2. Mitsubishi Chemical MBR film 60E0025SA cleaning method:

★Mitsubishi Chemical MBR membrane module self-cleaning

Mitsubishi Chemical's MBR membrane module needs to be stopped for at least 1 minute for self-cleaning after 7 minutes of suction. It is recommended not to backwash

★Mitsubishi Chemical MBR membrane maintenance and cleaning

Perform recovery cleaning once a week. Use Naocl with a concentration of 300ppm-500ppm to pass the liquid quantitatively from the secondary side for 15-30 minutes. The amount of the chemical solution is 2L/m2 per unit membrane area + the capacity of the introduction pipe. During implementation, stop aeration. This operation basically runs automatically.

★Mitsubishi Chemical MBR membrane recovery cleaning

The recovery cleaning is carried out every 3 months or when the suction pressure exceeds 30KPa. The purpose is to remove the blockage of the membrane and restore the pressure difference between the membranes to the initial value.

The aeration was stopped, and Naocl with a concentration of 3000 ppm was used to quantitatively pass the liquid from the secondary side for 30 minutes. The amount of the chemical liquid was 2L/m2 per unit membrane area + the capacity of the introduction pipe. After the liquid is passed, keep it in this state for 30-90 minutes. Aeration for 5 minutes before suction during operation

★Mitsubishi Chemical MBR membrane immersion cleaning

When the pressure difference between the membranes cannot be restored by the recovery cleaning, immerse the entire membrane module in a solution of Naocl or acid (1-2% citric acid, 0.1-0.5N hydrochloric acid or sulfuric acid) with a concentration of 3000 ppm for cleaning, and the immersion time Naocl is 6-24 hours, acid is about 2 hours.

3. Product advantages of Mitsubishi Chemical's MBR film 60E0025SA: 

　　◆Excellent volume power, energy saving, easy maintenance 

　　◆Use PVDF hollow fiber membrane (SADF membrane)

　　◆Suitable for domestic sewage and industrial wastewater

　　◆High water permeability, excellent chemical resistance, high strength

4. Features of Mitsubishi Chemical's MBR film 60E0025SA:

◆Mitsubishi Chemical's MBR membrane has a large flux

　　The flux of clean water is about 3 times larger than the flux of the original PE membrane, which enhances the processing capacity of a single membrane and has the advantage of a small footprint.

◆Mitsubishi Chemical MBR membrane energy saving

　　(1) The membrane flux is significantly improved, and the amount of purge air in the MBR membrane zone is reduced to 2/3 of the original membrane;

　　(2) The processing capacity of a single diaphragm is increased, and the number of necessary diaphragms is reduced. At the same time, the auxiliary equipment is simple, and the installation space of the membrane element is reduced.

◆Mitsubishi Chemical MBR membrane is easy to maintain 

　　(1) The cleaning efficiency of the membrane surface is improved, and long-term, stable, high-throughput operation is realized;

　　(2) The membrane material is made of fluororesin (polyvinylidene fluoride), which has high chemical stability and strong oxygen resistance. Basically, it can be cleaned online.
