The Orhei CWTP consists of usual pre-treatment and an equalization with pre-aeration; the primary sedimentation phase has been skipped, because it's carried out directly at the secondary treatment stage by the so-called French system. The system consists of 4 lines operating in parallel independently, each composed of two VF stages in series. Total gross area is about 5 ha. Surely one the largest Constructed Wetlands for secondary treatment of municipal wastewater present worldwide!
