Project: Wastewater Treatment Plant

Yeganeh Khazar Oil extraction factory, extracts soya oil from soya bean. The resulting wastewater containing vegetable oil & organic compounds which produce following wastewater with chemical & biological characteristics:
1-    COD: 3500 mg/Lit
2-    BOD: 1750 mg/Lit
3-    TSS: 1100 mg/Lit

Since, client intend to recycle completely treated wastewater for existing cooling tower & boiler feed water the existing selected process which could meet above environmental requirement, consisting screening system, oil removal system, MBR system. The selected MBR consist of biological Aeration unit combined with hollow fiber tubular bundles which could sustain suspended solids inside aeration tank and clear water recycled back to the system the result of few years operation revealed that up to 98% of COD  could be removed and turbidity of treated water could reach to less than 0.1 micron.
