane can be fully viewed and compared inside our water filter element.
Main Industrial Wastewater Application Scenarios
1. Printing and dyeing factory wastewater zero discharge desalination equipment
2. Steel mill circulating cooling water advanced recycling station
3. Municipal secondary sewage landscape water recovery project
4. Landfill leachate secondary deep reverse osmosis treatment line
5. Petrochemical high organic waste water recovery unit
6. Electroplating factory heavy metal wastewater pretreatment system
Core Anti-Pollution Performance Highlights Of LF-BW-FR RO Membrane Filter
1. Special hydrophilic coating inhibits organic and microbial adhesion on Reverse Osmosis membrane surface permanently
2. Wider 34mil feed channel reduces dirt stacking inside each independent Reverse Osmosis membrane element
3. Outstanding flux full recovery after cyclic acid and alkali cleaning for this industrial RO membrane filter
4. Wide chemical cleaning pH tolerance range 1–13, compatible with high-concentration industrial detergents
5. Standard 4-inch & 8-inch universal overall size, fit all mainstream FRP pressure vessels for RO membrane
6. Large-flux PVDF Ultrafiltration membrane module matching extends the chemical cleaning cycle of Reverse Osmosis membrane filter to over 6 months
