The waters protection against pollution with hazardous and harmful substances is an important segment of the environmental protection strategy in HIP-Pertohemija a.d. Pančevo.
HIP-Petrohemija a.d. Pančevo within its complex, at the locations of Pančevo and Elemir, has a modern system installation for waste waters collection and treatment.
The waste waters from the process, as well as sanitary, atmospheric and surface water from the closed sewage system, after the pre-treatment, are sent for treatment to either the central Waste Water Treatment Plant in Pančevo, or to the Waste Water Treatment Unit in Elemir respectively.
The Waste Water Treatment Plant in Pančevo includes primary treatment (equalization, neutralization, flocculation and flotation) and secondary treatment (two-stage biological treatment through bio-filter and active sludge) of waste waters, as well as dehydration and stabilization of the extracted sludge.
The Waste Water Treatment Unit in Elemir includes the external sewage pumping station, waste water purification system for separation of lighter and heavier water components and biological decomposition of organic matters.
Waste waters monitoring includes the following:
• monitoring of waste waters at the place where they are produced (internal flows);
• monitoring of waste waters at the place of release into recipient (the Danube, the Tisa);
• monitoring of waste water impact on the recipient quality (upstream, at the spot of confluent, and downstream).
