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.
The main materials used for UF membranes include PES (Polyethersulfone), PAN (Polyacrylonitrile), and PVDF (Polyvinylidene Fluoride), each offering different properties suitable for various applications.
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.
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.
Yes, the maximum feed turbidity for different membrane types varies: PES can handle <50 NTU, PAN <80 NTU, and PVDF <100 NTU.
The maximum chlorine resistance is 2000 ppm for PES and PVDF membranes (momentarily), and 500 ppm for PAN membranes (momentarily).
The operating temperature range for all types of UF membranes is between 5°C and 45°C.
Compatible cleaning agents for UF membranes include NaClO (sodium hypochlorite), H₂O₂ (hydrogen peroxide), NaOH (sodium hydroxide), and HCl (hydrochloric acid).
The design flux for PES membrane modules ranges from 0.225 to 6.4 m³/0.1MPa·25°C.
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.
The backwash cycle is optimized to improve membrane longevity and efficiency by reversing the flow to dislodge and remove accumulated particles.
The maximum permeate flow rate for all types of UF membranes is between 120 to 150 L/m²·h.
Yes, PES membranes are particularly suitable for high-purity applications due to their excellent chemical resistance and thermal stability.
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.
Yes, PVDF membranes are preferred for harsh environments due to their high chlorine tolerance and chemical durability.
