Characteristics of Mitsubishi MBR Membrane Bioreactor in Japan
Mitsubishi MBR Membrane in Japan introduced advanced floating algae technology concept to solve the technical problems of broken wires, small processing ability and difficult cleaning of MBR membrane bioreactor in wastewater reuse in many sewage treatment plants. This technology changed the traditional one-sided production of water from both sides, so it is also convenient to add the same standard inner membrane filament. Length, then added unit membrane area. The unilateral water production of the membrane module is unequal, so the membrane module can float in the reactor like algae when it is running. Instead, we try to add a fixed bracket to the floating part so that it can not knot when it is floating, thus improving the processing power.
The breakage of membrane module is caused by its fixed viscose skills. It is an ideal way to control the breakage by choosing multi-level and flexible viscose skills. The cleaning problem of membrane module is also the technical guarantee for MBR to operate safely for a long time. The planning method of choosing one-side effluent and one-side air-flushing mixing is more helpful to reduce the cleaning frequency of membrane module in vitro. In order to improve the anti-fouling ability of the membrane, Mitsubishi MBR membrane uses PVDF raw material treated by hydrophilic modification as membrane material.
Using the above new skills and materials, the Mitsubishi MBR membrane module has the following advantages in operation:
1. High efficiency and energy saving
Because of the addition of unit membrane area, a small number of membrane components can be used for large water treatment, high power. Membrane modules can maintain high throughput at low pressure of 0.05 MPa, so the energy consumption per unit volume of filtration is very low.
2. High Strength, Continuous Wire
Membrane filament adopts advanced viscose technology, which effectively controls the problem of broken filament caused by fixed viscose technology.
3. Anti-pollution and long service life
Because PVDF material treated by hydrophilic modification is chosen as membrane material, the flux and anti-pollution ability of MBR membrane module are obviously improved, and the service life is long.
4. Easy to clean
Choose the planning method of mixing water and air at the same time. This method helps to reduce the cleaning frequency of membrane components.
5. Low operating cost and quick recovery of investment
Selection of high-performance membrane components, low energy consumption, low operating costs, stable water quality, recyclable, saving water and sewage charges, investment recovery period is short.
6. Modular planning with high degree of automation
The common patented appearance and highly integrated modular planning are selected to facilitate capacity expansion, automatic control and high degree of automation.
