The WWTP of Dedmold with a wastewater flowrate of 20,000 – 25,000 m3/d came in touch with Alpha-Bioenergy aiming to reduce the excess sludge that was produced in the plant. After the implementation of bio-augmentation in the plant, a 25% reduction in the excess sludge was observed.
In December 2015, Alpha-Bioenergy started a pilot bio-augmentation application in the municipal wastewater treatment facilities of Corfu, which is still in act, because the municipality was searching for a way to minimize the sludge produced in the facilities due to high cost of disposal.
In January 2014, Alpha-Bioenergy and the municipal wastewater treatment facilities of Patras started cooperating for the reduction of the produced sludge. The municipality was searching for a way to minimize the sludge produced in the facilities due to high cost of disposal.
In October 2014, the municipality of Kastoria and Alpha-Bioenergy agreed in the pilot application of bio-augmentation in the wastewater treatment facilities of the town. The application is continuing until today. The plant has an average flowrate of 8000 m3/d which is fluctuating due to heavy seasonal rains (12000-15000 m3/d).
The implementation of the bioaugmentation process in the Heraklion city WWTP commenced in August of 2015 and is still running. Heraklion WWTP, receives wastewater from the Municipality of Heraklion, the fourth most populated city of Greece and biggest city of the island of Crete.
