The Baileke process was produced in Germany. Currently, there are 500 sets of treatment processes. It is transformed from the oxidation ditch process and covers a large area. The aeration device is a patented product and has a high degree of automation. Civil construction costs are low.
The process has no advantages other than saving civil construction investment. The water conservancy conditions are very poor and short flow is easy between pools. The process is delayed aeration, which is simply an A/O process. It is nothing more than the pool body. Earth dams are used, separated by retaining walls.
