Stormwater treatment plant with oil separator greenfort series os in power plant

Industry	Power engineering Industry
Type	Stormwater treatment
Task	To obtain treated water that complies with the requirements for discharging it into surface water bodies
Water source	Stormwater

About the project

The equipment is designed and manufactured for industrial rainwater treatment facilities. It was the first project where the oil separator GreenFort series OS was installed. Oil separator GreenFort series OS is designed by our engineers and manufactured in our facilities.

Summarise

Treated water from the stormwater treatment is discharged to the surface waterbodies, so it is important to reduce the oil products. The oil separator GreenFort series OS was designed for the treatment of backwash water of mechanical and active carbon filters with oil/petroleum products contamination by the thin-layered sedimentation tank.
