Digestate treated using bio-augmentation in Pamukova, Turkey

Digestate treatment
  • 5x capacity increased
  • 75% COD & 85% TKN removal


In the challenging case of Biosun in Pamukova, Turkey, a wastewater treatment plant which is treating digastate from an anaerobic plant for biogas production asked for the implementation of bio-augmentation in order to comply with municipal sewer network quality standards. The plant has now an influent flowrate of 100-120 m3/d with an average COD and TSS of 30,000 and 25,000 mg/L respectively. The plant has achieved to increase the quantity of treated waste by five times, also to improve the reduction of COD, TSS, NH4 and TP, while the severe clogging phenomena that the membrane bioreactor was facing have been effectively mitigated.
