Flat membrane element adopts PTFE membrane material, which has strong anti-pollution ability, low filtration resistance, and can realize gravity filtration. Canpure CPFC series cassette flat membrane module adopts a unique combination of box body, high filling density and large filtration area. Membrane modules can be arranged in a stack, with a small footprint, simple system integration, and low operating costs.
Polytetrafluoroethylene (PTFE) membrane material
Polytetrafluoroethylene (PTFE) has very strong chemical stability and does not adhere to any surface properties. Canpure PTFE flat membrane can withstand strong acids, strong alkalis and strong oxidants for cleaning.
Flat membrane elements use proprietary technology to make PTFE membranes permanently hydrophilic. Pure water flux is greater than 1000L / m2 · hr at 1 mH2O.
Gravity filtration membrane
PTFE membrane is manufactured by biaxial stretching process, with a porosity of more than 80% and extremely low filtration resistance. Generally, the transmembrane pressure difference under the flux is less than 0.5mH2O, which makes gravity filtration (no pump filtration) possible.
Open box structure / patented technology /
Cassette flat membrane module adopts the structure with upper and lower ends open, which can effectively avoid the entanglement and clogging of hair and paper dust and sewage sludge in sewage.
High packing density
Cassette flat membrane module adopts a unique combination of multiple layers of cabinets, which significantly increases the packing density of the membrane module.
The cassette flat membrane module is stacked in multiple layers, which greatly reduces the projection area of the MBR membrane system, thereby greatly reducing the amount of operating aeration and making the membrane system operating cost lower.
