MBR membrane waste water treatment system introduction
MBR membrane waste water treatment system is an advanced sewage treatment technology integrating film separation technology with biological treatment technology.
MBR membrane waste water treatment system, full name is bio retator, represents the effective integration of membrane technology and biological technology. It alternative the binary storage tanks in common waste water treatment with special film components to achieve the active mud trap effect and large molecular organic substances in the sewage treatment water. Water retention time (HRT) and mud retention time (SLT) of this system can be controlled separately, thus optimization of processing efficiency and improve system performance stability.

MBR film sewage treatment system component
The content of the MBR film sewage treatment system is mainly composed of membrane separator, biological reactor as well as auxiliary tank body, blowing aeration system, rotz fan, slurry return pump, cleaning system, Self-control system for tools and pipe valves and so on. Of them, aeration, extraction film and solid liquid separation membrane are common Film Classification, series and forms of these films are diverse, such as flat plate type, tube type, spiral type and hollow fiber type, The suitable type can be selected according to actual needs.

MBR film sewage treatment system features
1. high efficiency solid liquid separation: due to the small hole size of the bulbA membrane, most of the suspension materials and bacteria can be stuck, water quality production is good, can be used directly as new water sources.
2. high concentration of mud: The system can maintain high biomass, which is advantageous to enhance the volume load and treatment efficiency.
3. modular and integrated design: make the system structure compact, small footprints, convenient to expand and move.
4. strong adaptation and flexibility: strong adaptation to input water quality change and flexibility.
5. lower residual mud production: reduces mud treatment and treatment cost.

MBR membrane waste water treatment system application field
1. urban sewage treatment: the MBR technology is used to solve urban treatment of domestic sewage to improve the recycling efficiency and improve living environment. Large sewage treatment factories use MBR film technology to meet the needs of efficient treatment.
2. Building water reuse: in construction areas, MBR membrane technology is applied to medium water reuse system, treatment of sewer water back to non-drinking water needs, such as toilet discharge, irrigation and so on. V. T.
3. Industrial sewage treatment: for industrial sewage, particularly the industrial sewage containing non-degradable organic substances or special discharge standards, MBR offers a high-efficient processing solution.
4. hospital sewage treatment: hospital sewage contains many germs and residue. The MBR system can effectively remove these contaminants and ensure safe water quality.
5. Small household or industrial sewage treatment: MBR is originally applied to the small household or industrial sewage treatment projects, with the evolution of technology, its application range continues to expand.
6. Urban Sewage Treatment Project: with the appearance of the submersible MBR process built in low energy consumption, the MBR works with reduced energy consumption, makes it suitable for bigger urban sewage treatment projects.

MBR membrane waste water treatment system is a new sewage treatment process that combines biological treatment with film separation technology. In this system, the first sewage caused by pre-treatment steps, such as screen filtration or chroma, to eliminate most suspended substances and large grain impurities. Pre-treatment water then goes into the biological reactor (also called biochemical tank), where the creatures are provided with a proper growth environment through blowing aeration, Adopt the metabolism action of creatures to reduce soluble organic substances, convert to biomass and water harmless.

Then it is the core component of MBR-membrane separator. Sewage after biological treatment pass through the membrane holes under pressure, due to diaphragm trap effect, most floating substances, bacteria and virus, etc. V., stuck by the film, so get high quality osmosis water. In this process, the high precision and stability of the membrane guarantees the water production quality in accordance with recycling standards. In addition, the HRT and SLT of the MBR system is controlled independent over traditional binary tanks, allowing for better treatment and less the rest of the mud.

To keep the membrane absorbed and prevent fatigue of contaminants on the film surface area, system periodical physical or chemical cleaning. Some of the advanced MBR systems are also equipped with automatic cleaning and maintenance processes which help reduce the needs of manual operation and increasing the smart level of the system.

Although the MBR system has a significant advantage of processing effects, but in some cases, it can be integrated with RO water treatment system to meet strict water treatment standards or for further treatment. RO system works as a secondary depth treatment vehicle to eliminate solvents and small ions, such as salt and some minerals, still in water even after MBR handling. At this time, the MBR system is pre-processed, first eliminate most of suspension and organic substances, then RO system continue to clean, in the end, get more purified water, Suitable for industrial ultra-pure water preparation, higher drinking water standard requirements.

In general, MBR film sewage treatment system integrating the high efficiency of biotreatment and film technology precision, its technology process is brief and efficient, and easy to achieve automatic management, Is one of the important technologies in modern sewage treatment and water resources recycling. With improved environmental requirements and hi-tech progress, the MBR system has great potential in the future and will continue to optimization of waste water treatment efficiency, essential part of the environmental protection and sustainability development.

The MBR film sewage treatment system first removes biodegraded organic contaminants in activated mud, then use the film to separate out pure water and activated mud.
Hollow fiber membrane is tube-shaped, on the wall of the pipe there are small holes, which can retain active mud water along with the majority of floating objects, producing clear water. So that the film can work continuously and stably for a long time, under the membrane must do a certain amount of aeration, so both the biological oxygen need and the film wire is constantly vibrating, to prevent the pullutation of the filter surface.
By combining organic film separation technology in separate technique with traditional sewage biotreatment technology, The MBR process not only helps to save on the construction of binary tank but also greatly improve solid liquid separation efficiency and speed of biochemical reaction Due to the increase of concentration of mud active in the aerator tank and the appearance of specific bacteria (especially the preferred plant) in the mud. In the same time, many featured problems exist in the traditional active mud method were basically resolved by reducing the F/M ratio to reduce the remaining mud production (or even not bad at all).
