As to the In-Situ-Treatment we cooperate with a dutch company which is specialized in the complete purification of contaminated soils. We offer exploration, consulting services and rehabilitation. The foundation to this work is a special treatment of cleaning soils, which has been developed by an internationally operating chemical company and turned out very reliable in practical experience.
The treatment is designed in a way that it does not cause any considerable disturbance of its environment during the process of cleaning. In the meantime, the biotope is reconstructed in a natural and espacially efficient way.
Our partner is in charge of a primely equipped laboratory for the exploration of the biological activities and opportunities of purification.
The initial point of a rehabilitation is reaching a maximum, sustainable result in consideration of the ecological implications of the rehabilitation during its accomplishment. Additional ecologial damages are avoided, while the rehabilitation is carried out quickly and in a most natural way. It became evident that this methods offer solutions for numerous soil problems, which seemed insolvable quite recently. An economic advantage is provided by the considerably lower cost compared to other treatments of rehabilitation.
The principle of our treatment is based on a nonpolluting approach. On the area that is to be rehabilitated, tubes are sunk into the ground until under the contaminated layer. Through this tubes, air is injected into the soil. In the upmost soil layer, a special bioactive layer is installed, which is produced with the help of so called “starters”. The air streams through the soil and absorbs the contaminants into this layer, where they are quickly and entirely decomposed into CO² and water.
The treatment can be carried out at any location, for example at contaminated industrial locations or in housing areas built on past pollutions. Thereby, the demolition of buildings is not necessary so that the normal employment is not restricted. The treatment is employed in saturated and unsaturated soil layers. It could be proved that this technique of rehabilitation indeed decomposes all organically aerobic and biodegradable materials, including many chemicals employed in industries such as BTEX, hexane, styrol and acrylonitrile. For gasoline stations and the petrochemical industry, where above all petrol and diesel fuels can contaminate the ground, the treatment is a very efficient and economic alternative, too. Costly earthworks and complicated cleaning devices, which consume a lot of space aboveground, are not necessary with this technique. Practical experience has shown that the rehabilitation can be accomplished as deep as 20 metres without problems. During this process no groundwater is extracted, which is why there is no need to fear subsidences. The treatment is especially suitable as far as complex contarminations with an environment that cannot be charged are concerned.
