PTFE is considered an ideal hydrophobic membrane material due to its excellent corrosion resistance, thermal stability and hydrophobicity. However, it is difficult to dissolve and has poor melt fluidity. Difficult to process. The current processing method for PTFE hollow fiber membranes is mechanical stretching, but the membranes prepared by this method have low porosity, which seriously restricts the efficiency of the separation process.
Membrane separation is becoming the main separation method for post-fermentation treatment. It is not only used for solid-liquid separation, but also for proteins of different molecular weights in solution. Separation, and even the entire separation process can be achieved with membranes of different specifications, including solid-liquid separation, screening of substances with different molecular weights, and product concentration.
PTFE hollow fiber membrane has been widely used in the fields of seawater desalination, printing and dyeing, papermaking, leather, electroplating, brackish water and other wastewater treatment fields. It is no longer just Materials used in niche high-difficulty wastewater fields.
Polytetrafluoroethylene hollow fiber membrane is frequently cleaned online, and the cleaning process is complex and requires the prepared chemicals to be passed through The dosage pump pressurizes the membrane into the interior of the membrane to complete cleaning. On the one hand, the online cleaning of flat membranes is achieved through aeration during operation, and on the other hand, it is achieved through online chemical cleaning. The flat membrane bioreactor can control the aeration volume of the aeration system at the bottom of the component to perform good hydraulic flushing of the membrane surface, preventing excessive deposition of sludge on the membrane surface during the suction process, and reducing the amount of sludge on the membrane surface during operation. Fouling on the membrane surface plays a controlling role.
