The Waste Water Treatment Plant represents one of the most important links in the environment protection chain within HIP-Petrohemija. It was designed to accept and process waste waters not only from all of the HIP-Petrohemija's production plants, but also from the neighboring NIS Oil Refinery Pančevo. The plant was put in operation in 1980, and the waste-waters-extracted sludge processing line was commissioned in 1991.

A modern method for treatment of waste waters consists of an entire petrochemical complex closed sewage system, of a pre-treatment in the production plants, of a special treatment of caustic water flow from the Ethylene plant and of a central waste waters treatment plant.

Physical and chemical treatment including equalization, neutralization, flocculation and flotation and two-stage biological treatment of the waste waters (through a bio-filter and active charcoal), as well as dehydratation and stabilization of the extracted sludge are all performed in the Waste Water Treatment Plant.

The plant's processing capacity is 750 m³ per hour. The key parameters through which one can verify the efficiency of a waste water treatment plant's operation – are the reduction levels of the oil content, of the phenol content and of the chemical and biological oxygen consumption. The water treatment in our plant achieves reduction levels superior to 90%, which tell us of the high purification levels, as well as of efficiency and comparative advantages of the aerobic biological treatment used within the secondary water treatment.
