5 Working in close cooperation with the petrochemical plant, as well as Czech partners, comprehensive works on subsurface characterization and pilot tests were performed in order to select the best-available technology for soil and groundwater remediation at the vinyl chloride monomer (VCM) plant. With the contamination plume in the upper aquifer delineated and the pump-and-treat technology selected and specified, the actual remediation system was established. With a view to ensuring sustainability of operations, UNEP funded the upgrade and optimization of existing treatment facilities at the VCM plant. Groundwater ater remediation, pilot testing Groundwater remediation, discharge of treated water By January 2004, the system had recovered and treated over 400 tonnes of EDC. Following the training of local partners and the development of clear recommendations for required follow-up measures, the UNEP Clean-up Programme handed over the fullscale remediation system to the site owner in April 2004. The petrochemical plant – HIP PetroHemija – has taken over responsibility for operating and further optimizing the system until clean-up targets, to be regularly reviewed with the national environmental authorities, have been met. Rehabilitation of the wastewater treatment plant The wastewater treatment plant (WWTP) at Pancevo petrochemical plant was not directly targeted during the 1999 bombing. However, damage to the VCM and chloro-alkali plants, and to the oil refinery resulted in the discharge of approximately 170,000 m 3 of raw materials, products and fire-fighting water. This flow overloaded the WWTP’s capacity, damaged process equipment, clogged the units with contaminated sludge, and cracked or otherwise damaged concrete retaining structures. Tric ickling filter reconstruction 34 From Conflict to Sustainable Development
Refurbished tric ickling filter in operation In order to protect the Danube River system and downstream water supplies, the project involved replacing mechanical and instrumental equipment, repairing of the trickling filter and pH regulation facilities, and rehabilitation of the activated sludge unit. This allowed the WWTP to resume treatment of wastewater from the petrochemical plant and Pancevo oil refinery. Consequently, the WWTP’s hydraulic and treatment capacity has been restored, and, following the scheduled completion of further work in June 2004, significantly improved when Repaired activated ated sludge basin interior ior compared with pre-conflict levels. The loading of pollutants entering the Danube River and the associated risks to downstream water supplies and ecology have been significantly reduced. Rehabilitation of wastewater pre-treatment facilities For ormer mer activated ated sludge plant During the 1999 conflict, large quantities of oil, debris and other materials clogged and partly damaged the sewer pipes, oil separators and discharge pipelines at Pancevo oil refinery. Since then, all of the refinery’s wastewater has been discharged directly into the canal and the Danube River without final treatment of oily wastewater at the petrochemical plant’s integrated WWTP.
