EXPRESSION OF INTEREST

Defence Research & Development Establishment, (DRDE),

Defence Research & Development Organization (DRDO)

Govt. of India, Minist ry of Defence, Jhansi Road, Gwalior-474002

Invitation of expression of interest (EOI) for QA/QC service of Anaerobic Microbial

Inoculum (AMI) and i ts generation facili ty.

DRDE, Gwalior is engaged in developing biodigester based eco-friendly technologies

for disposal of organic wastes for all weather and climatic conditions for the last three

decades. DRDE has developed an innovative technology for disposal of human waste

in eco-friendly manner at locations where temperature drops to -40°C or lower. It is not

only useful for glacier and other snow bound areas but can also be used effectively in

any other geo-climatic conditions prevailing in different parts of the world. The process

culminates in the treated effluent which is safe and is also environmentally acceptable.

During waste treatment colourless, inflammable biogas (methane) is generated as a

byproduct. The technology has two major components:

1. Low temperature active bacterial inoculum

2. Biodigester.

A consortium of anaerobic bacteria has been formulated and adapted to work at

temperature as low as 5°C. This is the component which acts as inoculum (seed

material) for the biodigester and converts the organic waste into methane and carbondioxide. The anaerobic process inactivates the pathogens responsible for water borne

diseases. Biodigester serves as reaction vessel for biomethanation as well as provides

the anaerobic conditions and required temperature for the bacterial growth. The

optimum temperature for biodegradation is maintained by microbial heat, insulation of

the reactor and/ or solar heating.

1. Suitable for sub zero temperature of Himalayan region as well as tropical and dry

climates.

Salient features:

2. No dependence on the limited and costly conventional energy sources.3. Easy to transport and install in hilly terrains.

4. Elimination of pathogens.

5. Generation of odourless and inflammable biogas.

6. Extremely low maintenance requirement.

7. Economically viable

The technology of Biodigester is expanding its wings in different regions of the country

like Lakshadweep and Indian Railways. And the key component of the technology is

Anaerobic Microbial Inoculum (AMI). It’s appropriate quality is of utmost importance for

the success of the biodigester technology. To cater to such a huge requirement of AMI,

several industries have taken the technology for biodigester as well as AMI production.

Industry is producing the AMI and supplying to users for which QA/QC of AMI and its

production facility is essential. QA/ QC of the AMI and the production facility will be

carried out by the interested vendors. QA/QC of anaerobic microbial inoculum has to be

monitored during mother culture stage at production site before seeding at user end.

Quality of inoculum is refers to the number of viable hydrolytic and methanogenic

bacteria per milliliter of inoculum. Other parameters to be analyzed for QA/QC of

anaerobic microbial inoculum include pH, biogas production and methane content of

biogas. QA/QC of production facility should be monitored half yearly (observation to be

made according to check list attached). Vendor will generate data as per QA/QC

document provided by DRDE Gwalior and submit its recommendations for issuing

QA/QC certificate to both the Production facility as well as individual batches ofinoculum.

Target values for anaerobic microbial inoculum are follows.

S No. Parameters Target value

1 pH 6.5 – 7.5

2 Biogas inflammability Inflammable

3 Methane content of biogas 40 – 70 %

4 Total solid content 3 – 4 %

5 Hydrolytic bacteria count (CFU/ml) > 105

6 Methanogens count (CFU/ml) > 103

Production facility should be monitored for the following parameters

1. Engineering drawing of the AMI (Anaerobic Microbial Inoculum) production facility.

2. pH meter, Temperature sensor and biogas flow meter connected with data logger

for round the clock monitoring.

3. Installation of chiller unit and inoculum mixing arrangement.

4. Maintenance of records for pH, Temperature, Gas flow and cattle dung feed etc.

5. Hermetical sealing of the plant and testing the inflammability of biogas on the spot.

Interested vendors/parties may send the offer for expression of interest (EOI) along with

the following documents within 30 days from date of publication. The response shall

contain;


3/3

1. Company profile

2. Details of QA/QC services offered earlier.

3. Any other document which can establish the experience and the expertise of the

interested vendor.

On the top of the envelop, it should be marked as Expression of interest for QA/QC of AMI. For inquiries regarding this EOI, please contact the Director, DRDE, Gwalior-

474002, Phone No. 0751-2233490/2341550, Fax No. 0751-2341148.
