Bio-Remediation

 

The microbial processes responsible for the biodegradation of organic pollutants in the environment are often very slow. Bioremediation, which is defined as the enhancement of these processes is based on an extensive knowledge of the interaction between the microorganisms and the environment. To establish efficient bioremediation schemes on understanding of the growth, survival and behavior of the specific degrading populations, as well as the environmental facts governing the biodegradation process, is required.

 

In each case bioremediation should be balanced against the potential impact of the contaminants, which means that an environmental impact and risk assessment, together with a decision on soil and groundwater quality standards to be met, should be precede the choice of bioremediation.

 

LGIL has in-house experience in laboratory tests, pilot-scale and fall-scale use of different bioremediation techniques such as nutrient enhanced bioremediation is soil and groundwater, redox potential manipulation, bio-venting, enhancement of bio-availability by detergent additions and inoculations.

 

The MB division conducts microbiological and biochemical tests to separate the microorganism of interest. It also has sufficient facilities to store the organism. An added advantage is that these organisms even work at extreme conditions.

 

As research contractors, LGIL also works to troubleshoot any problem that arises in an industry and designs new Bio-remediation projects solve the same.

 

LGIL’s activities in bio-remediation include:

 

  1. TEnvironmental impact and risk assessment of contaminated soils, sludge and groundwater.
  2. Laboratory tests for the potential effect of bioremediations at a specific site.
  3. Test of aerobic and anaerobic biodegradations potentials of organic chemicals in soil and groundwater, including processes and kinetics, substrate and population dynamics, and microbial toxicity.
  4. Detection, quantifications, and identifications of specific degrade by taxonomic, biochemical and genetic techniques.
  5. Modelling and predictions of contaminant attenuations, biodegradations, and transport in unsaturated soil and aquifers.
  6. Evaluations of bioremediations efficiency based on chemical and ecotoxicological parameters.
  7. Preparations of quality standards for soil and groundwater.
