Engelbart SST biological technology is a highly efficient activated sludge treatment technology. Its predecessor is BioDopp process, which is invented by Dr. Wilke Engelbart and his uncle Fritz engelbart in the 1970s in Germany. The BioDopp process was first introduced to China in 2003, where Dr. Engelbart provided basic design and core equipment. Later, it was promoted via process package mode, and now has demonstration projects in many different fields, such as municipal sewage, chemical wastewater, pharmaceutical wastewater, livestock wastewater and other industries. Under the leadership of Dr. Wilke Engelbart, scientific researchers and engineers in Germany and China have been working together to continuously improve the process. After more than 40 years of research and practice, and learned from extensive experiments and lessons of wastewater treatment in different industries, we have developed engelbart SST biological technology. Compared with the original BioDopp technology, the defects of its process and equipment are eliminated one by one, and its advantages are further reinforced.

The process follows the laws of nature and maximizes the biological efficiency. Its main advantages are: short process, compact layout, high processing efficiency, low energy consumption, and convenient management and maintenance.
