Oil decontamination

Scientists of JSC “Biocentras” have developed several technologies of decontamination oil polluted soil and water:

  • decontamination of oil polluted soil and water in situ;
  • decontamination of oil polluted soil and water ex situ;
  • purification of industrial and municipal waste water from oil pollution.

Oil decontamination ex situ

For soil and water polluted as results of technological processing decontamination technology at the cleaning sites and shops was developed. Polluted soil is delivered from contamination place to sites for storage, treatment and recovery.
The biological treatment technology based on biological preparations “Degradoilas” and “Emulvinas” is applied for clearing of soil polluted by oil contaminants at the cleaning sites. The scientists of the company have developed the biological preparations “Degradoilas” and “Emulvinas”. This technology allows avoiding secondary pollution of the nature. Hydrocarbons of oil and oil products degrade to ecologically neutral and environmentally friendly compounds. The cleaned soil reaches the permitted level of pollutions.

The efficiency and operating speed depends on various factors:

  • Structure of oil hydrocarbons;
  • Meteorological conditions;
  • Hoeing technology;
  • Compatibility of actions with the client.

While cleaning contaminated soil in biological technique (using bacterial preparations) in the sites with concrete floor, the soil is transfered to soil fields as the residual amount of heavy hydrocarbons reaches 50 – 100 kg/t (it depends on the initial contamination). It is cleaned according LAND9-2009 requirements.

Oil decontamination from sewage water

JSC “Biocentras” scientists have developed an effective technology for purification of  the sewage water contaminated by oil products. Its’ efficiency allows to clean waste water up to 25 mg/l of suspended matters and up to 1 mg/l of oil products.

Consulting services

The specialists and scientists of JSC “Biocentras” grant professional consultations on environment protection and also prepare the different documentation:

  • Projects for clearing of the environment contaminated by oil;
  • Programs and plans for liquidation of oil overflow emergency;
  • Normative documents and standards of an environment quality.

Design of environmental objects

JSC “Biocentras” designs cleaning sites, shops and washing installations of soil polluted by oil and oil products. The projects are adapted to a particular case, based on the scientific research and modern biotechnological treatment technology, environmentally friendly and allow avoiding secondary pollution of nature.
The specialists of “Biocentras” estimate the influence of the object to the environment, prepare technical and work projects, carry out author’s supervision of constructed objects and also provide engineering consultations.

Cleaning sites for soil polluted by oil

The specialists of JSC “Biocentras” have developed several large projects of environmental protection and the objects were constructed based on these projects:

  • 1992-1995 The utilization shop of non-regenerated oil products has been constructed in Kiškėnai village of Klaipėda region. The projected capacity of the shop is up to 500 t of soil contaminated by oil per year.
  •  1999-2000 The cleaning site of soil polluted by oil and oil products in the territory of Mažeikiai Oil Refinery. The projected capacity of the site is 2000 t of soil contaminated by oil annually. The total area of the cleaning site is 9600 m2.
  • 2005-2006 The expansion of the cleaning site of soil in the territory of Mažeikiai Oil Refinery. The capacity of the site increased to 12 000 t of oil contaminated soil per year.

The main design requirements:

  • To bound the teritory with banks recording to the provided cleaning capability;
  • To set up all required infrastructure – Įrengti reikalingą infrastruktūrą – access roads, driving roads, engineering communications;
  • To set up durable site bottom, suitable for heavy transport to drive but also to transmit water;
  • To plan drain of oiled (fall) water to the cleaning stations with the possibility to reuse it.
  • To plan the possibility to gather soil contaminated with oil during the winter.

According to the cleaning schema, in the teritory of the object soil fields are separated for the nonmigrating heavy oil hydrocarbons final degradation until the allowable standarts using plants.
