Composite thermally induced phase separation PVDF ultrafiltration membrane / patented technology /
Canpure PVDF external pressure ultrafiltration membrane is manufactured using the original composite thermally induced phase separation (c-TIPS) technology. Its membrane filament strength is greater than that of PVDF membrane prepared by the traditional immersion precipitation method (NIPS), and the filtration accuracy is higher than that of the PVDF membrane prepared by the ordinary thermally induced phase separation method (TIPS).
Permanent hydrophilicity / proprietary technology /
Canpure's external pressure ultrafiltration membrane adds hydrophilic substances and special cross-linking technology during the preparation process, so that the hydrophilicity of the membrane is permanently retained, the water flux is more stable, and the membrane's pollution resistance and cleaning recovery properties are obvious improve.
High oxidation resistance
Canpure PVDF external pressure ultrafiltration membrane has high crystallinity and can withstand higher concentrations of oxidants, so it can obtain a more thorough cleaning effect and a longer life.
High intensity and high flux
The strength of canpure external pressure ultrafiltration membrane filament is 10MPa,
The standard product water flux is 400L/m2 · h · bar, at 25℃.
Unique aeration structure
The Canpure external pressure ultrafiltration membrane module uses a unique internal aeration device to ensure more uniform aeration and better air scrubbing effect.
Bundle integrated distribution / proprietary technology /
The canpure external pressure ultrafiltration membrane module has the most beam splitting among similar products, which effectively ensures a more uniform water flow distribution in the module.
Soft rubber root protection / proprietary technology /
The soft glue pouring technology pioneered by canpure realizes the flexible connection between the root of the membrane wire and the pouring layer, and eliminates the hidden danger of the root fracture of the membrane wire.
