This presentation is about bioremediation, which means the recovering.

1. BIOREMEDIATION
-NAV NANDH TEJ

2.  BIO- LIFE
 REMEDIATE- To restore something that is wrong
(or) damaged (or) to improve a bad situation.

3. Bio-remediation is a process
used to treat contaminated media, including water,
soil by using micro-organisms, plant enzymes etc.
BIO-REMEDIATION

4. BIOREMEDIATION CYCLE

5. BIO-REMEDIATION
IN-SITU EX-SITU
 Selection of technology is based on several fields:-
1. Types of micro-organisms 2. Pollutant concentration
3. Environment 4. Nutrient availibility
BIO-REMEDIATION TECHNOLOGIES

6. The process of remediating
contaminated soil (or) contaminated water at site of
contamination.
IN-SITU TECHNOLOGY

7.  The process of remediating
contaminated soil (or) ground water by extracting out from
site of contamination.
EX-SITU TECHNOLOGY

8. INTRENSIC BIOREMEDIATION ENGENEERED IN-SITU
BIOREMEDIATION
BIO-STIMULATION BIO-AUGMENTATION
BIO-VENTING
BIO-PARGING
IN-SITU TECHNOLOGY TYPES

9.  The simulation of native microbial
population in soil (or) ground water by providing necessary
nutrients.
BIO-STIMULATION

10.  The addition of exogenous bacterial
cultures ,which increases capability of degrading
contamination to contaminant site.
 EXAMPLE:- Cleaning of soil contaminant with aromatic
compounds.
BIO-AUGUMENTATION

11.  The process of treating
contaminated soils by drawing oxygen through the vadose
region [ unsaturated soil above ground water] of soil to
stimulate microbial activity.
BIO-VENTING

12.  The process of treating
contaminated water by injecting air below the water and
able to stimulate microbial activity.
BIO-SPARGING

13.  Can treat larger volume of soil at once
 Create less dust
 Need of less labor and equipment's
 Nature based process
ADVANTAGES

14.  Slower remediation rate than ex-situ
 Limited by depth of soil
 Time taking [months-years]
 Less predictable.
DIS-ADVANTAGES

15.  Environmentally friendly
 Bioremediation allows microbes as natural organisms to
degrade toxic compounds
 Bioremediation is one of the most developing methods to
restore environment.
CONCLUSION
