Description
AQU‑250A UF Membrane – Ultrafiltration Hollow Fiber Element
The AQU‑250A UF Membrane is a high-performance hollow fiber filter designed for both domestic and commercial water systems. It removes suspended solids, bacteria, and other impurities efficiently, ensuring clear, safe water.
With robust construction, this ultrafiltration element performs reliably under continuous operation, making it suitable for homes, offices, and small-scale commercial setups.
How Ultrafiltration Works
Water enters the UF membrane under low pressure and passes through microscopic hollow fibers. These fibers trap particles, bacteria, and turbidity, while allowing clean water to flow out.
Regular monitoring of flow and system performance ensures the membrane continues to deliver high-quality water consistently.
Key Benefits
- Efficient removal of bacteria, turbidity, and suspended solids
- Hollow fiber design maximizes surface area for filtration
- Durable construction for long-lasting performance
- Easy installation in domestic and commercial UF systems
- Consistent water quality with low maintenance
