Decontamination of ground water and water surface

The oil pollution of water has great diffusion velocity that causes practically immediate disastrous consequences for the environment. Thereby the liquidation of such contamination is to be carried out very actively by means of environment friendly technologies.

POLYINFORM implements the full complex of works on decontamination of water objects:

  • Decontamination of water surface and costal area from oil pollution
  • Cleaning the water body bottom from various sediments
  • Ground water decontamination

Decontamination of water surface and costal area includes:

  • Localization of the oil spill by bordering with booms, applying sorbents etc
  • collection of oil with special equipment — skimmers
  • Removal of residual oil layer by applying biological product Soilex®
  • Costal area decontamination by applying biological product Soilex®

ADVANTAGES of the technology are following: high decontamination degree, short terms of decontamination, applying of floating bio-sorbents, no impact on the near bottom and bottom layers, cost effectiveness.

Cleaning the water body bottom from various sediments is carried out by means of special equipment including floating excavators, pumps etc.

The applied technology provides working from the water surface. The technology allows successfully cleaning the water bodies from the oil-polluted mud, construction and industrial debris, bank stabilization and deepening works. The removed industrial waste and contaminated mud are utilized at the special yards.

Ground water decontamination is carried out according to special technology.

The contamination of underground water is characterized by large areal of distribution and complexity of the study needed. Therefore hydrogeological investigations are carried out initially, at the basis of which the computer hydrodynamic model of the object is designed, the mapping of areas of the pollution in the gravity-mobile form and in dissolved state filtration and migration parameters of aquifers and the aeration zones are determined and the forecast of contamination migration in aquifers are made.

Depending on the results of hydro-geological study and the degree of the pollution the method of ground water decontamination is chosen.

In case of high contamination, when the lens of oil presence at the underground water surface the pumping out is executed by means of special membranes with the further separation and utilization.

After removing the free oil lens the emulsified oil products stay in the water-bearing rocks and rocks of the aeration zones.

The emulsified or dissolved oil products are eliminated by pumping in the liquid form of biopreparations through the operating wells with the simultaneous aeration of the ground water. The technology also includes washing of the contaminated aquifer.

While the treatment the constant chemical and microbiological control are hold on to adjust the content of microorganisms and essential nutrients in the treated rocks.

Works with use of this technique were performed on dozens of sites in different regions with different climatic conditions.
