Long-life sanitary NF with standard 32mil runner for non-stop 24h production, anti-aging modified membrane layer with slow flux attenuation, reduce element replacement frequency & downtime cost.
Long-lasting anti-aging polyamide membrane layer ensures flux decay below 10% after 6 months of continuous operation.
Wear-resistant sanitary mesh prevents damage and fuzzing under long-term fluid scouring.
The 32 mil parallel flow channel delivers uniform flushing, lowering local contaminant accumulation that causes membrane surface aging. Wide-range pH tolerance enables frequent cyclic chemical cleaning.
