November 2019 - March 2020

Sewerage grid system

Our company undertook to implement the bioaugmentation method at the City of Virovitica with a four month contract. The perfect communication of both sides led to a efficient cooperation with multiple positive results for the sewerage system grid of the city.

The daily injection of microorganisms in strategic location at the sewerage system grid helped to achieve the results of our method.

At this little time of our contract our method achieved:

 

1) Fats, oils and grease (FOG) at 50% 

2) Chemical oxygen demand (COD) at 66%

3) Suspended solids (SS) at 60%.

4) Total Phosphorus (TP) at 65%

5) Total Nitrogen (TN) at 23%

Except for the degradation of the influent parameters our method achieved the following

Elimination of odours

Elimination of odours has been taken place accross the whole sewerage system grid  of the city of Virovitica. Pumping stations and pipelines do not produce any "bad" smells anymore.
