Externally pressured PVDF ultrafiltration membrane

External Pressure Hollow Fiber Ultrafiltration Membrane

Products Introduction

• The external pressure ultrafiltration membrane module is currently dominated by hollow fiber membrane. This product adopts the external pressure structure with higher pollutant-holding capacity, unique ring gap water collection-drainage structure, and at the same time combines the air-water scrubbing mode to greatly enhance the cleaning and drainage effect of the module.

• PSD-OPUF is made of high-performance PVDF membrane material, with an average pore size of 30nm, capable of removing almost all particles, bacteria, most germs and colloids, with good chemical stability, and long term resistance to chemical cleaning with high concentration of oxidizing biocides.

Product features

• Small separation pore size, excellent water quality:

  Nominal averagepore size is 30nm, high filtration precision, can effectively filter out bacteria, viruses and colloids and other particles.

• High mechanical strength and excellent chemical resistance:

  With good mechanical properties, it can withstand repeated air scrubbing, and at the same time has excellent chemical resistance.

• High hydrophilicity and excellent wash recovery performance:

  Hydrophilic modified PVD hollow fiber membrane with good hydrophilic and excellent pollution resistance helps to maintain long-term stability of performance.

• External pressure structure with low pretreat requirements:

  The external pressure design allows larger particle size pollutants to enter, which can reduce the pretreatment process.

Product Advantages

• Low maintenance cost：

  The external pressure module structure with higher dirt-carrying capacity makes the module's ability to contain pollution significantly better than other structures, and with the external pressure water inlet, there is a large free space between the hollow fiber membranes, which allows the use of highly efficient air-water mixing scrubbing to reduce pollution.

• High rejection of pollutants and easy cleaning:

  The unique ring gap water collection-drainage design maximizes the membrane module's drainage capacity

  and effectively improves the cleaning and drainage effect of membrane module.

• Chemically stable: permanently hydrophilic polyvinylidene fluoride (PVDF) has excellent resistance to oxidation, pollution and long service life.
