    Until the mid 1950’s there was a functioning gravel mine in a part of the 18th district of Budapest (Pestlőrinc). During the mining operations several foundation pits were formed, and some of them was used as a temporary crude-oil storage, which lead to the formation of the so-called „crude-oil lakes”. In 1997 the local government invited entries for a competition for damage control and remediation, which was won by our company.
    Additionally the local government also applied for a subsidy, which could have been used for the experimental application of new technologies, which were already known from foreign technical literature, but were previously never used in the Hungarian practice. This subsidy was won by two other companies.
    The aim of CEVA Magyarország Ltd. was utilization of a thermal desorption method for soil cleaning, but the settings of the equipment from the USA was unsuitable to use in Hungarian electrical network. During their work several modifications were needed, and considering the available financial resources, the method proved to be extremely expensive.
    The GENDER Budapest Ltd. wanted to use HARDOIL technology to skim the residual thin crude-oil layer on the surface of the lakes. Additionally the company planned the biological treatment of the soils as well. In the end their methods and works did not prove to be effective enough so the task of crude-oil skimming and biological soil cleaning was taken over by our company.
    During our operations 26 000 tons of crude-oil was skimmed from the surface of
    the lakes and 490 m3 from the surface of the groundwater, and 35 490 m3 lake water and 250 000 m3 groundwater was pumped and treated with air-stripper towers. As a result the floating crude-oil layer and the contamination of the lakes was completely eliminated.
    In case of soil treatment, only the activity of our company proved to be effective and cost-efficient enough. We used ex situ enzymatic biological technology to treat nearly 120 000 m3 soil from an area of 74 000 m2, and decreased the concentration of the soil contamination from the initial
    50 000 mg/kg to 2000 mg/kg.
