Sewage treatment has long been a shortcoming in many places. Many rivers and lakes have been invaded by sewage, turning black and smelly, seriously hampering people’s production and life. Turning sewage into clean water and turning clean water into drinking water has become the direction of efforts in various places. Sewage treatment has received unprecedented attention.
Traditional sewage treatment mostly uses flocculation, sedimentation and other methods, which cannot completely remove organic pollutants and heavy metals in the water. MBR sewage treatment technology can selectively separate sewage from material and liquid, greatly improving the treatment effect.
In the fields of sewage treatment and water reuse, MBR, also known as membrane bioreactor (Membrane Bio-Reactor), is a membrane separation unit and biological New water treatment technology combining treatment units. According to the structure of the membrane, it can be divided into flat membrane, tubular membrane and hollow fiber membrane, etc. According to the membrane pore size, it can be divided into microfiltration membrane, ultrafiltration membrane, nanofiltration membrane, reverse osmosis membrane, etc.
The currently independently developed ptfe sewage filtration membrane is the core component of the MBR membrane bioreactor. ptfe sewage filtration membraneMade using a biaxial stretching process, the porosity is as high as over 80%, and the filtration resistance is extremely low. It has many features when used in wastewater recycling.
It can efficiently perform solid-liquid separation to separate suspended substances, colloidal substances, and microbial flora lost from biological units in wastewater from purified water. The separation process is simple, the area is small, and the effluent quality is good. It can maintain the biomass in the biological treatment unit at a high concentration, greatly increasing the volume load. At the same time, the high efficiency of membrane separation greatly shortens the hydraulic retention time of the treatment unit, and the footprint of the bioreactor is correspondingly reduced. During long-term operation, the membrane as a filter medium is clogged, and the membrane’s water flow operation time gradually decreases. Effective backwashing and chemical cleaning can slow down the decrease in membrane flux and maintain the effective service life of the MBR system.
The independently developed and produced ptfe sewage filtration membrane has a pore size range of 0.1μm-1μm. The pore size is adjustable, has wide chemical applicability, is resistant to strong acids and alkali, and is widely used in fields such as strong corrosive solvent treatment, liquid bacteria treatment, and reclaimed water reuse.
