Sentis AG Dairy Company

Sentis AG is a dairy company in Macedonia and producer of milk, yoghurts and cheeses for markets in Macedonia and the region. Sentis started to treat the wastewater some years ago. It was chosen to install a Moving Bed Biofilm Reactor (MBBR). The wastewater treatment process follows a cycle of aeration-sedimentation-discharge. The effluent standards were:

• BOD5 (Biological Oxygen Demand) of 25 mg O2/l
• COD (Chemical Oxygen Demand) 125 mg O2/l

However, the results of treatment plant were disappointing and re-construction of the wastewater treatment plant is necessary.
