wastewater and recycled activated sludge are introduced typically at several points in the aeration tank. The organic load on the aeration tank, MLSS concentration, and oxygen demand are uniform throughout the tank. An advantage of the CMAS process is the dilution of shock loads that occur in the treatment of industrial wastewaters. The CMAS process is relatively simple to operate but tends to ha
2. Value Enhancement
For value enhancement, in the view point of regional development, the result was not that successful. To enhance the created value, the knowledge and technology should be transferred to the region consistently, but most of transnational pharmaceutical companies in Korea including Pfizer have a defensive stand for that.
All pharmaceutical corporations in Korea are the m

-Interrupt emission of rainwater in retaining facility, as flow rate is enough by precipitation
2.Sedimentation of retaining facility
-The longer operating time is, the more sediment is piled up. So function is declined.
3.Non-point source
-Because rainwater isn’t pass the retaining facility and is inpoured, pollutions are expect.
