REMARKS

  • The wastewater parameters entering the WWTP were significantly reduced resulting in the overall reduction of incoming loading.
  • Odors, fats, oils and grease in the sewer grid, manholes and pumping stations were eliminated.
  • Sewer pipelines and pumping stations were cleaned and therefore the standard cleaning maintenance was not required

Case StudyLAKE REHABILITATION
LocationNorthern Greece
TargetWater Quality Improvement & Odour Control
Populations Equivalent280 000 m3
Flowrate< 30 m3 /hr
Treated wastewaterSurface &Treated sewage water

REMARKS

  • Two lakes were treated
  • Lake No1 approximate volume 30 000 m3 and Lake No2 of 250 000 m3
  • The inflow id surface water and effluent from a wastewater treatment plant
  • The implementation target is rehabilitation of the two lakes
  • Combination of Facultative Microorganisms were used over three months
  • An increased dosage was used during the cultivation period (first month of application)
  • Total microbial product quantity used was approximately 110 kg
  • All monitored parameters (Turbidity, TN, TP etc.) were improved and the rehabilitation was achieved
