Shocking! Backwashing Revives Clogged Chengrong Ultrafiltration Membranes - A Miraculous Recovery
(Serial No. 005)
Here's something you need to know: Ultrafiltration (UF) membranes are reusable powerhouses! When your water purifier's flow rate drops to a trickle, don't panic – backwashing can breathe new life into clogged membranes. The real kicker? A membrane's ability to regain its original water production efficiency after flushing is the ultimate performance test.
At the request of Beijing client Mr. Li, we conducted head-to-head testing between Chengrong's PVC Alloy UF Membranes and a competing domestic brand. The results? Mind-blowing! After backwashing, Chengrong's membranes fully restored their initial flux (100% recovery), while the competitor maxed out at 61.3%. The kicker? Chengrong delivers this superior performance at a lower price – truly earning its crown as "The King of Cost-Effective Filtration."
Putting Membranes Through Their Paces
After 120 hours of intense water production:
• Chengrong: 54 L/H flow at 0.15MP
• Competitor: 47 L/H flow at 0.15MP
This severe flux decline signaled critical membrane clogging – time for flush protocol.
Flushing 101: Forward vs. Reverse
• Forward flushing: Water flows normally through membrane pores (inside-out for these internal-pressure cartridges)
• Backwashing (game-changer!): Water reverses direction (outside-in), blasting contaminants off membrane surfaces for superior cleaning power.
Testing Matrix Reveals Clear Winner
Using 0.15MPa and 0.3MPa backwash pressures followed by six operating pressures (0.15-0.4MPa), data tells all:
0.15MPa Backwash Results
• Chengrong: 92.5%-100% flux recovery
• Competitor: 32.4%-37.7% flux recovery
Flux advantage: +234L/H to +536L/H for Chengrong
0.3MPa Backwash Results
• Chengrong: 97.9%-100% flux recovery
• Competitor: 57%-61.3% flux recovery
Flux advantage: +240L/H to +420L/H for Chengrong
Why This Matters
Flux recovery post-flushing = direct predictor of membrane lifespan. Chengrong's superior resilience means:
• Extended service life vs competitors
• Lower maintenance costs
• Reduced filter replacement frequency
Smart Choice Alert: Chengrong's PVC Alloy UF membranes deliver uncompromised performance and value. When every liter and dollar counts, there's only one industry leader – Chengrong Ultrafiltration, Where Water Speaks Trust, Not Doubts.
