What is the difference between ultrafiltration thermal membrane production and wet membrane production?

Wet uf membrane forming characteristics:

• Uf membrane formation driving force is mass transfer

• High filtering precision 

• Good hydrophilicity 

• Lower mechanical strength

Thermal uf membrane forming characteristics: 

• The driving force for membrane formation is the high crystallinity of the heat transfer membrane

• High mechanical strength 

• Good chemical resistance 

• Belongs to Ultra Micro Filtration

Wet process uf membrane characteristics:  

•  Filtration pore size: 0.04μm (SDI<2 turbidity<0.1 NTU); 

• Asymmetric cavernous membrane, single cortex, low water permeability resistance, good retention; 

• Permanent hydrophilic modification, good pollution resistance and stable flux; 

• Pure water flux: 500L/m2 h bar, at 25℃;

   

Thermal uf membrane forming characteristics:  

• Continuously challenge the strength of the membrane filament to overcome 10 Newtons;

•  Filament strength is nearly 4 times that of "Non-solvent Induced Phase Separation (NIPS)" and nearly 2 times that of "Composite-Thermal Induced Phase Separation (C-TIPS)";

• Filtration pore size: 0.1μm (SDI<2 turbidity<0.1 NTU);

•  Bi-continuous 3D network structure is evenly distributed;

• Pure water flux: 1000L/m2 h bar, at 25℃;
