Ganir is an Israel-based fruit juice production plant. 1000-1500 m³/day fruit juice wastewater originates from peel processing and juice production.

The peel press liquor contains etheric oil which is toxic to biological biomass. The wastewater is discharged to the local municipal WWTP, and complies with the local discharge limits.

The WWTP is based on a 2,000 m³ high rate anaerobic UASB (Up-flow Anaerobic Sludge Blanket) reactor. The pretreatment of the peel press liquor is based on a DAF unit, which recovers the etheric oil prior its entrance to the biological treatment.

The biogas, which is produced during the anaerobic fermentation, is used for steam production in a 2 ton/hour dedicated steam boiler.
