Toray HFU-2020AN Ultrafiltration Membrane

Toray's membrane construction is highly resistant to chlorine and strong acids, which allows for better cleaning and optimization of filtration flux rates after cleaning. The hollow fiber modules effectively remove suspended solids, viruses, and bacteria and are certified for drinking water applications.

The Toray HFU-2020AN Ultrafiltration Membrane is built for applications where consistent water quality matters more than upfront cost — here's what actually sets it apart:

• Certified for drinking water applications — the hollow fiber modules remove suspended solids, viruses, and bacteria to a standard suitable for potable water, not just industrial process water.

• High chemical resistance — the membrane construction tolerates chlorine and strong acids well, which means more aggressive cleaning cycles are possible without degrading performance, keeping flux rates high even after repeated cleaning.

• Genuinely fine filtration — a 0.01µm nominal pore size sits well below sediment or standard carbon filtration, removing pathogens that coarser pre-filters simply pass through.

• Versatile across four real use cases — drinking water, industrial process water, RO pretreatment for desalination, and secondary/tertiary wastewater treatment, meaning one membrane spec can serve multiple stages of a treatment plant.

• Low energy, simple control — designed for straightforward operation without complex automation requirements, keeping running costs down.

• Backed by industry certification — associated with the Association of Membrane Separation Technology of Japan, a recognized technical body in this field.

1. What is the Toray HFU-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. What is the membrane made of, and what's the pore size?
PVDF (Polyvinylidene Fluoride), with a nominal pore size of 0.01µm — fine enough to remove suspended solids, bacteria, and viruses.

3. Is this membrane certified for drinking water?
Yes — it's certified for drinking water applications, in addition to industrial and wastewater use.

4. What is the membrane's surface area and flow capacity?
72 m² (775 ft²) of outer membrane surface area, with a feedwater/filtrate flow rate of 12 m³/h (53 GPM).

5. What are the operating pressure and temperature limits?
Maximum inlet and backwash pressure of 300 kPa (43.5 psi), with an operating temperature range of 0–40°C (32–104°F).

6. What pH range can this membrane tolerate?
pH 1–10 during normal filtration, extending to pH 0–12 during chemical cleaning.

7. What is the membrane's size and weight?
216 mm (8.5 in) diameter, 2,160 mm (7.087 ft) length. Weighs 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 — chosen for chemical compatibility with the membrane's operating conditions.

9. Why is chemical resistance important for this membrane?
Its tolerance to chlorine and strong acids allows for more effective and frequent cleaning cycles, which helps maintain filtration flux (flow performance) over the membrane's service life rather than degrading it.
