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 where 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.
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 even in large WWTPs (> 150.000 population equivalent) proved the beneficial impact of bioaugmentation on the plant operational status, resulting in:
The sewer network cannot be regarded as only a hydraulic collection and transport system but also a system where some major chemical and biological transformations take place. A characteristic example of the effect of biological conversions in networks is hydrogen sulfide (H2S) production. Its production is associated with health risks, corrosion problems of pipe material, operational problems in the WWTP, as well as severe problems with odor emissions.
By controlled dosing of specialized bacteria in sewer pipes, the following direct results are achieved:
