The customer from Panama , we have cooperated for 5 years .  every year they purchased sewage treatment plant , wastewater treatment plant , and wastewater treatment accessories from our factory .   we always supply the design for the customer , do OEM service , they can use their own brand and loag on the plant . 

The mbbr sewage treatment plant we supplied get the good results outlet standard ,so the client trust our factory very much . 

MBBR wastewater treatment plant   is very good  for the domestic wastewater treatment , and it is more and more popular in the wast water treatment .

The invention discloses an pretreatment method based on MBBR for removing ammonia nitrogen from slightly polluted water, and belongs to the field of drinking water purification. The method adopts a MBBR technology to process the slightly polluted water, and aims to solve the problems of slow start of biochemical technology, unstable processing effect, and bad low-temperature processing effect. The method comprises the following steps: inoculation start and continuous flow operation; finally the ammonia nitrogen membrane surface load is 0.45 to 2.25 gN/m<2>/d, the ammonia nitrogen concentration is less than or equal to 0.5 mg/L, and the drinking water standard on ammonia nitrogen is met. The MBBR technology has the advantages of small area occupation, simple operation, and reliable operation; does not contain a fixed bed process, so blood worms are not easy to generate; avoids the dead area phenomenon caused by uneven water distribution; and has a higher oxygen utilization rate and lower energy consumption of aeration and fluidization, compared to those of the biological fluidized bed technology.
