Pollution causes
The environmental pollution, which is the subject of this project, can be mainly linked to the already liquidated, state-owned Peremarton Chemical Enterprise. The enterprise carried out various chemical industry-related activities — e.g. production of fertilizers, plant protective products and inorganic primary materials — in its many plants located there. Because of its operation and inappropriate waste management, polluting agents escaped into the environment in diversified surface and quality distribution patterns. Typical soil polluting agents are arsenic, nickel and lead, while the ground water was mainly polluted with sulphates, nitrates, ammonium and chlorobenzene.
The remediation project
The project goal was the removal of improperly stored waste and polluted geological layers, which act as polluting sources of the area, purification of the polluted ground water and liquidation of any associated environmental and human health risks.
Special project features
The remediation is done in an industrial park that is under continuous operation, and requires special cooperation between the contractor and companies working there.
We had to build two parallel water treatment systems in the industrial park, one of them dedicated exclusively to the removal of the chlorobenzene contamination.
Main project data
Excavation and removal of soil contaminated with toxic metals: 36,700 tons.
Dumping-ground formed on the site, with a storage capacity of 36,138 tons.
Implementation of a drain system on area with public utilities:
- 4,065 linear metre drain ditch at 4 to 8 metres depth, and 800 m 3 drain bed;
- collecting shafts with mechanical components.
Water purification system:
- separate chlorobenzene removal (with 1 m3/d capacity) at the synthesis plant;
- calciferous aluminium-sulphate precipitation; biological wastewater purification using activated sludge. Post-treatment: ionic replacement, RO.
Drainage system for full soil flush-out: gravel adsorption bed with back-feed drain pipes: 2,685 linear metres; gravel adsorption bed: 4,500 m3.
Time period: from 2013 to 2015 (expected end of water purification: 2020)
Financing: EU and Hungarian State: 100%
Project codename: KEOP-2.4.0./2F/09-11-2012-0003
Client: Hungarian National Asset Management
Total project value: approx. €15.5 million
