Bioremediation of Grounds Contaminated With Petroleum Products by HEAP Method
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 10
Abstract
Effective and sustainable reclamation of degraded postindustrial and military areas still requires improvements in methods and approaches. It applies especially for physical, chemical as well as biological remediation methods. In case of the latter method activity of microorganisms is influenced by the environmental conditions which can be controlled by providing the contaminated grounds and the ground waters with biogenic substances. Of no less importance, however, is aeration as well as inoculation the ground using high productive microorganisms in relation to petroleum products degradability. The paper presents a new approach to the bioremediation of areas polluted with hydrocarbons involving implementation of unique closed system of effluents circulation in ex-situ process, use of the selected, dedicated autochthonous microflora capable of hydrocarbons degrading and oxygen degradation conditions. Effectiveness of the implemented remediation method was verified in real environment on the area polluted with hydrocarbons at a former railroad transshipment station. The developed preparations and technology enabled to achieve the contaminants level compliant with the legal purity standards and safe for the environment.
