Municipal Waste Water

Municipal wastewater treatment stands in the core of our activities. By applying the bioaugmentation technology, the efficiency of a given wastewater treatment plant can be significantly improved both in terms of effluent quality, sludge characteristics and excess sludge production.


Bioaugmentation is a process in which selected, standardized bacteria (microbes) are added to an existing microbial culture (i.e. activated sludge system) resulting in enhancing the ability of the microbial community to respond to process fluctuations, overcome overloading shocks or to degrade certain compounds, resulting in improved overall treatment. The bioaugmentation method developed by Alphabio is based on process optimization with simultaneous dosing of bioaugmentation products.

Implementation in wastewater treatment plants

The application of the bioaugmentation technology is based on the continuous addition of the bacteria in a particular wastewater treatment plant (WWTP) with simultaneous modification of basic plant operational parameters, in order to form the appropriate conditions for their growth. Several applications including large WWTPs (> 150.000 population equivalent) proved the beneficial impact of bioaugmentation on the plant operational status, resulting in:

significant reduction of excess sludge production

improvement of basic effluent quality parameters

reduction of overall energy consumption

reduction of odorous emissions in the plant surroundings

improvement of sludge settling characteristics
