Product introduction

Introduction of MBR sewage treatment equipment
MBR sewage treatment equipment is a kind of high efficiency sewage treatment equipment which combines membrane separation technology and biological treatment technology.

This device, full name Membrane Bio-Reactor, effectively combines membrane technology and biotechnology. It uses efficient membrane components to replace the secondary sedimentation tank step in the traditional wastewater treatment process, thereby effectively trapping activated sludge and macromolecular organic matter. Hydraulic retention time (HRT) and sludge retention time (SRT) can be independently controlled to optimize treatment and improve system operational stability.


MBR sewage treatment equipment composition
MBR sewage treatment equipment mainly includes membrane separation unit, bioreactor and auxiliary pool body, blast aeration system, Roots fan, sludge return pump, cleaning system, automatic control system and pipeline valve. Common membrane types are aeration membrane, extraction membrane and solid-liquid separation membrane, these membranes have a variety of forms, including plate, tube, spiral and hollow fiber type, can be selected according to actual needs.


Characteristics of MBR sewage treatment equipment
1. Efficient solid-liquid separation: the membrane with a fine aperture can trap most of the suspended matter and microorganisms to ensure that the quality of the water produced meets the standard of recycled water.
2. High concentration activated sludge: maintain high biomass, improve biochemical treatment efficiency and volume load.
3. Compact modular design: small footprint, easy to expand and migrate.
4. Strong adaptability and flexibility: adapt to the change of raw water quality, easy to operate.
5. Low residual sludge production: reduce subsequent treatment costs.


MBR sewage treatment equipment application field
1. Urban sewage treatment: It is used to improve the water recycling rate, improve the living environment, and meet the efficient needs of large-scale sewage treatment.
2. Building water reuse: The treated water quality is suitable for non-drinking needs, such as flushing and irrigation.
3. Industrial wastewater treatment: Provide efficient solutions for industrial wastewater containing refractory organic matter or with special discharge standards.
4. Hospital wastewater treatment: effectively remove pathogens and drug residues to ensure safe water quality.
5. Small industrial or household sewage treatment: suitable for initial small-scale applications, and can be expanded with technological progress.
6. Large-scale municipal sewage treatment projects: The submerged MBR process reduces energy consumption and is suitable for large-scale municipal projects.

Technical principle of

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 production process of

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).
