MBR process sewage treatment plant in the world is becoming large-scale

At present, the current situation of large-scale MBR sewage treatment plant, a set of existing data (from www.theMBRsite.com) is worth attention.

The table above lists the MBR sewage treatment plants larger than 150,000 tons, and those less than 150,000 tons are not listed. It can be seen that the MBR scale today is not the same as it was 10 years ago. Back then, the 45,000 cubic metres per day North Canal Sewage Treatment Plant in Germany was the world's largest MBR sewage treatment plant in 2005, and it is no longer on the list of large MBR sewage treatment plants. Other MBR plants, such as the Brescia MBR plant in Italy, were widely praised at the time and are now rarely mentioned.

The European giant Seine Ava sewage treatment plant in Paris, France, also introduced the MBR process. Seine Ava is the largest sewage treatment plant in Europe. It treats 75% of Paris's sewage with an inflow of 1.21 million tons per day. The treatment process is divided into two lines: 1.1 million tons per day for traditional processes, and 2.0 million tons per day for MBR processes with an average scale of 200,000 tons and a peak flow of 360,000 tons for Wastewater Treatment (CRC P). RESS).

This scenario reminds us of the MBR of 10 years ago. Ten years ago, many people thought that MBR scale was suitable for the scale of less than 100,000 tons. The average daily MBR of the highest Swedish Henriksdal sewage treatment plant reached 530 thousand tons. The 500,000-ton MBR may be the pinnacle of MBR development. On the one hand, this scale of sewage treatment plant is rarely built, on the other hand, investment, risk and other costs are rising.

That is, about six to seven years ago, the Brightwater Sewage Treatment Plant in Seattle became the largest MBR treatment plant in the United States. At that time, there were more reports on MBR research. Now the size of MBR monomer is increasing, but it is no longer a hot topic of technical discussion.
