Toray HFUG-2020AN Ultrafiltration Membrane

1. What is the Toray HFUG-2020AN membrane used for?
It's a hollow-fiber ultrafiltration membrane used for drinking water treatment, industrial process water, pretreatment ahead of seawater RO desalination, and secondary/tertiary wastewater treatment.

2. How is this different from the standard Toray HFU-2020AN?
The HFUG uses thinner membrane fibers with higher packing density, giving it a 30% smaller footprint, roughly 10% lower initial installation cost (fewer pipes and valves needed), and increased flow capacity — while maintaining the same durable membrane characteristics as the standard HFU line.

3. What is the maximum flow rate of this membrane?
15 m³/h (66 GPM) maximum feed water flow — higher than the standard HFU-2020AN's 12 m³/h rating.

4. What is the membrane's surface area?
90 m² (969 ft²) of outer membrane surface area.

5. What size is this membrane?
8.5 inch (216 mm) diameter, 2,160 mm (7.087 ft) length — the same physical footprint as the HFU-2020AN despite the higher flow capacity.

6. What is the maximum inlet pressure?
300 kPa (44 psi).

7. What is the membrane's weight?
92 kg full of water, 49 kg after draining.

8. What materials make up the housing and seals?
UPVC casing and cap, epoxy resin potting, and EPDM O-rings.

9. Is this membrane certified for drinking water?
Yes — along with drinking water, it's suited for industrial process water, RO pretreatment, and wastewater treatment applications.

10. Why choose the HFUG over the standard HFU if they're similarly priced?
The HFUG's smaller footprint and higher flow per module mean fewer units are needed for the same treatment capacity — for space-constrained installations or projects where higher throughput per module reduces overall system cost, the HFUG is the stronger choice despite the marginally higher unit price.
