Ultrafiltration membrane materials and processes used in the film except for a few special separation industry ceramic or other inorganic materials, water treatment membranes are basically organic polymer materials. MBR can be used to make the film have a lot of organic polymer materials, comprising: a polyvinylidene fluoride (PVDF), polysulfone (PS), polyethersulfone (PES), polyethylene (PE), polypropylene (PP), poly tetrafluoroethylene (PTFE), polyvinylchloride (PVC), etc., while PVDF is recognized as the most outstanding properties of the membrane material of ownership, but also the most successful one. PVDF is a form of organic fluorine materials, which have a common characteristic of fluorine materials: strong chemical stability. Chemical stability means strong corrosion resistance and long service life Ningbo flat membrane device, therefore, made of PVDF membrane can be applied in a wide range of water quality flat membrane manufacturers in Ningbo, Zhejiang Province, Which professional, and has a long life. However, the same is PVDF materials, different techniques have made it out of the membrane performance is also very different, mainly in terms of the mechanical strength of the membrane, the membrane surface pollution performance, membrane porosity and pore size distribution. Conventional PVDF membrane process is called NIPS (wet-phase method), although the same excellent chemical stability NIPS membrane into the legal system, and higher filtration accuracy (typically 0.03μm), but lower mechanical strength, more suitable for the application a more stable environment in the field of water purification, sewage aeration continued application easily broken wires, affecting life. Latest PVDF membrane technology for TIPS (thermally induced phase method), TIPS membrane filtration accuracy is slightly lower (typically 0.1μm), but the high mechanical strength, suitable for continuous aeration of wastewater treatment, namely MBR applications. Times to MBR membrane using the latest technology TIPS PVDF membrane microfiltration membrane, particularly suitable for applications in continuous aeration and high levels of suspended solids in wastewater, compared with other similar products flat membrane, with high strength, high toughness, good stain resistance, high porosity, pore size distribution and narrow features. At very high filtration precision, still able to maintain a high water flux. Chemical cleaning off-line chemical cleaning agent at room temperature with a single washing, filtration performance may not fully recover the membrane, and the membrane module was immersed in an activated sludge mixture for a long time, some highly resistant bacteria and microorganisms in the membrane may Some of the weaker parts of the cumulative disturbance, easy to peel. Therefore, it is necessary to periodically clean the membrane module offline reinforced, in order to maximize recovery of the filtration performance of the membrane. Offline chemical cleaning, also known as immersion cleaning or chemically enhanced cleaning. And online chemical cleaning different chemical cleaning membrane system offline to run longer need to exit the high-pressure flat membrane Ningbo Which is good, and usually use a variety of agents, an appropriate increase in the cleaning solution temperature (about 35 ℃), higher drug concentration .
