Ultrafiltration Membrane Equipment

Overview of Ultrafiltration Membrane Equipment




Ultrafiltration (UF) membrane equipment uses ultrafiltration membranes as the core component to filter solutions under low pressure. Through the sieving mechanism, it retains large molecules, suspended particles, and bacteria, achieving fluid separation, concentration, and purification. With pore sizes typically between 0.01 to 0.1 microns, UF membranes are suitable for various liquid filtration and purification processes.




Key Features of Ultrafiltration Membrane Equipment





Heat and Corrosion Resistance: Polyvinylidene fluoride (PVDF) membranes offer excellent heat and corrosion resistance, making them suitable for various chemical environments.

Anti-Fouling: Modified PVDF membranes with hydrophilic and anti-fouling treatments effectively reduce contamination buildup, extending membrane lifespan.

High Strength and Flexibility: Made from durable materials such as PVDF, polypropylene (PP), and polysulfone/polyethersulfone (PS/PES), the membranes have high structural strength and toughness, tolerating intense aeration and chemical cleaning.

Wide pH Compatibility: Most membranes function effectively within a pH range of 1-14, catering to diverse industrial needs.

High Design Flux: Initial flux can reach ≥12 m³/h, and the large membrane surface area accommodates high water flow processing capacity.



Applications




Seawater Desalination Pretreatment: Removes suspended particles and large molecules during the early stages of seawater desalination.


Water Reclamation: Treats and recycles wastewater in urban and industrial settings, reducing water resource wastage.


Membrane Bioreactors (MBR): Combines biological treatment with membrane separation for effective wastewater treatment.

Drinking Water Treatment: Purifies groundwater and surface water to ensure safe and high-quality drinking water.

Food and Pharmaceutical Industry: Filters liquids in food processing and purifies biopharmaceutical formulations in the medical field.

Degassing Treatment: Removes gas components from water using the hydrophobic nature of the UF membrane.
