Product Introduction

Frequently Asked Questions

What is a Hollow Fiber UF Membrane Crossflow Filter?

A Hollow Fiber UF Membrane Crossflow Filter is an advanced ultrafiltration solution designed for the efficient separation of suspended solids, bacteria, and macromolecules in water and wastewater treatment.

What are the main materials used for UF membranes?

The main materials used for UF membranes include PES (Polyethersulfone), PAN (Polyacrylonitrile), and PVDF (Polyvinylidene Fluoride), each offering different properties suitable for various applications.

What is the pore size range of the UF membranes?

The pore size range of the UF membranes varies by material: PES membranes have a pore size of 0.002 - 0.01µm, PAN membranes have a pore size of 0.02µm, and PVDF membranes range from 0.03 - 0.08µm.

What industries can benefit from using UF membranes?

Industries such as drinking water treatment, industrial process water reuse, pharmaceuticals, biotechnology, food and beverage, municipal wastewater treatment, desalination pretreatment, and electronics manufacturing can benefit from UF membranes.

Can UF membranes handle high turbidity levels?

Yes, the maximum feed turbidity for different membrane types varies: PES can handle <50 NTU, PAN <80 NTU, and PVDF <100 NTU.

What is the maximum chlorine resistance for these membranes?

The maximum chlorine resistance is 2000 ppm for PES and PVDF membranes (momentarily), and 500 ppm for PAN membranes (momentarily).

What is the operating temperature range for the UF membranes?

The operating temperature range for all types of UF membranes is between 5°C and 45°C.

What are the cleaning agents compatible with UF membranes?

Compatible cleaning agents for UF membranes include NaClO (sodium hypochlorite), H₂O₂ (hydrogen peroxide), NaOH (sodium hydroxide), and HCl (hydrochloric acid).

What is the design flux for PES membrane modules?

The design flux for PES membrane modules ranges from 0.225 to 6.4 m³/0.1MPa·25°C.

How does crossflow filtration differ from dead-end filtration?

Crossflow filtration allows the feed water to flow parallel to the membrane surface, reducing fouling, while dead-end filtration forces water perpendicular to the membrane, which can lead to faster clogging.

What is the purpose of the backwash cycle in UF membranes?

The backwash cycle is optimized to improve membrane longevity and efficiency by reversing the flow to dislodge and remove accumulated particles.

What is the maximum permeate flow rate for these membranes?

The maximum permeate flow rate for all types of UF membranes is between 120 to 150 L/m²·h.

Is the UF membrane suitable for high-purity applications?

Yes, PES membranes are particularly suitable for high-purity applications due to their excellent chemical resistance and thermal stability.

What does MWCO stand for and what are the ranges for different membranes?

MWCO stands for Molecular Weight Cut-off, which indicates the range of molecular sizes that can be effectively separated by the membrane. PES membranes have an MWCO of 50k - 67k Dalton, PAN membranes 80k - 100k Dalton, and PVDF membranes 100k - 150k Dalton.

Can the UF membrane be used in harsh chemical environments?

Yes, PVDF membranes are preferred for harsh environments due to their high chlorine tolerance and chemical durability.
